You have 3 choices in the setting of map_to_guest:
1814
"NEVER_MAP_TO_GUEST" means session setups with an invalid password
1815
are rejected. This is the default.
1817
"MAP_TO_GUEST_ON_BAD_USER" means session setups with an invalid password
1818
are rejected, unless the username does not exist, in which case it
1819
is treated as a guest login
1821
"MAP_TO_GUEST_ON_BAD_PASSWORD" means session setups with an invalid password
1822
are treated as a guest login
1824
Note that map_to_guest only has an effect in user or server
