1589 password to be rejected or allowed in as guest? WinNT rejects them
1590 but it can be a pain as it means "net view" needs to use a password
1592 You have 3 choices in the setting of map_to_guest:
1594 "NEVER_MAP_TO_GUEST" means session setups with an invalid password
1595 are rejected. This is the default.
1597 "MAP_TO_GUEST_ON_BAD_USER" means session setups with an invalid password
1598 are rejected, unless the username does not exist, in which case it
1599 is treated as a guest login
1601 "MAP_TO_GUEST_ON_BAD_PASSWORD" means session setups with an invalid password
1602 are treated as a guest login
