We have a SQL 2000 server which is in an Active Directory domain; I have users which are required to access the SQL server from outside AD using domain authentication.

The Active Directory team in their wisdom won’t allow AD to trust any other domain.

Are there any SQL hacks which will allow SQL within AD to trust other domains?

You could just use SQL security and be done with the problem... I am not an expert on AD but I believe it can trust other domains if you set it up correctly.

Hmm, yes the best solution would be to use SQL authentication however the software uses domain auth. I believe the AD team wont allow trusts becuase of security.

I am not an expert at AD but I believe you can setup trusted connections between domains and that would fix your problem right? I try to always use SQL security on database apps because I don't want to have to add some users in my AD domain.
