Thread:Extension talk:LDAP Authentication/problem configuring group membership check

Hello everyone,

I'm running MediaWiki 1.21.1 with LdapAuthentication 2.0d (2012-11-21). The authentication against the ldap server works well. Now I want authenticate only users of a special group. I'm not the administrator of the ldap server i used for authentication. The group membership is an attribute of the user and not a organisation unit the user is a member of.

Here are all informations for the user smith from the ldap server:

dn: uid=smith,ou=active,ou=people,dc=my-company,dc=org objectClass: top objectClass: person objectClass: organizationalPerson objectClass: inetOrgPerson objectClass: hisPerson objectClass: fhfPerson objectClass: posixAccount objectClass: shadowAccount objectClass: sambaSamAccount objectClass: inetLocalMailRecipient uid: smith gidNumber: 123

and here my configuration to use ldap authentication:

Please, can you help me to complete my configuration to authenticate user with gidNumber: 123?

thank you
