Do you want session setups at user level security with a invalid
1729
password to be rejected or allowed in as guest? WinNT rejects them
1730
but it can be a pain as it means "net view" needs to use a password
1732
You have 3 choices in the setting of map_to_guest:
1734
"NEVER_MAP_TO_GUEST" means session setups with an invalid password
1735
are rejected. This is the default.
1737
"MAP_TO_GUEST_ON_BAD_USER" means session setups with an invalid password
1738
are rejected, unless the username does not exist, in which case it
1739
is treated as a guest login
1741
