When I delete, rename or change the location of a AD object (user, group, ...), then the referring entries aren't removed or updated in other group object(s) in AD. When I then open the properties of them I
recieve a SAM error (I had then to fix the entries in ADSI Edit manually). (Derived from bug 4815)
Since it's not really a bug, I'll mark it as a feature request.
How far are you with this?
With the linked attributes plugin, this should now be fixed!
