It seems I have an odd problem as the GAL is showing all users from at least 2 of my domains. I have now added a new domain with about 20 users and the same thing is happening.(after forcing a sync) I have seen some Forum posts but it seems the fixes are for people wanting this behavior with some responses saying this is not possible. I must have some configuration issue with in my system.
I dont want any domains to show GAL results for any other domains. Any way I can troubleshoot where the problem might be since I never (to my knowledge) made any configuration changes to the GAL before.
