1676    "NEVER_MAP_TO_GUEST" means session setups with an invalid password

1678
1679    "MAP_TO_GUEST_ON_BAD_USER" means session setups with an invalid password
1680    are rejected, unless the username does not exist, in which case it
1681    is treated as a guest login
1682
1683    "MAP_TO_GUEST_ON_BAD_PASSWORD" means session setups with an invalid password
1684    are treated as a guest login
