Wine has not been tested extensively in NT4 or AD domain environments, thank 
you for the feedback.

Ok, I wonder what security mode this is turning on in respect to SSPI.

I'm willing to believe it is a Wine issue, given that I wrote quite a bit of 
the Wine SSPI code. Just to make sure at what part of the chain this is 
failing, can you run your application with "WINEDEBUG=+secur32,+ntlm wine 
app.exe > wine_sspi_trace.txt 2>&1" and post the resulting log file? My first 
guess would be that the app tries to use SPNEGO or Kerberos when in an AD 
domain, and Wine does not handle that yet. It's on my todo list, and if 
that's what is stopping you from using your app, I can see if there is a way 
to fix it.
