I reproduced this problem on Linux box. I see packet captures and confirm
that Samba replies to enable plaintext password, Windows client sends a
plaintext password, and at last Samba replies logon failure to client.

My smb.conf is:

  encrypt passwords = no
  server max protocol = nt1
  ntlm auth = yes

  path = /tmp
  writeable = yes

Hmmm, I think it is a bug...
