Member of nested groups of different classes

["Chris" <chris2014@postbox.xyz>]

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?
