Hi Eric,

You should try to use proxy_auth() and proxy_challenge() for the SUBSCRIBE....

Regards,
Bogdan

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.
