  Hello,

 Thanks a lot for your advice, I found and solved the problem thanks to 
 the debugger, actually the problem was with

 modparam("auth_db", 
 "db_url","mysql://openser:openserrw@localhost/openser")

 I just had to change localhost to my locationserver IP and the problem 
 was solved :), thanks again. 
good that you find it. Don't forget to cc the mailing list always so 
people reading the thread (archive later) see the conclusion -- it can 
help many others running on same situation.

Cheers,
Daniel

     Hello,

     you have another group of actions that can send 401 Unauthorized:

                    if (!check_to()) {
                            sl_send_reply("401", "Unauthorized");
                            exit;
                    }

     You can either run with debug=4 and watch the syslog to see some
     hints in messages where it fires this 401, or use debugger module
     with cfgtrace option set and you see the execution path of the
     config in the logs.

     If you send here the ngrep of such REGISTER and the reply we can
     spot what could be the situation for 401.

     Cheers,
     Daniel

      Hello sr-users,

     I'm new using kamailio open source, and I would like to ask for help.

     My version is 3.1.4 and I am trying to configure 3 servers, one
     with proxy, one with registrar and one with location server.

     My problem is when I try to send a register message it returns an
     error "401 Unauthorized", I know the error is in the fuction
     www_authorize("10.254.239.7", "subscriber") but I don't know
how
     to solve it, for me it seems correct the parameters.

     Below I have attatched the proxy and registrar relevant route
     code for my problem, and the IPs for proxy an registrar are:
     10.254.239.7-----------10.254.239.8

     If someone can help me, I will be gratefull. Thanks in advance.

     ####REGISTRAR CODE

     route{

            # initial sanity checks -- too long messages
            if (msg:len >=  2048 ) {
                    sl_send_reply("513", "Message too big");
                    exit;
            };

            if (!uri==myself) {
                    sl_send_reply("400", "Bad destination, only
     register messages de$
                    exit;
            };

            # the only valid message for the registrar is the register
     message
            # other messages are answered with an error message
            if (uri==myself) {

                    if (method=="REGISTER") {

                            sl_send_reply("100", "Trying");

                    if (!www_authorize("10.254.239.7", "subscriber"))
{
                            www_challenge("10.254.239.7", "1");
                            exit;
                    };

                    if (!check_to()) {
                            sl_send_reply("401", "Unauthorized");
                            exit;
                    };

                     consume_credentials();
                            if(!save("location")) {
                                    sl_reply_error();
                            };
                            exit;
                    } else {
                            sl_send_reply("403", "Forbidden");
                            exit;
                    };
            };
     }

     #########PROXY CODE

                    if (method=="ACK") {
                     route(1);
                     exit;
                     } if (method=="INVITE") {
                     route(3);
                     exit;
                     } else if (method=="REGISTER") {
                     route(2);
                     exit;
                      };

                    lookup("aliases");
                    if (!uri==myself) {
                            route(1);
                    };

     route[2] {
            #rewrinting the host allows the registrar to know that the
     message is de$

            rewritehost("10.254.239.8");
            if(!t_relay()) {
                    sl_reply_error();
            };
            exit;
     }
