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

   "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

   "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.
