[Serusers] Ser.cfg authentication problems

Hi all I have some problems to configure ser to authenticate through radius. I compiled modules for auth_radius . i checked the freeradius with radtest and it's working fine, the problem is that ser is not talking to freeradius. inside ser.cfg ------------------------------------------------- loadmodule "/usr/local/lib/ser/modules/auth.so" loadmodule "/usr/local/lib/ser/modules/auth_radius.so" modparam("auth_radius", "radius_config","/usr/local/etc/radiusclient/radiusclient.conf") modparam("auth_radius", "service_type", 15) if (method=="REGISTER") { log(1, "REGISTER: Authenticating user\n"); if (!radius_www_authorize("")) { log(1, "REGISTER: challenging user\n"); www_challenge("", "0"); break; }; save("location"); sl_send_reply("200","ok"); break; }; I don't see anything happens inside radius when it's coming to authentication. now inside /var/logs/messages i see : ser[11562]: REGISTER: Authenticating user ser[11562]: REGISTER: challenging user it means what the request is going inside this "IF" but nothing happens, it looks like ser not talking to the radius. what it can be any suggestions. Thanks you guys for any help. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
