I have been trying with AD to traverse a tree... such as: A - Company distribution list \ B - Business Operations distribution list / \ C D - IT Operations distribution list \ E - Visual Studio's distribution list If I am in distribution list E and B is granted some sort of rights within my application ( To view a certain document or module ), how can I, using LDAP_search, traverse that tree and realize that E is a member of B and therefore I should be given the rights as well. Not only is E a member, but so is C and D and they should have the same grants as well. dean.ericson@xxxxxxxx
