-# Contributor Covenant Code of Conduct
-
-## Our Pledge
-
-We as members, contributors, and leaders pledge to make participation in our
-community a harassment-free experience for everyone, regardless of age, body
-size, visible or invisible disability, ethnicity, sex characteristics, gender
-identity and expression, level of experience, education, socio-economic status,
-nationality, personal appearance, race, religion, or sexual identity
-and orientation.
-
-We pledge to act and interact in ways that contribute to an open, welcoming,
-diverse, inclusive, and healthy community.
-
-## Our Standards
-
-Examples of behavior that contributes to a positive environment for our
-community include:
-
-* Demonstrating empathy and kindness toward other people
-* Being respectful of differing opinions, viewpoints, and experiences
-* Giving and gracefully accepting constructive feedback
-* Accepting responsibility and apologizing to those affected by our mistakes,
-  and learning from the experience
-* Focusing on what is best not just for us as individuals, but for the
-  overall community
-
-Examples of unacceptable behavior include:
-
-* The use of sexualized language or imagery, and sexual attention or
-  advances of any kind
-* Trolling, insulting or derogatory comments, and personal or political attacks
-* Public or private harassment
-* Publishing others' private information, such as a physical or email
-  address, without their explicit permission
-* Other conduct which could reasonably be considered inappropriate in a
-  professional setting
-
-## Enforcement Responsibilities
-
-Community leaders are responsible for clarifying and enforcing our standards of
-acceptable behavior and will take appropriate and fair corrective action in
-response to any behavior that they deem inappropriate, threatening, offensive,
-or harmful.
-
-Community leaders have the right and responsibility to remove, edit, or reject
-comments, commits, code, wiki edits, issues, and other contributions that are
-not aligned to this Code of Conduct, and will communicate reasons for moderation
-decisions when appropriate.
-
-## Scope
-
-This Code of Conduct applies within all community spaces, and also applies when
-an individual is officially representing the community in public spaces.
-Examples of representing our community include using an official e-mail address,
-posting via an official social media account, or acting as an appointed
-representative at an online or offline event.
-
-## Enforcement
-
-Instances of abusive, harassing, or otherwise unacceptable behavior may be
-reported to the community leaders responsible for enforcement at
-support@sftpgo.com.
-All complaints will be reviewed and investigated promptly and fairly.
-
-All community leaders are obligated to respect the privacy and security of the
-reporter of any incident.
-
-## Enforcement Guidelines
-
-Community leaders will follow these Community Impact Guidelines in determining
-the consequences for any action they deem in violation of this Code of Conduct:
-
-### 1. Correction
-
-**Community Impact**: Use of inappropriate language or other behavior deemed
-unprofessional or unwelcome in the community.
-
-**Consequence**: A private, written warning from community leaders, providing
-clarity around the nature of the violation and an explanation of why the
-behavior was inappropriate. A public apology may be requested.
-
-### 2. Warning
-
-**Community Impact**: A violation through a single incident or series
-of actions.
-
-**Consequence**: A warning with consequences for continued behavior. No
-interaction with the people involved, including unsolicited interaction with
-those enforcing the Code of Conduct, for a specified period of time. This
-includes avoiding interactions in community spaces as well as external channels
-like social media. Violating these terms may lead to a temporary or
-permanent ban.
-
-### 3. Temporary Ban
-
-**Community Impact**: A serious violation of community standards, including
-sustained inappropriate behavior.
-
-**Consequence**: A temporary ban from any sort of interaction or public
-communication with the community for a specified period of time. No public or
-private interaction with the people involved, including unsolicited interaction
-with those enforcing the Code of Conduct, is allowed during this period.
-Violating these terms may lead to a permanent ban.
-
-### 4. Permanent Ban
-
-**Community Impact**: Demonstrating a pattern of violation of community
-standards, including sustained inappropriate behavior,  harassment of an
-individual, or aggression toward or disparagement of classes of individuals.
-
-**Consequence**: A permanent ban from any sort of public interaction within
-the community.

-  The GNU Affero General Public License is a free, copyleft license for
-software and other kinds of works, specifically designed to ensure
-cooperation with the community in the case of network server software.
+  The GNU General Public License is a free, copyleft license for

+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
 
   When we speak of free software, we are referring to freedom, not
 price.  Our General Public Licenses are designed to make sure that you

 want it, that you can change the software or use pieces of it in new
 free programs, and that you know you can do these things.
 
-  Developers that use our General Public Licenses protect your rights
-with two steps: (1) assert copyright on the software, and (2) offer
-you this License which gives you legal permission to copy, distribute
-and/or modify the software.
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
 
-  A secondary benefit of defending all users' freedom is that
-improvements made in alternate versions of the program, if they
-receive widespread use, become available for other developers to
-incorporate.  Many developers of free software are heartened and
-encouraged by the resulting cooperation.  However, in the case of
-software used on network servers, this result may fail to come about.
-The GNU General Public License permits making a modified version and
-letting the public access it on a server without ever releasing its
-source code to the public.
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
 
-  The GNU Affero General Public License is designed specifically to
-ensure that, in such cases, the modified source code becomes available
-to the community.  It requires the operator of a network server to
-provide the source code of the modified version running there to the
-users of that server.  Therefore, public use of a modified version, on
-a publicly accessible server, gives the public access to the source
-code of the modified version.
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
 
-  An older license, called the Affero General Public License and
-published by Affero, was designed to accomplish similar goals.  This is
-a different license, not a version of the Affero GPL, but Affero has
-released a new version of the Affero GPL which permits relicensing under
-this license.
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.

+Full featured and highly configurable SFTP server
 
-Full-featured and highly configurable event-driven file transfer solution. Server protocols: SFTP, HTTP/S, FTP/S, WebDAV. Storage backends: local filesystem, encrypted local filesystem, S3 (compatible) Object Storage, Google Cloud Storage, Azure Blob Storage, other SFTP servers.
+## Features
 
-With SFTPGo you can leverage local and cloud storage backends for exchanging and storing files internally or with business partners using the same tools and processes you are already familiar with.
+- Each account is chrooted to his Home Dir.
+- SFTP accounts are virtual accounts stored in a "data provider".
+- SQLite, MySQL, PostgreSQL, bbolt (key/value store in pure Go) and in memory data providers are supported.
+- Public key and password authentication. Multiple public keys per user are supported.
+- Custom authentication using external programs is supported.
+- Quota support: accounts can have individual quota expressed as max total size and/or max number of files.
+- Bandwidth throttling is supported, with distinct settings for upload and download.
+- Per user maximum concurrent sessions.
+- Per user and per directory permissions: list directories content, upload, overwrite, download, delete, rename, create directories, create symlinks, changing owner/group and mode, changing access and modification times can be enabled or disabled.
+- Per user files/folders ownership: you can map all the users to the system account that runs SFTPGo (all platforms are supported) or you can run SFTPGo as root user and map each user or group of users to a different system account (*NIX only).
+- Per user IP filters are supported: login can be restricted to specific ranges of IP addresses or to a specific IP address.
+- Configurable custom commands and/or HTTP notifications on file upload, download, delete, rename, on SSH commands and on user add, update and delete.
+- Automatically terminating idle connections.
+- Atomic uploads are configurable.
+- Support for Git repositories over SSH.
+- SCP and rsync are supported.
+- Prometheus metrics are exposed.
+- REST API for users management, backup, restore and real time reports of the active connections with possibility of forcibly closing a connection.
+- Web based interface to easily manage users and connections.
+- Easy migration from Linux system user accounts.
+- Portable mode: a convenient way to share a single directory on demand.
+- Configuration is a your choice: JSON, TOML, YAML, HCL, envfile are supported.
+- Log files are accurate and they are saved in the easily parsable JSON format.
 
-## Project Status & Editions
+## Platforms
 
-SFTPGo is an open-source project with a sustainable business model. We offer two editions to suit different requirements, ensuring the project remains healthy and maintained for everyone.
+SFTPGo is developed and tested on Linux. After each commit the code is automatically built and tested on Linux and macOS using Travis CI.
+Regularly the test cases are manually executed and pass on Windows. Other UNIX variants such as *BSD should work too.
 
-### Open Source (Community)
+## Requirements
 
-Free, Copyleft (AGPLv3), Community Supported. The Community edition is a fully functional, production-ready solution widely adopted worldwide. It includes all the core protocols, storage backends, and the WebAdmin/WebClient UIs. It is ideal for:
+- Go 1.13 or higher as build only dependency.
+- A suitable SQL server or key/value store to use as data provider: PostreSQL 9.4+ or MySQL 5.6+ or SQLite 3.x or bbolt 1.3.x
 
-- Standard file transfer needs.
-- Integrating storage backends (S3, GCS, Azure Blob) with legacy protocols.
-- Projects that are comfortable with AGPLv3 licensing.
+## Installation

+- For Arch Linux via AUR:
+  - [sftpgo](https://aur.archlinux.org/packages/sftpgo/). This package follow stable releases. It requires `git`, `gcc` and `go` to build.
+  - [sftpgo-bin](https://aur.archlinux.org/packages/sftpgo-bin/). This package follow stable releases downloading the prebuilt linux binary from GitHub. It does not require `git`, `gcc` and `go` to build.
+  - [sftpgo-git](https://aur.archlinux.org/packages/sftpgo-git/). This package build and install the latest git master. It requires `git`, `gcc` and `go` to build.

-Your sponsorship helps cover maintenance, security updates and ongoing development of the open-source edition.
+Make sure [Git](https://git-scm.com/downloads) is installed on your machine and in your system's `PATH`.
 
-### Thank you to our sponsors
+SFTPGo depends on [go-sqlite3](https://github.com/mattn/go-sqlite3) that is a CGO package and so it requires a `C` compiler at build time.
+On Linux and macOS a compiler is easy to install or already installed, on Windows you need to download [MinGW-w64](https://sourceforge.net/projects/mingw-w64/files/) and build SFTPGo from its command prompt.
 
-#### Platinum sponsors
+The compiler is a build time only dependency, it is not not required at runtime.

-</br></br>
-[<img src="./img/wpengine.png" alt="WP Engine logo" width="331" height="63">](https://wpengine.com/)
+If you don't need SQLite, you can also get/build SFTPGo setting the environment variable `GCO_ENABLED` to 0, this way SQLite support will be disabled but PostgreSQL, MySQL, bbolt and memory data providers will work and you don't need a `C` compiler for building.
 
-#### Silver sponsors
+Version info, such as git commit and build date, can be embedded setting the following string variables at build time:

-- Community Edition: Remains maintained, receiving bug fixes, security updates, and updates to core features.
+- `--config-dir` string. Location of the config dir. This directory should contain the `sftpgo` configuration file and is used as the base for files with a relative path (eg. the private keys for the SFTP server, the SQLite or bblot database if you use SQLite or bbolt as data provider). The default value is "." or the value of `SFTPGO_CONFIG_DIR` environment variable.
+- `--config-file` string. Name of the configuration file. It must be the name of a file stored in config-dir not the absolute path to the configuration file. The specified file name must have no extension we automatically load JSON, YAML, TOML, HCL and Java properties. The default value is "sftpgo" (and therefore `sftpgo.json`, `sftpgo.yaml` and so on are searched) or the value of `SFTPGO_CONFIG_FILE` environment variable.
+- `--log-compress` boolean. Determine if the rotated log files should be compressed using gzip. Default `false` or the value of `SFTPGO_LOG_COMPRESS` environment variable (1 or `true`, 0 or `false`). It is unused if `log-file-path` is empty.
+- `--log-file-path` string. Location for the log file, default "sftpgo.log" or the value of `SFTPGO_LOG_FILE_PATH` environment variable. Leave empty to write logs to the standard error.
+- `--log-max-age` int. Maximum number of days to retain old log files. Default 28 or the value of `SFTPGO_LOG_MAX_AGE` environment variable. It is unused if `log-file-path` is empty.
+- `--log-max-backups` int. Maximum number of old log files to retain. Default 5 or the value of `SFTPGO_LOG_MAX_BACKUPS` environment variable. It is unused if `log-file-path` is empty.
+- `--log-max-size` int. Maximum size in megabytes of the log file before it gets rotated. Default 10 or the value of `SFTPGO_LOG_MAX_SIZE` environment variable. It is unused if `log-file-path` is empty.
+- `--log-verbose` boolean. Enable verbose logs. Default `true` or the value of `SFTPGO_LOG_VERBOSE` environment variable (1 or `true`, 0 or `false`).
+
+If you don't configure any private host keys, the daemon will use `id_rsa` in the configuration directory. If that file doesn't exist, the daemon will attempt to autogenerate it (if the user that executes SFTPGo has write access to the config-dir). The server supports any private key format supported by [`crypto/ssh`](https://github.com/golang/crypto/blob/master/ssh/keys.go#L32).
+
+Before starting `sftpgo` a dataprovider must be configured.
+
+SQL scripts to create the required database structure can be found inside the source tree [sql](./sql "sql") directory. The SQL scripts filename is, by convention, the date as `YYYYMMDD` and the suffix `.sql`. You need to apply all the SQL scripts for your database ordered by name, for example `20190828.sql` must be applied before `20191112.sql` and so on.
+
+The `sftpgo` configuration file contains the following sections:
+
+- **"sftpd"**, the configuration for the SFTP server
+    - `bind_port`, integer. The port used for serving SFTP requests. Default: 2022
+    - `bind_address`, string. Leave blank to listen on all available network interfaces. Default: ""
+    - `idle_timeout`, integer. Time in minutes after which an idle client will be disconnected. 0 menas disabled. Default: 15
+    - `max_auth_tries` integer. Maximum number of authentication attempts permitted per connection. If set to a negative number, the number of attempts are unlimited. If set to zero, the number of attempts are limited to 6.
+    - `umask`, string. Umask for the new files and directories. This setting has no effect on Windows. Default: "0022"
+    - `banner`, string. Identification string used by the server. Leave empty to use the default banner. Default "SFTPGo_version"
+    - `upload_mode` integer. 0 means standard, the files are uploaded directly to the requested path. 1 means atomic: files are uploaded to a temporary path and renamed to the requested path when the client ends the upload. Atomic mode avoids problems such as a web server that serves partial files when the files are being uploaded. In atomic mode if there is an upload error the temporary file is deleted and so the requested upload path will not contain a partial file. 2 means atomic with resume support: as atomic but if there is an upload error the temporary file is renamed to the requested path and not deleted, this way a client can reconnect and resume the upload.
+    - `actions`, struct. It contains the command to execute and/or the HTTP URL to notify and the trigger conditions. See the "Custom Actions" paragraph for more details
+        - `execute_on`, list of strings. Valid values are `download`, `upload`, `delete`, `rename`, `ssh_cmd`. Leave empty to disable actions.
+        - `command`, string. Absolute path to the command to execute. Leave empty to disable.
+        - `http_notification_url`, a valid URL. An HTTP GET request will be executed to this URL. Leave empty to disable.
+    - `keys`, struct array. It contains the daemon's private keys. If empty or missing the daemon will search or try to generate `id_rsa` in the configuration directory.
+        - `private_key`, path to the private key file. It can be a path relative to the config dir or an absolute one.
+    - `enable_scp`, boolean. Default disabled. Set to `true` to enable the experimental SCP support. This setting is deprecated and will be removed in future versions, please add `scp` to the `enabled_ssh_commands` list to enable it
+    - `kex_algorithms`, list of strings. Available KEX (Key Exchange) algorithms in preference order. Leave empty to use default values. The supported values can be found here: [`crypto/ssh`](https://github.com/golang/crypto/blob/master/ssh/common.go#L46 "Supported kex algos")
+    - `ciphers`, list of strings. Allowed ciphers. Leave empty to use default values. The supported values can be found here: [`crypto/ssh`](https://github.com/golang/crypto/blob/master/ssh/common.go#L28 "Supported ciphers")
+    - `macs`, list of strings. available MAC (message authentication code) algorithms in preference order. Leave empty to use default values. The supported values can be found here: [`crypto/ssh`](https://github.com/golang/crypto/blob/master/ssh/common.go#L84 "Supported MACs")
+    - `login_banner_file`, path to the login banner file. The contents of the specified file, if any, are sent to the remote user before authentication is allowed. It can be a path relative to the config dir or an absolute one. Leave empty to send no login banner
+    - `setstat_mode`, integer. 0 means "normal mode": requests for changing permissions, owner/group and access/modification times are executed. 1 means "ignore mode": requests for changing permissions, owner/group and access/modification times are silently ignored.
+    - `enabled_ssh_commands`, list of enabled SSH commands. These SSH commands are enabled by default: `md5sum`, `sha1sum`, `cd`, `pwd`. `*` enables all supported commands. Some commands are implemented directly inside SFTPGo, while for other commands we use system commands that need to be installed and in your system's `PATH`. For system commands we have no direct control on file creation/deletion and so quota check is suboptimal: if quota is enabled, the number of files is checked at the command begin and not while new files are created. The allowed size is calculated as the difference between the max quota and the used one and it is checked against the bytes transferred via SSH. The command is aborted if it uploads more bytes than the remaining allowed size calculated at the command start. Anyway we see the bytes that the remote command send to the local command via SSH, these bytes contain both protocol commands and files and so the size of the files is different from the size trasferred via SSH: for example a command can send compressed files or a protocol command (few bytes) could delete a big file. To mitigate this issue quotas are recalculated at the command end with a full home directory scan, this could be heavy for big directories. If you need system commands and quotas you could consider to disable quota restrictions and periodically update quota usage yourself using the REST API. We support the following SSH commands:
+      - `scp`, SCP is an experimental feature, we have our own SCP implementation since we can't rely on "scp" system command to proper handle quotas and user's home dir restrictions. The SCP protocol is quite simple but there is no official docs about it, so we need more testing and feedbacks before enabling it by default. We may not handle some borderline cases or have sneaky bugs. Please do accurate tests yourself before enabling SCP and let us known if something does not work as expected for your use cases. SCP between two remote hosts is supported using the `-3` scp option.
+      - `md5sum`, `sha1sum`, `sha256sum`, `sha384sum`, `sha512sum`. Useful to check message digests for uploaded files. These commands are implemented inside SFTPGo so they work even if the matching system commands are not available, for example on Windows.
+      - `cd`, `pwd`. Some SFTP clients does not support the SFTP SSH_FXP_REALPATH packet type and so they use `cd` and `pwd` SSH commands to get the initial directory. Currently `cd` do nothing and `pwd` always returns the `/` path.
+      - `git-receive-pack`, `git-upload-pack`, `git-upload-archive`. These commands enable support for Git repositories over SSH, they need to be installed and in your system's `PATH`.
+      - `rsync`. The `rsync` command need to be installed and in your system's `PATH`. We cannot avoid that rsync create symlinks so if the user has the permission to create symlinks we add the option `--safe-links` to the received rsync command if it is not already set. This should prevent to create symlinks that point outside the home dir. If the user cannot create symlinks we add the option `--munge-links`, if it is not already set. This should make symlinks unusable (but manually recoverable)
+- **"data_provider"**, the configuration for the data provider
+    - `driver`, string. Supported drivers are `sqlite`, `mysql`, `postgresql`, `bolt`, `memory`
+    - `name`, string. Database name. For driver `sqlite` this can be the database name relative to the config dir or the absolute path to the SQLite database.
+    - `host`, string. Database host. Leave empty for drivers `sqlite`, `bolt` and `memory`
+    - `port`, integer. Database port. Leave empty for drivers `sqlite`, `bolt` and `memory`
+    - `username`, string. Database user. Leave empty for drivers `sqlite`, `bolt` and `memory`
+    - `password`, string. Database password. Leave empty for drivers `sqlite`, `bolt` and `memory`
+    - `sslmode`, integer. Used for drivers `mysql` and `postgresql`. 0 disable SSL/TLS connections, 1 require ssl, 2 set ssl mode to `verify-ca` for driver `postgresql` and `skip-verify` for driver `mysql`, 3 set ssl mode to `verify-full` for driver `postgresql` and `preferred` for driver `mysql`
+    - `connectionstring`, string. Provide a custom database connection string. If not empty this connection string will be used instead of build one using the previous parameters. Leave empty for drivers `bolt` and `memory`
+    - `users_table`, string. Database table for SFTP users
+    - `manage_users`, integer. Set to 0 to disable users management, 1 to enable
+    - `track_quota`, integer. Set the preferred mode to track users quota between the following choices:
+        - 0, disable quota tracking. REST API to scan user dir and update quota will do nothing
+        - 1, quota is updated each time a user upload or delete a file even if the user has no quota restrictions
+        - 2, quota is updated each time a user upload or delete a file but only for users with quota restrictions. With this configuration the "quota scan" REST API can still be used to periodically update space usage for users without quota restrictions
+    - `pool_size`, integer. Sets the maximum number of open connections for `mysql` and `postgresql` driver. Default 0 (unlimited)
+    - `users_base_dir`, string. Users' default base directory. If no home dir is defined while adding a new user, and this value is a valid absolute path, then the user home dir will be automatically defined as the path obtained joining the base dir and the username
+    - `actions`, struct. It contains the command to execute and/or the HTTP URL to notify and the trigger conditions. See the "Custom Actions" paragraph for more details
+        - `execute_on`, list of strings. Valid values are `add`, `update`, `delete`. `update` action will not be fired for internal updates such as the last login or the user quota fields.
+        - `command`, string. Absolute path to the command to execute. Leave empty to disable.
+        - `http_notification_url`, a valid URL. Leave empty to disable.
+    - `external_auth_program`, string. Absolute path to an external program to use for users authentication. See the "External Authentication" paragraph for more details.
+    - `external_auth_scope`, integer. 0 means all supported authetication scopes (passwords and public keys). 1 means passwords only. 2 means public keys only
+- **"httpd"**, the configuration for the HTTP server used to serve REST API
+    - `bind_port`, integer. The port used for serving HTTP requests. Set to 0 to disable HTTP server. Default: 8080
+    - `bind_address`, string. Leave blank to listen on all available network interfaces. Default: "127.0.0.1"
+    - `templates_path`, string. Path to the HTML web templates. This can be an absolute path or a path relative to the config dir
+    - `static_files_path`, string. Path to the static files for the web interface. This can be an absolute path or a path relative to the config dir
+    - `backups_path`, string. Path to the backup directory. This can be an absolute path or a path relative to the config dir. We don't allow backups in arbitrary paths for security reasons
+
+Here is a full example showing the default config in JSON format:
+
+```json
+{
+  "sftpd": {
+    "bind_port": 2022,
+    "bind_address": "",
+    "idle_timeout": 15,
+    "max_auth_tries": 0,
+    "umask": "0022",
+    "banner": "",
+    "upload_mode": 0,
+    "actions": {
+      "execute_on": [],
+      "command": "",
+      "http_notification_url": ""
+    },
+    "keys": [],
+    "enable_scp": false,
+    "kex_algorithms": [],
+    "ciphers": [],
+    "macs": [],
+    "login_banner_file": "",
+    "setstat_mode": 0,
+    "enabled_ssh_commands": ["md5sum", "sha1sum", "cd", "pwd"]
+  },
+  "data_provider": {
+    "driver": "sqlite",

+    "templates_path": "templates",
+    "static_files_path": "static",
+    "backups_path": "backups"
+  }
+}
+```
+
+If you want to use a private key that use an algorithm different from RSA or more than one private key then replace the empty `keys` array with something like this:
+
+```json
+"keys": [
+  {
+    "private_key": "id_rsa"
+  },
+  {
+    "private_key": "id_ecdsa"
+  }
+]
+```
+
+The configuration can be read from JSON, TOML, YAML, HCL, envfile and Java properties config files, if your `config-file` flag is set to `sftpgo` (default value) you need to create a configuration file called `sftpgo.json` or `sftpgo.yaml` and so on inside `config-dir`.
+
+You can also override all the available configuration options using environment variables, sftpgo will check for environment variables with a name matching the key uppercased and prefixed with the `SFTPGO_`. You need to use `__` to traverse a struct.
+
+Let's see some examples:
+
+- To set sftpd `bind_port` you need to define the env var `SFTPGO_SFTPD__BIND_PORT`
+- To set the `execute_on` actions you need to define the env var `SFTPGO_SFTPD__ACTIONS__EXECUTE_ON` for example `SFTPGO_SFTPD__ACTIONS__EXECUTE_ON=upload,download`
+
+Please note that to override configuration options with environment variables a configuration file containing the options to override is required. You can, for example, deploy the default configuration file and then override the options you need to customize using environment variables.
+
+To start the SFTP Server with the default values for the command line flags simply use:
+
+```
+sftpgo serve
+```
+
+On Windows you can register `SFTPGo` as Windows Service, take a look at the CLI usage to learn how:
+
+```
+sftpgo.exe service --help
+Install, Uninstall, Start, Stop and retrieve status for SFTPGo Windows Service
+
+Usage:
+  sftpgo service [command]
+
+Available Commands:
+  install     Install SFTPGo as Windows Service
+  start       Start SFTPGo Windows Service
+  status      Retrieve the status for the SFTPGo Windows Service
+  stop        Stop SFTPGo Windows Service
+  uninstall   Uninstall SFTPGo Windows Service
+
+Flags:
+  -h, --help   help for service
+
+Use "sftpgo service [command] --help" for more information about a command.
+```
+
+`install` subcommand accepts the same flags valid for `serve`.
+
+After installing as Windows Service please remember to allow network access to the SFTPGo executable using something like this:
+
+```
+netsh advfirewall firewall add rule name="SFTPGo Service" dir=in action=allow program="C:\Program Files\SFTPGo\sftpgo.exe"
+```
+
+or through the Windows Firewall GUI.
+
+## External Authentication
+
+Custom authentication methods can easily be added. SFTPGo supports external authentication modules, and writing a new backend can be as simple as a few lines of shell script.
+
+To enable external authentication you must set the absolute path of your authentication program using `external_auth_program` key in your configuration file.
+
+The external program can read the following environment variables to get info about the user trying to authenticate:
+
+- `SFTPGO_AUTHD_USERNAME`
+- `SFTPGO_AUTHD_PASSWORD`, not empty for password authentication
+- `SFTPGO_AUTHD_PUBLIC_KEY`, not empty for public key authentication
+
+Previous global environment variables aren't cleared when the script is called. The content of these variables is _not_ quoted. They may contain special characters. They are under the control of a possibly malicious remote user.
+The program must respond on the standard output with a valid SFTPGo user serialized as json if the authentication succeed or an user with an empty username if the authentication fails.
+If the authentication succeed the user will be automatically added/updated inside the defined data provider. Actions defined for user added/updated will not be executed in this case.
+The external program should check authentication only, if there are login restrictions such as user disabled, expired, login allowed only from specific IP addresses it is enough to populate the matching user fields and these conditions will be checked in the same way as for built-in users.
+The external auth program must finish within 15 seconds.
+This method is slower than built-in authentication, but it's very flexible as anyone can easily write his own authentication program.
+You can also restrict the authentication scope for the external program using the `external_auth_scope` configuration key:
+
+- 0 means all supported authetication scopes, the external program will be used for both password and public key authentication
+- 1 means passwords only, the external program will not be used for public key authentication
+- 2 means public keys only, the external program will not be used for password authentication
+
+Let's see a very basic example. Our sample authentication program will only accept user `test_user` with any password or public key.
+
+```
+#!/bin/sh
+
+if test "$SFTPGO_AUTHD_USERNAME" = "test_user"; then
+  echo '{"status":1,"username":"test_user","expiration_date":0,"home_dir":"/tmp/test_user","uid":0,"gid":0,"max_sessions":0,"quota_size":0,"quota_files":100000,"permissions":{"/":["*"],"/somedir":["list","download"]},"upload_bandwidth":0,"download_bandwidth":0,"filters":{"allowed_ip":[],"denied_ip":[]},"public_keys":[]}'
+else
+  echo '{"username":""}'
+fi
+```
+
+If you have an external authentication program that could be useful for others too, for example LDAP/Active Directory authentication, please let us know and/or send a pull request.
+
+## Custom Actions
+
+SFTPGo allows to configure custom commands and/or HTTP notifications on file upload, download, delete, rename, on SSH commands and on user add, update and delete.
+
+The `actions` struct inside the "sftpd" configuration section allows to configure actions on file upload, download, delete, rename and on SSH commands.
+
+Actions will not be executed if an error is detected and so a partial file is uploaded or downloaded or an SSH command is not successfully completed. The `upload` condition includes both uploads to new files and overwrite of existing files. The `ssh_cmd` condition will be triggered after a command is successfully executed via SSH. `scp` will trigger the `download` and `upload` conditions and not `ssh_cmd`.
+
+The `command`, if defined, is invoked with the following arguments:
+
+- `action`, string, possibile values are: `download`, `upload`, `delete`, `rename`, `ssh_cmd`
+- `username`
+- `path` is the full filesystem path, can be empty for some ssh commands
+- `target_path`, non empty for `rename` action
+- `ssh_cmd`, non empty for `ssh_cmd` action
+
+The `command` can also read the following environment variables:
+
+- `SFTPGO_ACTION`
+- `SFTPGO_ACTION_USERNAME`
+- `SFTPGO_ACTION_PATH`
+- `SFTPGO_ACTION_TARGET`, non empty for `rename` `SFTPGO_ACTION`
+- `SFTPGO_ACTION_SSH_CMD`, non empty for `ssh_cmd` `SFTPGO_ACTION`
+- `SFTPGO_ACTION_FILE_SIZE`, non empty for `upload`, `download` and `delete` `SFTPGO_ACTION`
+
+Previous global environment variables aren't cleared when the script is called.
+The `command` must finish within 30 seconds.
+
+The `http_notification_url`, if defined, will contain the following, percent encoded, query string parameters:
+
+- `action`
+- `username`
+- `path`
+- `target_path`, added for `rename` action
+- `ssh_cmd`, added for `ssh_cmd` action
+- `file_size`, added for `upload`, `download`, `delete` actions
+
+The HTTP request has a 15 seconds timeout.
+
+The `actions` struct inside the "data_provider" configuration section allows to configure actions on user add, update, delete.
+
+Actions will not be fired for internal updates such as the last login or the user quota fields or after external authentication.
+
+The `command`, if defined, is invoked with the following arguments:
+
+- `action`, string, possibile values are: `add`, `update`, `delete`
+- `username`
+- `ID`
+- `status`
+- `expiration_date`
+- `home_dir`
+- `uid`
+- `gid`
+
+The `command` can also read the following environment variables:
+
+- `SFTPGO_USER_ACTION`
+- `SFTPGO_USER_USERNAME`
+- `SFTPGO_USER_ID`
+- `SFTPGO_USER_STATUS`
+- `SFTPGO_USER_EXPIRATION_DATE`
+- `SFTPGO_USER_HOME_DIR`
+- `SFTPGO_USER_UID`
+- `SFTPGO_USER_GID`
+
+Previous global environment variables aren't cleared when the script is called.
+The `command` must finish within 15 seconds.
+
+The `http_notification_url`, if defined, will be called invoked as http POST. The action is added to the query string, for example `<http_notification_url>?action=update` and the user is sent serialized as json inside the POST body
+
+The HTTP request has a 15 seconds timeout.
+
+## Portable mode
+
+SFTPGo allows to share a single directory on demand using the `portable` subcommand:
+
+```
+sftpgo portable --help
+To serve the current working directory with auto generated credentials simply use:
+
+sftpgo portable
+
+Please take a look at the usage below to customize the serving parameters
+
+Usage:
+  sftpgo portable [flags]
+
+Flags:
+  -C, --advertise-credentials   If the SFTP service is advertised via multicast DNS this flag allows to put username/password inside the advertised TXT record
+  -S, --advertise-service       Advertise SFTP service using multicast DNS (default true)
