I have many, many users that cannot change members of their distribution groups through the GAL.
The check box for "Manager can update membership list" is checked in Active Directory.
The security permissions also show that the user has "write members" selected as a property and no denies.
If given access to the Active Directory Users and Computers MMC, the user (logged in as them) can change the membership list. It only appears that it will not work when the users try changing them in the GAL.
Any ideas at all?
I personally would do this with RBAC and create a custom role group. I would recommend placing your distribution groups in certain OU's and set your scope to OU. The one thing I love about RBAC is that it can get as granular as you would like to.
