1545 Do you want session setups at user level security with a invalid
1546 password to be rejected or allowed in as guest? WinNT rejects them
1547 but it can be a pain as it means "net view" needs to use a password
1549 You have 3 choices in the setting of map_to_guest:
1551 "NEVER_MAP_TO_GUEST" means session setups with an invalid password
1552 are rejected. This is the default.
1554 "MAP_TO_GUEST_ON_BAD_USER" means session setups with an invalid password
1555 are rejected, unless the username does not exist, in which case it
1556 is treated as a guest login
1558 "MAP_TO_GUEST_ON_BAD_PASSWORD" means session setups with an invalid password
1559 are treated as a guest login
1561 Note that map_to_guest only has an effect in user or server