+  -d, --directory string        Path to the directory to serve. This can be an absolute path or a path relative to the current directory (default ".")
+  -h, --help                    help for portable
+  -l, --log-file-path string    Leave empty to disable logging
+  -p, --password string         Leave empty to use an auto generated value
+  -g, --permissions strings     User's permissions. "*" means any permission (default [list,download])
+  -k, --public-key strings
+  -s, --sftpd-port int          0 means a random non privileged port
+  -c, --ssh-commands strings    SSH commands to enable. "*" means any supported SSH command including scp (default [md5sum,sha1sum,cd,pwd])
+  -u, --username string         Leave empty to use an auto generated value
+```
+
+In portable mode SFTPGo can advertise the SFTP service and, optionally, the credentials via multicast DNS, so there is a standard way to discover the service and to automatically connect to it.
+
+Here is an example of the advertised service including credentials as seen using `avahi-browse`:
+
+```
+= enp0s31f6 IPv4 SFTPGo portable 53705                         SFTP File Transfer   local
+   hostname = [p1.local]
+   address = [192.168.1.230]
+   port = [53705]
+   txt = ["password=EWOo6pJe" "user=user" "version=0.9.3-dev-b409523-dirty-2019-10-26T13:43:32Z"]
+```
+
+## Account's configuration properties
+
+For each account the following properties can be configured:
+
+- `username`
+- `password` used for password authentication. For users created using SFTPGo REST API if the password has no known hashing algo prefix it will be stored using argon2id. SFTPGo supports checking passwords stored with bcrypt, pbkdf2, md5crypt and sha512crypt too. For pbkdf2 the supported format is `$<algo>$<iterations>$<salt>$<hashed pwd base64 encoded>`, where algo is `pbkdf2-sha1` or `pbkdf2-sha256` or `pbkdf2-sha512`. For example the `pbkdf2-sha256` of the word `password` using 150000 iterations and `E86a9YMX3zC7` as salt must be stored as `$pbkdf2-sha256$150000$E86a9YMX3zC7$R5J62hsSq+pYw00hLLPKBbcGXmq7fj5+/M0IFoYtZbo=`. For bcrypt the format must be the one supported by golang's [crypto/bcrypt](https://godoc.org/golang.org/x/crypto/bcrypt) package, for example the password `secret` with cost `14` must be stored as `$2a$14$ajq8Q7fbtFRQvXpdCq7Jcuy.Rx1h/L4J60Otx.gyNLbAYctGMJ9tK`. For md5crypt and sha512crypt we support the format used in `/etc/shadow` with the `$1$` and `$6$` prefix, this is useful if you are migrating from Unix system user accounts.  Using the REST API you can send a password hashed as bcrypt, pbkdf2, md5crypt or sha512crypt and it will be stored as is.
+- `public_keys` array of public keys. At least one public key or the password is mandatory.
+- `status` 1 means "active", 0 "inactive". An inactive account cannot login.
+- `expiration_date` expiration date as unix timestamp in milliseconds. An expired account cannot login. 0 means no expiration.
+- `home_dir` The user cannot upload or download files outside this directory. Must be an absolute path.
+- `uid`, `gid`. If sftpgo runs as root system user then the created files and directories will be assigned to this system uid/gid. Ignored on windows and if sftpgo runs as non root user: in this case files and directories for all SFTP users will be owned by the system user that runs sftpgo.
+- `max_sessions` maximum concurrent sessions. 0 means unlimited.
+- `quota_size` maximum size allowed as bytes. 0 means unlimited.
+- `quota_files` maximum number of files allowed. 0 means unlimited.
+- `permissions` the following per directory permissions are supported:
+    - `*` all permissions are granted
+    - `list` list items is allowed
+    - `download` download files is allowed
+    - `upload` upload files is allowed
+    - `overwrite` overwrite an existing file, while uploading, is allowed. `upload` permission is required to allow file overwrite
+    - `delete` delete files or directories is allowed
+    - `rename` rename files or directories is allowed
+    - `create_dirs` create directories is allowed
+    - `create_symlinks` create symbolic links is allowed
+    - `chmod` changing file or directory permissions is allowed. On Windows, only the 0200 bit (owner writable) of mode is used; it controls whether the file's read-only attribute is set or cleared. The other bits are currently unused. Use mode 0400 for a read-only file and 0600 for a readable+writable file.
+    - `chown` changing file or directory owner and group is allowed. Changing owner and group is not supported on Windows.
+    - `chtimes` changing file or directory access and modification time is allowed
+- `upload_bandwidth` maximum upload bandwidth as KB/s, 0 means unlimited.
+- `download_bandwidth` maximum download bandwidth as KB/s, 0 means unlimited.
+- `allowed_ip`, List of IP/Mask allowed to login. Any IP address not contained in this list cannot login. IP/Mask must be in CIDR notation as defined in RFC 4632 and RFC 4291, for example "192.0.2.0/24" or "2001:db8::/32"
+- `denied_ip`, List of IP/Mask not allowed to login. If an IP address is both allowed and denied then login will be denied
+
+These properties are stored inside the data provider.
+
+If you want to use your existing accounts you have these options:
+
+- If your accounts are aleady stored inside a supported database, you can create a database view. Since a view is read only, you have to disable user management and quota tracking so SFTPGo will never try to write to the view
+- you can import your users inside SFTPGo. Take a look at [sftpgo_api_cli.py](./scripts/README.md "sftpgo_api_cli script"), it can convert and import users from Linux system users and Pure-FTPd/ProFTPD virtual users
+- you can use an external authentication program
+
+## REST API
+
+SFTPGo exposes REST API to manage, backup and restore users and to get real time reports of the active connections with possibility of forcibly closing a connection.
+
+If quota tracking is enabled in `sftpgo` configuration file, then the used size and number of files are updated each time a file is added/removed. If files are added/removed not using SFTP/SCP or if you change `track_quota` from `2` to `1`, you can rescan the users home dir and update the used quota using the REST API.
+
+REST API is designed to run on localhost or on a trusted network, if you need HTTPS and/or authentication you can setup a reverse proxy using an HTTP Server such as Apache or NGNIX.
+
+For example you can keep SFTPGo listening on localhost and expose it externally configuring a reverse proxy using Apache HTTP Server this way:
+
+```
+ProxyPass /api/v1 http://127.0.0.1:8080/api/v1
+ProxyPassReverse /api/v1 http://127.0.0.1:8080/api/v1
+```
+
+and you can add authentication with something like this:
+
+```
+<Location /api/v1>
+	AuthType Digest
+	AuthName "Private"
+	AuthDigestDomain "/api/v1"
+	AuthDigestProvider file
+	AuthUserFile "/etc/httpd/conf/auth_digest"
+	Require valid-user
+</Location>
+```
+
+and, of course, you can configure the web server to use HTTPS.
+
+The OpenAPI 3 schema for the exposed API can be found inside the source tree: [openapi.yaml](./httpd/schema/openapi.yaml "OpenAPI 3 specs").
+
+A sample CLI client for the REST API can be found inside the source tree [scripts](./scripts "scripts") directory.
+
+You can also generate your own REST client, in your preferred programming language or even bash scripts, using an OpenAPI generator such as [swagger-codegen](https://github.com/swagger-api/swagger-codegen) or [OpenAPI Generator](https://openapi-generator.tech/)
+
+## Metrics
+
+SFTPGo exposes [Prometheus](https://prometheus.io/) metrics at the `/metrics` HTTP endpoint.
+Several counters and gauges are available, for example:
+
+- Total uploads and downloads
+- Total upload and download size
+- Total upload and download errors
+- Total executed SSH commands
+- Total SSH command errors
+- Number of active connections
+- Data provider availability
+- Total successful and failed logins using a password or a public key
+- Total HTTP requests served and totals for response code
+- Go's runtime details about GC, number of gouroutines and OS threads
+- Process information like CPU, memory, file descriptor usage and start time
+
+Please check the `/metrics` page for more details.
+
+## Web Admin
+
+You can easily build your own interface using the exposed REST API, anyway SFTPGo provides also a very basic built-in web interface that allows to manage users and connections.
+With the default `httpd` configuration, the web admin is available at the following URL:
+
+[http://127.0.0.1:8080/web](http://127.0.0.1:8080/web)
+
+If you need HTTPS and/or authentication you can setup a reverse proxy as explained for the REST API.
+
+## Logs
+
+Inside the log file each line is a JSON struct, each struct has a `sender` fields that identify the log type.
+
+The logs can be divided into the following categories:
+
+- **"app logs"**, internal logs used to debug `sftpgo`:
+    - `sender` string. This is generally the package name that emits the log
+    - `time` string. Date/time with millisecond precision
+    - `level` string
+    - `message` string
+- **"transfer logs"**, SFTP/SCP transfer logs:

