Users are not registering on my Kamailio - sr-users

HEllo community,

I'm having some problems with my kamailio configuration, following is the
section of my authentication process on my /etc/kamailio/kamailio.cfg

route [3] {
          if (is_method("REGISTER")) {
                  if (!www_authorize("", "subscriber")) {
                       www_challenge("", "0");
                       exit;
                  }

                     if ($au!=$tU) {
                        sl_send_reply("403", "Forbidden auth ID");
                            exit;
                  }
               } else {
                        if (from_uri==myself) {
                            if(!proxy_authorize("", "subscriber")) {
                                         proxy_challenge("", "0");
                                         exit;
                        }

                         if (is_method("PUBLISH"))  {
                                 if ($au!=$tU) {
                                      sl_send_reply("403", "Forbidden auth
ID");
                                      exit;
                              }
                           } else {
                             if ($au!=$fU) {
                               sl_send_reply("403", "Forbidden auth
ID");
                               exit;
                          }
                     }
                     consume_credentials();
           }
         }
         return;
}

I added a user with the following command:

# kamctl add 1102 123456

And then i checked on mysql, table subscriber:

mysql> select * from subscriber;
+----+----------+---------------+----------+---------------+----------------------------------+----------------------------------+------+
| id | username | domain        | password | email_address | ha1
                 | ha1b                             | rpid |
+----+----------+---------------+----------+---------------+----------------------------------+----------------------------------+------+
|  3 | 1102     | dannydias.com |          |               |
fe7a80817383cfd90950dea03d37eccf | dbb9b6ef93d4f3417038a6bf5cd176db | NULL
|
+----+----------+---------------+----------+---------------+----------------------------------+----------------------------------+------+
1 row in set (0.00 sec)

By the way, the domain field does not exist (dannydias.com) i'm not sure how
this could affect the authentication process, this migh be the problem?

And finally, ngrep-sip to check what is going on:
