I do security administration for a large multi domain network. We have a master domain and multiple subordinate domains.
Recently we have been experiencing problems with users losing access to directories. Typically the users are members of global groups which are in local groups.
The local groups have permisson to access the directories but members of the global groups have suddenly lost access even though these global groups are members of the local groups.
If I add the users individuallythey regain access and if I give direct access to the global group they regain access.
The group structure I have inherited is a bit of a mess and to totally overhaul it would take more time than I have.
Does anyone have any idea why this problemhas suddenly started and why it is slowly spreading to other domains?
