title: Is there an LDAP standard group membership attribute for users?
body: <p>I'm currently working on an application which uses LDAP as an authentication method. I was wondering if the <code>LDAP</code> protocol has a standard membership attribute which would hold the user's group? So far <code>memberOf</code> is working in <code>OpenLDAP</code> and <code>Active Direcotry</code> but not in <code>Apache DS</code>. I couldn't find this attribute in the RFCs so I'm kind of confused. Should I be using the <code>memberOf</code> attribute or I need to go the old fashion way traversing over all of the groups to find which group has the <code>member</code>?</p>
