Hello my friends, 
 
I'm trying to configure authentication on my Kamailio and is not working at all :(
 
I've added the following to the script to make it work: (but it doesn't)
 
...
loadmodule "auth.so"
loadmodule "auth_db.so"
...
modparam("usrloc", "db_url",
                        "mysql://kamailio:kamailiorw@localhost/kamailio")
modparam("auth_db", "calculate_ha1", yes)
modparam("auth_db", "password_column", "password")
modparam("auth_db", "db_url",
                        "mysql://kamailio:kamailiorw@localhost/kamailio")
modparam("auth_db", "load_credentials", "")
...
        if (!(method=="REGISTER") && from_uri==myself) /*no multidomain version*/
        {
                if (!proxy_authorize("", "subscriber")) {
                        proxy_challenge("", "0");
                        exit;
                }
                if (!db_check_from()) {
                        sl_send_reply("403","Forbidden auth ID");
                        exit;
                }
                consume_credentials();
        }
...

        if (is_method("REGISTER"))
        {
                # authenticate the REGISTER requests (uncomment to enable auth)
                if (!www_authorize("", "subscriber"))
                {
                        www_challenge("", "0");
                        exit;
                }
                ##
                if (!db_check_to())
                {
                        sl_send_reply("403","Forbidden auth ID");
                        exit;
                }
                if (!save("location"))
                        sl_reply_error();
                exit;
        }

 
But is not working at all...take a look:
