 This is a network logon packet. The log_id parameters
 are what an NT server would generate for LUID once the
 user is logged on. I don't think we care about them.

 Note that this has no access to the NT and LM hashed passwords,
 so it forwards the challenge, and the NT and LM responses (24
 bytes each) over the secure channel to the Domain controller
 for it to say yea or nay. This is the preferred method of
 checking for a logon as it doesn't export the password
 hashes to anyone who has compromised the secure channel. JRA.
