s3:ntlmssp Don't use the lm key if the user didn't supply one.
This may help to avoid a number of possible MITM attacks where LM_KEY is
spoofed into the session. If the login wasn't with lanman
(and so the user chose to disclose their lanman response),
don't disclose back anything based on their lanman password.
