1495 Do you want session setups at user level security with a invalid
1496 password to be rejected or allowed in as guest? WinNT rejects them
1497 but it can be a pain as it means "net view" needs to use a password
1499 You have 3 choices in the setting of map_to_guest:
1501 "NEVER_MAP_TO_GUEST" means session setups with an invalid password
1502 are rejected. This is the default.
1504 "MAP_TO_GUEST_ON_BAD_USER" means session setups with an invalid password
1505 are rejected, unless the username does not exist, in which case it
1506 is treated as a guest login
1508 "MAP_TO_GUEST_ON_BAD_PASSWORD" means session setups with an invalid password
1509 are treated as a guest login
1511 Note that map_to_guest only has an effect in user or server
