972 Do you want session setups at user level security with a invalid
973 password to be rejected or allowed in as guest? WinNT rejects them
974 but it can be a pain as it means "net view" needs to use a password
976 You have 3 choices in the setting of map_to_guest:
978 "NEVER_MAP_TO_GUEST" means session setups with an invalid password
979 are rejected. This is the default.
981 "MAP_TO_GUEST_ON_BAD_USER" means session setups with an invalid password
982 are rejected, unless the username does not exist, in which case it
983 is treated as a guest login
985 "MAP_TO_GUEST_ON_BAD_PASSWORD" means session setups with an invalid password
986 are treated as a guest login
988 Note that map_to_guest only has an effect in user or server
