1599    You have 3 choices in the setting of map_to_guest:
1600
1601    "NEVER_MAP_TO_GUEST" means session setups with an invalid password
1602    are rejected. This is the default.
1603
1604    "MAP_TO_GUEST_ON_BAD_USER" means session setups with an invalid password
1605    are rejected, unless the username does not exist, in which case it
1606    is treated as a guest login
1607
1608    "MAP_TO_GUEST_ON_BAD_PASSWORD" means session setups with an invalid password
1609    are treated as a guest login
1610
1611    Note that map_to_guest only has an effect in user or server
1612    level security.
