Sorry if the answer to my question is already in the forum, I searched but was not able to find a answer. My problem: I process a list of users and want to find out whether or not a user is member of a specific group. This is not a big problem at first sight, I just process all groups the user is member of to find the matching one... But if the group to test is a nested one (i.e. let's say we have groups named Users-A and Users-B and a Group All-Users and Users-A and Users-B are member of All-Users, my fist aproach fails \:\(

Thanks for hint!
