secur32: Work around ntlm_auth in Samba 3.0.28a being broken for cached credentials.

Samba 3.0.28a (as shipped with Ubuntu 8.04) seems to break when using
cached credentials backed by winbindd, returning a BH error in our test
if we still need to provide a password. Handle this and report a more
correct error.
