[SR-Users] authentication is not working

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: # U 2011/02/03 09:31:04.402891 172.30.140.22:48752 -> 172.30.140.8:5060 REGISTER sip:172.30.140.8 SIP/2.0 Via: SIP/2.0/UDP 172.30.140.22:48752 ;branch=z9hG4bK-d87543-9a54af22967ae417-1--d87543-;rport Max-Forwards: 70 Contact: <sip:1000@172.30.140.22:48752;rinstance=fcade2df86ce0ab8> To: "1000"<sip:1000@172.30.140.8 &lt;sip%3A1000(a)172.30.140.8&gt;&gt; From: "1000"<sip:1000@172.30.140.8 &lt;sip%3A1000(a)172.30.140.8&gt;&gt;;tag=cd3e2323 Call-ID: MmU0YjM1NThiNTg0ZjhiNGM4ODA4ZmU1YWFiYjBmNTc.
