==== Authentication with OpenLDAP, ''uid'' attribute, and group restriction [2.62+] ====
 
Some applications require a separate LDAP query (beyond the user search and bind to check password) to determine if the user has sufficient authorization. For example, let's assume that LDAP has a <code>Groups</code> OU that includes an entry identified by <code>cn=limeusers</code> and our policy is that for a user to be authorized to use LimeSurvey that entry must include an attribute of the form <code>memberUid=<i>username</i></code> where ''username'' is the username (uid) entered by the user attempting to login. To configure LDAP for that, set up basic ''uid'' authentication as above and then set the following additional (optional) parameters:
 
* ''Optional base DN for group restriction'': <code>ou=Groups,dc=mydomain,dc=com</code>
* ''Optional filter for group restriction'': <code>(&(cn=limeusers)(memberUid=$username))</code>
 
Note:
# <code>$username</code> is a magic value (in the context of the filter parameter) that is replaced by the username entered by the user when logging in.
# Although intended for testing group membership as above, this optional "group restriction" capability can be used to add any authorization check that can be expressed as a separate filtered search like this.
# Before specifying a group restriction this way, verify that basic LDAP authentication is working correctly.
# If either of the group restriction parameters is empty then the group restriction step will not be applied.
