  You haven't told the server what the "known good" password is.
Configure that, and it will work.

  It also looks like it's doing host authentication.  In that case, the
only entity that knows the password is Active Directory.  You will need
to set up Samba && ntlm_auth in order to authenticate these machines.

  See my site for more details:
