1232    Do you want session setups at user level security with a invalid
1233    password to be rejected or allowed in as guest? WinNT rejects them
1234    but it can be a pain as it means "net view" needs to use a password
1235
1236    You have 3 choices in the setting of map_to_guest:
1237
1238    "NEVER_MAP_TO_GUEST" means session setups with an invalid password
1239    are rejected. This is the default.
1240
1241    "MAP_TO_GUEST_ON_BAD_USER" means session setups with an invalid password
1242    are rejected, unless the username does not exist, in which case it
1243    is treated as a guest login
1244
1245    "MAP_TO_GUEST_ON_BAD_PASSWORD" means session setups with an invalid password
1246    are treated as a guest login
1247
1248    Note that map_to_guest only has an effect in user or server
1249    level security.
