   Do you want session setups at user level security with a invalid

   but it can be a pain as it means "net view" needs to use a password

   You have 3 choices in the setting of map_to_guest:

   "NEVER_MAP_TO_GUEST" means session setups with an invalid password
   are rejected. This is the default.

   "MAP_TO_GUEST_ON_BAD_USER" means session setups with an invalid password
   are rejected, unless the username does not exist, in which case it
   is treated as a guest login

   "MAP_TO_GUEST_ON_BAD_PASSWORD" means session setups with an invalid password
   are treated as a guest login

   Note that map_to_guest only has an effect in user or server
   level security.
