MemberOf Attribute DirX

Hi LDAP Folks,

In Active Directory there is the built-in attribute 'memberOf'. It gives you all the groups a user is assigned to. In IBM Tivoli there is a similar thing named 'ibm-allgroups'.

Now there is the Siemens DirX LDAP directory. Does anybody know whether there is a similar animal like memberOf?

The group entries have got a multi-valued attribute 'member'. It holds all the users assigned to the group.
Unfortunately the user entries got no attributes with the group names.

Thanks
