Jonathan Sambrook 878ac0d192 Filter user loading at startup for "advanced" LDAP
Users are loaded at startup. Currently when using "advanced" LDAP
authentication this is true even if they no longer have a
valid entry in the LDAP server.

This commit uses the existing LDAP filter (specified in config.js's searchDN
used by the "advanced" LDAP mechanism) to weed out any users that no
longer have the relevant LDAP entry.

Local and "simple" LDAP auth mechanisms continue to use the existing
load all users approach. In the "simple" LDAP case this is because we
only have access to the hashed password, and so can't bind to LDAP.
