Member of nested groups of different classes

Dear All,

some users are member of a groupOfNames (RFC2307bis Schema). This group is member of a mailGroup (Postfix Schema). This mailGroup is member of another mailGroup. (Nested) membership in this last group defines access rights for an application.

My question: is the memberOf overlay able to recursively find all groups one is member of, if they use all the same "member" attribute (memberof.member-ad), but have different structural classes (memberof-group-oc)?

Is there a (perl?) script that is able to find all groups one is member-of?
