I have a Win2k domain with a Mac using SMB. We are trying to use Windows
Integrated Authentication to access custom app via IIS. Before moving to
domain model, the user had no trouble logging in to the app using a local
Windows user group upon prompt. Now, when logging in via the domain user
account, it seems to load only a few lines of code, then won't go anymore.
Very strange...no error messages.
