question: dynamic groups / reverse group membership



Hello,

one question about dynamic groups.

Explanation:

I think the configuration of dynamic groups is more flexible than the static method (memberof). I can create any ldapserch to get a list depending on all kind of attributes or objectclasses. If I configure the reverse group membership overlay I have to use the dn of the group and the dn of the entry. To change the objectclasses on which the memberof attribute depends or change the attribute name on which the dn depends is possible, but thats it.

Example (static):
dn: cn=testgroup,ou=Groups,dc=example
uniqueMember: uid=testuser,ou=People,dc=example
...

dn: uid=testuser,ou=People,dc=example
memberOf: cn=testgroup,ou=Groups,dc=example
...

In that example the configuration is for both sides. If I add a Member to cn=testgroup the memberOf is add to uid=testuser and if I add a Group to uid=testuser the uniqueMember is add to cn=testgroup.

Example (dynamic):
dn: cn=testgroup,ou=Groups,dc=example
labeldURI: ldap:///ou=people,dc=example??one?(&(objectclass=person)(departmentNumber=test))
uniqueMember: uid=testuser,ou=People,dc=example
...

dn: uid=testuser,ou=People,dc=example
departmentNumber: test
...

In that example the group attribute (departementNumber) is mapped to a specific groupname (cn).

With static groups I can do a search like that:
ldapsearch -h ldap -b dc=example '(uniquemember=uid=testuser,ou=People,dc=example)' dn

With dynamic groups the search result is empty because the entry (uniquemember) doesn't exists in the underlying DB.

Question:

Is it possible to copy/configure the behavior from dynamic groups to reverse group membership? I have some applications that use searches with '(uniquemember=uid={uid},dc=example)'. These applications need the static entries.