+### Brute force protection
+
+The **connection failed logs** can be used for integration in tools such as [Fail2ban](http://www.fail2ban.org/). Example of [jails](./fail2ban/jails) and [filters](./fail2ban/filters) working with `systemd`/`journald` are available in fail2ban directory.

-# Security Policy
-
-## Supported Versions
-
-We actively maintain the latest stable release of SFTPGo. While we strive to keep the Open Source version secure and up-to-date, maintenance is performed on a best-effort basis by the community and contributors.
-
-## Scope and Dependency Policy
-
-Our security advisories focus on vulnerabilities found within the **SFTPGo codebase itself**.
-
-To ensure the long-term sustainability of the project, we handle upstream dependencies (like the Go standard library, external packages, or Docker base images) as follows:
-
-- Community Updates: For the Open Source version, vulnerabilities in upstream components (such as the Go standard library or third-party packages) are addressed during our **regular release cycles**. We generally do not provide immediate, out-of-band or ad-hoc releases to address dependency-only CVEs.
-- Empowering Users: One of the strengths of SFTPGo being open-source is that you have full control. If your security scanners require an immediate fix, you can always rebuild the project using the latest patched Go toolchain or updated dependencies.
-- Compatibility: We are committed to keeping SFTPGo compatible with the latest stable Go compiler. If an upstream fix breaks SFTPGo, fixing that becomes a priority for us.
-- Professional Needs: We understand that some organizations have strict compliance requirements or internal SLAs that require guaranteed, immediate response times and out-of-band patches. For these cases, we offer [SFTPGo Enterprise](https://sftpgo.com/on-premises) to cover the additional maintenance and support overhead.
-
-## Reporting a Vulnerability
-
-To report (possible) security issues in SFTPGo, please either send a mail to the [SFTPGo Team](mailto:support@sftpgo.com) or use Github's [private reporting feature](https://github.com/drakkan/sftpgo/security/advisories/new).

+## Dockerfile based on Debian stable
+
+Please read the comments inside the `Dockerfile` to learn how to customize things for your setup.
+
+You can build the container image using `docker build`, for example:
+
+```bash
+docker build -t="drakkan/sftpgo" .
+```
+
+and you can run the Dockerfile using something like this:
+
+```bash
+docker run --name sftpgo -p 8080:8080 -p 2022:2022 --mount type=bind,source=/srv/sftpgo/data,target=/app/data --mount type=bind,source=/srv/sftpgo/config,target=/app/config --mount type=bind,source=/srv/sftpgo/backups,target=/app/backups drakkan/sftpgo
+```
+
+where  `/srv/sftpgo/data`, `/srv/sftpgo/config` and `/srv/sftpgo/backups` are folders on the host system with write access for UID/GID defined inside the `Dockerfile`. You can choose to create a new user, on the host system, with a matching UID/GID pair or simply do something like:
+
+
+```bash
+chown -R <UID>:<GID> /srv/sftpgo/data /srv/sftpgo/config /srv/sftpgo/backups

-# Authy
-
-These example show how-to integrate [Twilio Authy API](https://www.twilio.com/docs/authy/api) for One-Time-Password logins.
-
-The examples assume that the user has the free [Authy app](https://authy.com/) installed and uses it to generate offline [TOTP](https://en.wikipedia.org/wiki/Time-based_One-time_Password_algorithm) codes (soft tokens).
-
-You first need to [create an Authy Application in the Twilio Console](https://twilio.com/console/authy/applications?_ga=2.205553366.451688189.1597667213-1526360003.1597667213), then you can create a new Authy user and store a reference to the matching SFTPGo account.
-
-Verify that your Authy application is successfully registered:
-
-```bash
-export AUTHY_API_KEY=<your api key here>
-curl 'https://api.authy.com/protected/json/app/details' -H "X-Authy-API-Key: $AUTHY_API_KEY"
-```
-
-now create an Authy user:
-
-```bash
-curl -XPOST "https://api.authy.com/protected/json/users/new" \
--H "X-Authy-API-Key: $AUTHY_API_KEY" \
---data-urlencode user[email]="user@domain.com" \
---data-urlencode user[cellphone]="317-338-9302" \
---data-urlencode user[country_code]="54"
-```
-
-The response is something like this:
-
-```json
-{"message":"User created successfully.","user":{"id":xxxxxxxx},"success":true}
-```
-
-Save the user id somewhere and add a reference to the matching SFTPGo account. You could also store this ID in the `additional_info` SFTPGo user field.
-
-After this step you can use the Authy app installed on your phone to generate TOTP codes.
-
-Now you can verify the token using an HTTP GET request:
-
-```bash
-export TOKEN=<TOTP you read from Authy app>
-export AUTHY_ID=<user id>
-curl -i "https://api.authy.com/protected/json/verify/${TOKEN}/${AUTHY_ID}" \
-    -H "X-Authy-API-Key: $AUTHY_API_KEY"
-```
-
-So inside your hook you need to check:
-
-- the HTTP response code for the verify request, it must be `200`
-- the JSON response body, it must contains the key `success` with the value `true` (as string)
-
-If these conditions are met the token is valid and you allow the user to login.
-
-We provide the following examples:
-
-- [Keyboard interactive authentication](./keyint/README.md) for 2FA using password + Authy one time token.
-- [External authentication](./extauth/README.md) using Authy one time tokens as passwords.
-- [Check password hook](./checkpwd/README.md) for 2FA using a password consisting of a fixed string and a One Time Token.
-
-Please note that these are sample programs not intended for production use, you should write your own hook based on them and you should prefer HTTP based hooks if performance is a concern.
-
-:warning: SFTPGo has also built-in 2FA support.

-# Import users from other stores
-
-`convertusers` is a very simple command line client, written in python, to import users from other stores. It requires `python3` or `python2`.
-
-Here is the usage:
-
-```console
-usage: convertusers [-h] [--min-uid MIN_UID] [--max-uid MAX_UID] [--usernames USERNAMES [USERNAMES ...]]
-                    [--force-uid FORCE_UID] [--force-gid FORCE_GID]
-                    input_file {unix-passwd,pure-ftpd,proftpd} output_file
-
-Convert users to a JSON format suitable to use with loadddata
-
-positional arguments:
-  input_file
-  {unix-passwd,pure-ftpd,proftpd}
-                        To import from unix-passwd format you need the permission to read /etc/shadow that is typically
-                        granted to the root user only
-  output_file
-
-optional arguments:
-  -h, --help            show this help message and exit
-  --min-uid MIN_UID     if >= 0 only import users with UID greater or equal to this value. Default: -1
-  --max-uid MAX_UID     if >= 0 only import users with UID lesser or equal to this value. Default: -1
-  --usernames USERNAMES [USERNAMES ...]
-                        Only import users with these usernames. Default: []
-  --force-uid FORCE_UID
-                        if >= 0 the imported users will have this UID in SFTPGo. Default: -1
-  --force-gid FORCE_GID
-                        if >= 0 the imported users will have this GID in SFTPGo. Default: -1
-```
-
-Let's see some examples:
-
-```console
-python convertusers "" unix-passwd unix_users.json --min-uid 500 --force-uid 1000 --force-gid 1000
-```
-
-```console
-python convertusers pureftpd.passwd pure-ftpd pure_users.json --usernames "user1" "user2"
-```
-
-```console
-python convertusers proftpd.passwd proftpd pro_users.json
-```
-
-The generated json file can be used as input for the `loaddata` REST API.
-
-Please note that when importing Linux/Unix users the input file is not required: `/etc/passwd` and `/etc/shadow` are automatically parsed. `/etc/shadow` read permission is typically granted to the `root` user only, so you need to execute `convertusers` as `root`.
-
-:warning: SFTPGo does not currently support `yescrypt` hashed passwords.

-# LDAPAuth
-
-This is an example for an external authentication program. It performs authentication against an LDAP server.
-It is tested against [389ds](https://directory.fedoraproject.org/) and can be used as starting point to authenticate using any LDAP server including Active Directory.
-
-You need to change the LDAP connection parameters and the user search query to match your environment.
-You can build this example using the following command:
-
-```console
-go build -ldflags "-s -w" -o ldapauth
-```
-
-This program assumes that the 389ds schema was extended to add support for public keys using the following ldif file placed in `/etc/dirsrv/schema/98openssh-ldap.ldif`:

-# LDAPAuthServer
-
-This is an example for an HTTP server to use as external authentication HTTP hook. It performs authentication against an LDAP server.
-It is tested against [389ds](https://directory.fedoraproject.org/) and can be used as starting point to authenticate using any LDAP server including Active Directory.
-
-You can configure the server using the [ldapauth.toml](./ldapauth.toml) configuration file.
-You can build this example using the following command:
-
-```console
-go build -ldflags "-s -w" -o ldapauthserver
-```
-
-:warning: A plugin for LDAP/Active Directory authentication is also [available](https://github.com/sftpgo/sftpgo-plugin-auth).

-# SFTPGo on Windows with Active Directory Integration + Caddy Static File Server Example
-
-[![SFTPGo on Windows with Active Directory Integration + Caddy Static File Server Example](https://img.youtube.com/vi/M5UcJI8t4AI/0.jpg)](https://www.youtube.com/watch?v=M5UcJI8t4AI)
-
-This is similar to the ldapauthserver example, but is more specific to using Active Directory along with using SFTPGo on a Windows Server.
-
-The Youtube Walkthrough/Tutorial video above goes into considerable more detail, but in short, it walks through setting up SFTPGo on a new Windows Server, and enables the External Authentication feature within SFTPGo, along with my `sftpgo-ldap-http-server` project, to allow for user authentication into SFTPGo to occur through one or more Active Directory connections.
-
-Additionally, I go through using the Caddy web server, to help enable serving of static files, if this is something that would be of interest for you.
-
-To get started, you'll want to download the latest release ZIP package from the [sftpgo-ldap-http-server repository](https://github.com/orware/sftpgo-ldap-http-server).
-
-The ZIP itself contains the `sftpgo-ldap-http-server.exe` file, along with an `OpenLDAP` folder (mainly to help if you want to use TLS for your LDAP connections), and a `Data` which contains a logs folder, a configuration.example.php file, a functions.php file, and the LICENSE and README files.
-
-The video above goes through the whole process, but to get started you'll want to install SFTPGo on your server, and then extract the `sftpgo-ldap-http-server` ZIP file on the server as well into a separate folder. Then you'll want to copy the configuration.example.php file and name it `configuration.php` and begin customizing the settings (e.g. add in your own LDAP settings, along with how you may want to have your folders be created). At the very minimum you'll want to make sure that the home directories are set correctly to how you want the folders to be created for your environment (you don't have to use the virtual folders or really any of the other functionality if you don't need it).
-
-Once configured, from a command prompt window, if you are already in the same folder as where you extracted the `sftpgo-ldap-http-server` ZIP, you may simply call the `sftpgo-ldap-http-server.exe` and it should start up a simple HTTP server on Port 9001 running on localhost (the port can be adjusted via the `configuration.php` file as well). Now all you have to do is point SFTPGo's `external_auth_hook` option to point to `http://localhost:9001/` and you should be able to run some authentication tests (assuming you have all of your settings correct and there are no intermediate issues).
-
-The video above definitely goes through some troubleshooting situations you might find yourself coming across, so while it is long (at about 1 hour, 42 minutes), it may be helpful to review and avoid some issues and just to learn a bit more about SFTPGo and the integration above.
-
-## Example Virtual Folders Configuration (Allowing for Both a Public and Private Folder)
-
-The following can be utilized if you'd like to assign your users both a Private Virtual Folder and Public Virtual Folder.
-
-By itself, the Public Virtual Folder isn't necessarily public, so keep that in mind. Only by combining things together with the Caddy web server (and Caddyfile example configuration down below) can you be successful in making the `F:\files\public` folder from the example public.
-
-```php

-## Example Connection "Output Object" Allowing For No Files in the User's Home Directory ("Root Directory") but Allowing for Files in the Public/Private Virtual Folders
-
-The magic here happens in the "permissions" value, by limiting the root/home directory to just the list/download permissions, and then allowing all permissions on the Public/Private virtual folders.
-
-```php
-$connection_output_objects['example'] = [
-    'status' => 1,

-## Recommended Usage of Automatic Groups Mode (Limiting by Group Prefix)
-
-The `sftpgo-ldap-http-server` project is able to automatically create virtual folders for any groups your user is a memberof if the automatic mode is turned on. However, by having a specific set of allowed prefixes defined, you can limit things to just those groups that begin with the prefixes you've listed, which can be helpful. The prefix itself will be removed from the group name when added as a virtual folder for the user.
-
-```php
-// If automatic groups mode is disabled, then you have to manually add the allowed groups into $allowed_groups down below:
-// If enabled, then any groups you are a memberof will automatically be added in using the template below.
-$auto_groups_mode = true;

-    [
-      //"id" => 0,

-      //"used_quota_size" => 0,
-      //"used_quota_files" => 0,
-      //"last_quota_update" => 0,
-      "virtual_path" => "/groups/#GROUP#",
-      "quota_size" => 0,
-      "quota_files" => 100000
-    ]
-];
-
-// Used only when auto groups mode is enabled and will help prevent all your groups from being
-// added into SFTPGo since only groups with the prefixes defined here will be automatically added
-// with prefixes automatically removed when listed as a virtual folder (e.g. a group with name
-// "sftpgo-example" would simply become "example").
-$allowed_group_prefixes = [

-# Update user quota
-
-:warning: Since v2.4.0 you can use the [EventManager](https://docs.sftpgo.com/latest/eventmanager/) to schedule quota scans.
-
-The `scanuserquota` example script shows how to use the SFTPGo REST API to update the users' quota.
-
-The stored quota may be incorrect for several reasons, such as an unexpected shutdown while uploading files, temporary provider failures, files copied outside of SFTPGo, and so on.
-
-A quota scan updates the number of files and their total size for the specified user and the virtual folders, if any, included in his quota.
-
-If you want to track quotas, a scheduled quota scan is recommended. You can use this example as a starting point.
-
-The script is written in Python and has the following requirements:
-
-- python3 or python2
-- python [Requests](https://requests.readthedocs.io/en/master/) module
-
-The provided example tries to connect to an SFTPGo instance running on `127.0.0.1:8080` using the following credentials:
-
-- username: `admin`
-- password: `password`
-
-Please edit the script according to your needs.
