I've installed Test Director on Windows 2000 Server and try to add users from Windows domain by means of Import (on the Users tab). According to the documentation I've added 2 parameters on the Site Config tab: Authentication and NTDomain. It has not helped me, anyway TD doesn't see Windows domain.
If I add a user mannually, windows authorization works perfectly. But it's not easy to add by hands. Do you have any ideas why TD doesn't see Windows domain?
