[Serusers] How to check the username if it is registered or not

[Tung Tran]

Hi all,

I am trying to do radius_proxy_authenticate for INVITE message, but I got new trouble:
- Radius server reply with Access-Accept.
- But SER always understands the authentication is false and do proxy_challeng all the time (althrough all the debug I see  on the debug   >>radius_authorize_sterman(): Success..)

Please tell me what I am wrong ( I am using SER 0.8). 

Thanks in advance, Tung

Here is my conf for radius_proxy_authenticate.
				if (method == "INVITE" && (uri=~"^sip:00"))		
          		{

 			 				if (!radius_proxy_authorize(""))
							 {
					     		xlog("L_INFO", "Radius proxy authorized false, Challenging .. \n");
					     		proxy_challenge("", "0"); 
					     		break; 
							 };

							 xlog("L_INFO", "Radius proxy authorized OK, process call routing .. \n");
							 consume_credentials();						 		
							 
							 log (1, "************* PC2Phone Using AsteriskB2UBA, Rewriting the host:port **************");
							 rewritehostport ("x.x.x.x:5071");
							 use_media_proxy();
              						 t_on_reply("1");
							.............

			}

And here is the debug on SER
