I am trying to bring up the anthentication module. Here are the list of what I have done.

1. Create MySQL tables and modify the permissions (SER could connect MySQL successfully)

2. Modify SER configuration (See below)

loadmodule "//usr/lib/ser/modules/mysql.so"

loadmodule "//usr/lib/ser/modules/auth.so"

modparam("usrloc", "db_url", "sql://ser:heslo@localhost/ser")
modparam("usrloc", "db_mode", 2)

modparam("auth", "db_url", "sql://ser:heslo@localhost/ser")
modparam("auth", "user_column", "user_id")
modparam("auth", "calculate_ha1", yes)
modparam("auth", "password_column", "password")

if (uri=~"sip\.abcd\.com") {
if (method=="REGISTER") {

# Uncomment this if you want to use digest authentication
                        if (!www_authorize("sip.abcd.com", "subscriber")) {
                                www_challenge("sip.abcd.com", "0");
                                break;
                        };

                        save("location");
                        break;
                };

After all these changes, SER could start without problem. But it seems that the Auth module doesn't take effect. For whatever username/password (whether it's included in the subscriber table or not), SER just allow the registration.

What maybe the problem? Is there anything wrong with the configuration?

Thanks.
