-- Go as build only dependency. We support the Go version(s) used in [continuous integration workflows](./tree/main/.github/workflows).
-- A suitable SQL server to use as data provider: PostgreSQL 9.4+ or MySQL 5.6+ or SQLite 3.x or CockroachDB stable.

The SFTPGo web client allows to send the files with the specified extensions to the configured URL using the [postMessage API](https://developer.mozilla.org/en-US/docs/Web/API/Window/postMessage). This way you can integrate your own file viewer or editor. Take a look at the commentented example [here](../examples/webclient-integrations/test.html) to understand how to use this feature. Each struct has the following fields:
       - `file_extensions`, list of strings. File extensions must be specified with the leading dot, for example `.pdf`.
       - `url`, string. URL to open for the configured file extensions. The url will open in a new tab.

+      - `client_secret`, string. Defines the application's secret. Default: blank.
+      - `redirect_base_url`, string. Defines the base URL to redirect to after OpenID authentication. The suffix `/web/oidc/redirect` will be added to this base URL, adding also the `web_root` if configured. Default: blank.
+      - `username_field`, string. Defines the ID token claims field to map to the SFTPGo username. Default: blank.
+      - `role_field`, string. Defines the optional ID token claims field to map to a SFTPGo role. If the defined ID token claims field is set to `admin` the authenticated user is mapped to an SFTPGo admin. You don't need to specify this field if you want to use OpenID only for the Web Client UI.

+# OpenID Connect
+
+OpenID Connect integration allows you to map your identity provider users to SFTPGo admins/users and so you can login to SFTPGo Web Client and Web Admin user interfaces using your identity provider.
+
+SFTPGo allows to configure per-binding OpenID Connect configurations. The supported configuration parameters are documented within the `oidc` section [here](./full-configuration.md).
+
+Let's see a basic integration with the [Keycloak](https://www.keycloak.org/) identify provider. Other OpenID connect compatible providers should work by configuring them in a similar way.
+
+We'll not go through the complete process of creating a realm/clients/users in Keycloak. You can look this up [here](https://www.keycloak.org/docs/latest/server_admin/index.html#admin-console).
+
+Here is just an outline:
+
+- create a realm named `sftpgo`
+- in "Realm Settings" -> "Login" adjust the "Require SSL" setting as per your requirements
+- create a client named `sftpgo-client`
+- for the `sftpgo-client` set the `Access Type` to `confidential` and a valid redirect URI, for example if your SFTPGo instance is running on `http://192.168.1.50:8080` a valid redirect URI is `http://192.168.1.50:8080/*`
+- for the `sftpgo-client`, in the `Mappers` settings, make sure that the username and the sftpgo role are added to the ID token. For example you can add the user attribute `sftpgo_role` as JSON string to the ID token and the `username` as `preferred_username` JSON string to the ID token
+- for your users who need to be mapped as SFTPGo administrators add a custom attribute specifying `sftpgo_role` as key and `admin` as value
+
+The resulting JSON configuration for the `sftpgo-client` that you can obtain from the "Installation" tab is something like this:
+
+```json
+{
+  "realm": "sftpgo",
+  "auth-server-url": "http://192.168.1.12:8086/auth/",
+  "ssl-required": "none",
+  "resource": "sftpgo-client",
+  "credentials": {
+    "secret": "jRsmE0SWnuZjP7djBqNq0mrf8QN77j2c"
+  },
+  "confidential-port": 0
+}
+```
+
+Add the following configuration parameters to the SFTPGo configuration file (or use env vars to set them):
+
+```json
+...
+    "oidc": {
+      "client_id": "sftpgo-client",
+      "client_secret": "jRsmE0SWnuZjP7djBqNq0mrf8QN77j2c",
+      "config_url": "http://192.168.1.12:8086/auth/realms/sftpgo",
+      "redirect_base_url": "http://192.168.1.50:8080",
+      "username_field": "preferred_username",
+      "role_field": "sftpgo_role"
+    }
+...
+```
+
+From SFTPGo login page click `Login with OpenID` button, you will be redirected to the Keycloak login page, after a successful authentication Keyclock will redirect back to SFTPGo Web Admin or SFTPGo Web Client.
+
+Please note that the ID token returned from Keycloak must contain the `username_field` specified in the SFTPGo configuration and optionally the `role_field`. The mapped usernames must exist in SFTPGo.
+
+Here is an example ID token which allows the SFTPGo admin `root` to access to the Web Admin UI.
+
+```json
+{
+    "exp": 1644758026,
+    "iat": 1644757726,
+    "auth_time": 1644757647,
+    "jti": "c6cf172d-08d6-41cf-8e5d-20b7ac0b8011",
+    "iss": "http://192.168.1.12:8086/auth/realms/sftpgo",
+    "aud": "sftpgo-client",
+    "sub": "48b0de4b-3090-4315-bbcb-be63c48be1d2",
+    "typ": "ID",
+    "azp": "sftpgo-client",

+    "acr": "0",
+    "sid": "e20ab97c-d3a9-4e53-872d-09d104cbd286",
+    "email_verified": false,
+    "preferred_username": "root",
+    "sftpgo_role": "admin"
+}
+```
+
+And the following is an example ID token which allows the SFTPGo user `user1` to access to the Web Client UI.
+
+```json
+{
+    "exp": 1644758183,
+    "iat": 1644757883,
