Bogdan,
The password is provided in plaintext by the db. The working scenario looks
likes this :
loadmodule "auth.so"
loadmodule "auth_db.so"
modparam("auth_db", "calculate_ha1", yes)
modparam("auth_db", "password_column", "password")
#modparam("auth_db", "db_url",
modparam("auth_db", "db_url",
"http://myauthdb")
modparam("auth_db", "load_credentials", "")
