1624 password to be rejected or allowed in as guest? WinNT rejects them
1625 but it can be a pain as it means "net view" needs to use a password
1627 You have 3 choices in the setting of map_to_guest:
1629 "NEVER_MAP_TO_GUEST" means session setups with an invalid password
1630 are rejected. This is the default.
1632 "MAP_TO_GUEST_ON_BAD_USER" means session setups with an invalid password
1633 are rejected, unless the username does not exist, in which case it
1634 is treated as a guest login
1636 "MAP_TO_GUEST_ON_BAD_PASSWORD" means session setups with an invalid password
1637 are treated as a guest login
