Hello Naresh.
    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.

Good luck

Hi Ricardo,

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

Thanks a lot..

Hello Naresh
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?

Cheers,
Ricardo.-

Asunto: [Serusers] Problem authorizing with radius

hi friends,

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.
Delaying request 2 for 1 seconds
Finished request 2

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

Best Regards,
Naresh
