[OpenSER-Users] Cannot authenticate SUBSCRIBE

[Eric PTAK]

Hi list !

I'm building an agent and currently working on Digest authentication using
auth and auth_db modules.
I'm trying to authenticate all requests for compliance test purpose.
It works fine with REGISTER but I can't authenticate for others methods like
SUBSCRIBE, the module is looping authentication.

This is a part of my config file :

        if (uri==myself) {
                if (!www_authorize("", "subscriber")) {
                        www_challenge("", "0");
                        exit;
                };
                // others things
        };

And this is the requests / responses :

As you can see, auth module always use
nonce="4811de4caf098eb6f25ea5db9a788578a2d4be35" in its responses, for both
register and subscribe.

thanks for your help,

Eric.
