I've seen a few requests related to domain authentication here so it looks like there is a need for enhancements in this area. My use-case is a bit different still.
We have DomainA which VC is tied to for authentication in our data center. DomainB is in our office and is where I want to run the VC client with domain auth but can't.
If my username/password are the same for DomainA & DomainB I would like the authentication to work. This setup works for Windows Explorer, through IE, SQL Studio Management tools and various other applications I use that support AD auth.
VC is one of the only ones that does not.
