I can reproduce this here. Looks like ntlm_auth fails because it's not supplied with a password and it can't retrieve any cached credentials.
Yep, exactly the same symptoms here.
I wonder if such a call sequence would succeed on Windows because the user has already logged on to the OS?
I don't see anything wrong with the call sequence, the app does AcquireCredentialsHandleW() followed by InitializeSecurityContextW(). That's a normal sequence to start with.
