1231    Do you want session setups at user level security with a invalid
1232    password to be rejected or allowed in as guest? WinNT rejects them
1233    but it can be a pain as it means "net view" needs to use a password
1234
1235    You have 3 choices in the setting of map_to_guest:
1236
1237    "NEVER_MAP_TO_GUEST" means session setups with an invalid password
1238    are rejected. This is the default.
1239
1240    "MAP_TO_GUEST_ON_BAD_USER" means session setups with an invalid password
1241    are rejected, unless the username does not exist, in which case it
1242    is treated as a guest login
1243
1244    "MAP_TO_GUEST_ON_BAD_PASSWORD" means session setups with an invalid password
1245    are treated as a guest login
1246
1247    Note that map_to_guest only has an effect in user or server
1248    level security.
