Has anyone else configured their ldap to use this field from an exchange server. $LDAPServers['xx'] = new LDAPServer('xx', '--', 'x.x.x.x', '', 'sn', WHAT GOES HERE--> '???,cn,mail,sn,givenname', 'is,is_strict,contains,begins,ends'); The server works, but I cannot see the exchange distribution lists. Thanks in advance. Chris
