Mmmhh, are you sure you modified the de www_challenge for the proxy_challenge in the ser.cfg file?. I use RADIATOR as my Radius Server so i'm not very familiarized with freeRadius. But for the debug it seems to be an error maybe with the configuration from the Radius Server?

For example , is normal this : Invalid operator for item Suffix: reverting to '==' ?

Maybe somone that uses freeRadius could give you more details.

To accounting i use Radiator but working together with an Oracle Database, i use the Start and Stop message from SER to bill the call.

Tried it. It still gives me the same error. Please let me know the version of the radius server you are using.?? Also can you please let me know wht did u do to make the accounting work...??

I guess there is an error in the way you call the authorization for the INVITE. As far as i know for the REGISTER message (authentication) you need the statement :

radius_www_authorize

But for the INVITE you need to call "radius_proxy_authorize". This is what i have in my ser.cfg

if (method=="INVITE") {

                if (!radius_proxy_authorize("")) {
                        proxy_challenge("","1");
                        break;
                };
        };

maybe you can try this and tell me how it works.

We are using freeradius server 0.9.1 and SER 0.9.3. The version of radius client is radiusclient-ng-0.5.1. The users file in the radius server looks like as below:

test@sip2.zone Auth-Type := Digest, User-Password == "cisco1234"
Reply-Message = "Authenticated",
Sip-Rpid = "1970"

test@sip2.zone Auth-Type := Accept
Reply-Message = "Authorized",
Sip-Group == "ld"

The radius authentication and authorization parts in the ser.cfg file are given below:

if (uri=~"^sip:9[0-9]*@") {
                        if (method=="INVITE"){
                                if (!radius_www_authorize("")) {
                                         www_challenge("", "1");
                                        break;
                                }else{
                                        if (radius_is_user_in("Credentials", "ld")){
                                                forward(192.168.2.101,5060);
                                                break;
                                        }else{
                                                break;
                                        };
                                };
                        };
                };

As you can see from the above configuration, the authentication works perfect, its only in the authorization where it fails. Also can you please let me know about the accounting configuration??

I have authentication, authorization and accounting (AAA) through radius working fine. What radius server are you using?, can you send us more information about the configuration?

I am having problems while authorizing with the radius server. I am using the same configuration as mentioned in the radius-howto. Authentication works perfect as I am able to authenticate using the radius server. However while authorizing against the radius server to make a call I get the following error:

auth: No authenticate method (Auth-Type) configuration found for the user
request: Rejecting the user
auth: Failed to validate the user.

When I authorize against the mysql database, it works fine. Any clue???
