LDAP - user per group is working - groups per user didn´t work


i am using IBM Domino as LDAP backend system.

It was easy to get the user and the groups frpm LDAP.

When i open a group it also shows the users, that are inside this group.

But on the users list it doesn´t shows the groups this user belongs to.

I think that it has something to do with the organisation of the domino LDAP.

Getting all user within a group works with objectclass groupOfNames and the member attribute.

Getting all groups of a user needs objectclass dominoAccessGroups and the attribute CN.

Has somebody an idea how to resolve this issue?

Kind regards
