[ActiveDir] Domainless Login, can it be done?

[Rene Chakraborty]

Well we have a college in 45,000 users across 5 campuses.  What I have done is create a parent Domain where all of our servers site and then a child domain for each campus. Each child domain holds the user names and passwords for the students and staff of that campus.  Now for students who never goto the other campuses this has worked well.  The problem is when students say from campus A goto campus B for a class they can't login because the desktops at campus B are a member of the campus B domain and the students login is in campus A.  We generally try to make it as easy for our students to login as possible, so we would like to try and take the domain factor out of the login procedure.  Now I have been doing research and I was wondering if turning on "referral chasing" on the desktop would make that work?  Can it be done anyway to your knowledge? regardless of practicality.
