I've been trying out the Active Directory authentication. In my company we have more than one domain, but they all are trusted. What I am finding that is I have a SQL Monitor server in domain A, then I can't have users from domain B access the server with Windows authentication. I have added users with domain B to a group in domain A, and the group in domain A is added in SQL Monitor with a select list of servers. Any users in domain A that are in the group can access the SQL Monitor web site. Users in domain B cannot. Am I missing anything on how to set it up?
