Add/Remove self as a member permission.

Hello There...

I have a globle group name "My Enterprise Admin" who is a member of
Domain Admin in AD.


I created another group name "Admin Manger Enterprise".


I added Admin Manage Entrprise in a security tab of "My Enterprise
Admin" Group and assigb Add/Remove self as a member permission.


After an hour this group is removed from the permission.


And I found following in event log:
