1603    Do you want session setups at user level security with a invalid
1604    password to be rejected or allowed in as guest? WinNT rejects them
1605    but it can be a pain as it means "net view" needs to use a password
1606
1607    You have 3 choices in the setting of map_to_guest:
1608
1609    "NEVER_MAP_TO_GUEST" means session setups with an invalid password
1610    are rejected. This is the default.
1611
1612    "MAP_TO_GUEST_ON_BAD_USER" means session setups with an invalid password
1613    are rejected, unless the username does not exist, in which case it
1614    is treated as a guest login
1615
1616    "MAP_TO_GUEST_ON_BAD_PASSWORD" means session setups with an invalid password
1617    are treated as a guest login
1618
1619    Note that map_to_guest only has an effect in user or server
1620    level security.
