• Ldap server e.g. ldap://ldap.mydomain.com: ldap://ldap.mydomain.com
• Port number (default when omitted is 389): (389 or leave blank)
• LDAP version (LDAPv2 = 2), e.g. 3: LDAPv3
• Select true if referrals must be followed (use false for ActiveDirectory): (leave blank)
• Check to enable Start-TLS encryption When using LDAPv3: False
• Select how to perform authentication: Search and bind
• Attribute to compare to the given login can be uid, cn, mail, ...: uid
• Base DN for the user search operation: ou=people,dc=mydomain,dc=com
• Optional extra LDAP filter to be ANDed to the basic (searchuserattribute=username) filter. Don't forget the outmost enclosing parentheses: (leave blank)
• Optional DN of the LDAP account used to search for the end-user's DN. An anonymous bind is performed if empty.: cn=admin,dc=mydomain,dc=com
• Password of the LDAP account used to search for the end-user's DN if previoulsy set.: password (appears!)
• Check to make default authentication method: (as you wish)

Log in using the LDAP credentials (username: user and password).

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 Groups OU that includes an entry identified by cn=limeusers and our policy is that for a user to be authorized to use LimeSurvey that entry must include an attribute of the form memberUid=username 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: ou=Groups,dc=mydomain,dc=com
• Optional filter for group restriction: (&(cn=limeusers)(memberUid=$username))

Note:

1. $username is a magic value (in the context of the filter parameter) that is replaced by the username entered by the user when logging in.
2. 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.
3. Before specifying a group restriction this way, verify that basic LDAP authentication is working correctly.
4. If either of the group restriction parameters is empty then the group restriction step will not be applied.
