Yeah, I know - 3.2.x works fine. It's just 3.0.x that looks like it
doesn't like raw NTLMSSP. If I hack all of the the flags and such to
make the Type1Message look exactly like the SPNEGO-wrapped equivalent
Type1Message sent by smbclient, it still fails. So the only difference
looks like SPNEGO.

If you're not sure, then I'll recommend that the customer try to
upgrade to the latest 3.0 and see if that makes any difference.
