  It depends.

  If all of the passwords are in Active Directory, then you have to use ntlm_auth.

  You should be able to just check the machine credentials.  Try it with ntlm_auth.  It's a command-line tool that can be used on its own.

  You will need the correct password, and then store that in the "users" file.
