Jeff, My point was that the uac_auth() is supposed to handle the realm matching for you. If you simply load all of the auth data based on the call target as you already plan to do, uac_auth() should look through that data for you to find credentials with a matching realm. You don’t need to do that part yourself in the script.

I think I've been looking at this too long. I checked the module and that's exactly what it is. My hope was to load the uac_auth user/pass AVPs ahead of time from a DB based on where I knew I was sending the call, load the realm one in the failure route based on what comes back in the header, and then fire the uac_auth() function. It looks like I may have to manually extract the realm from whichever header comes in. Not ideal, but probably workable. - Jeff On Thu, Sep 24, 2020 at 9:58 PM Ben Newlin <ben.new...@genesys.com<mailto:ben.new...@genesys.com>> wrote: This does not appear to be documented, but I believe uac_auth() looks through the AVPs configured in the UAC_AUTH module and uses the first one whose realm matches the challenge realm. So in order to authenticate any challenge, you must load all of the possible credentials into those AVPs.

Not from the ”Proxy-Authenticate” header, which is what you have. https://www.opensips.org/Documentation/Script-CoreVar-3-1#toc6<https://www.opensips.org/Documentation/Script-CoreVar-3-1#toc6> Ben Newlin From: Users <users-boun...@lists.opensips.org<mailto:users-boun...@lists.opensips.org>> Date: Thursday, September 24, 2020 at 9:31 PM To: OpenSIPS users mailling list <users@lists.opensips.org<mailto:users@lists.opensips.org>> Subject: [OpenSIPS-Users] learning the realm from authentication challenges I'm trying to recover the realm of an auth challenge to OpenSIPS so I can respond to it with the uac_auth() function, and that requires knowing the realm. The docs say that $ar<https://www.opensips.org/Documentation/Script-CoreVar-3-1#toc6> should provide that, perhaps written like $(<reply>ar) to get it in the right context. I'm having some trouble getting the data. failure_route[relay_failure] { ... if (t_check_status("407")) { xlog("L_NOTICE", "[1] Proxy-Authenticate: $(<reply>hdr(Proxy-Authenticate))\n"); xlog("L_NOTICE", "[2] Auth Realm: $(<reply>ar)\n"); xlog("L_NOTICE", "[3] Auth Realm: $ar\n"); } ... } The logs show: /usr/sbin/opensips[33044]: [1] Proxy-Authenticate: Digest realm="asterisk", nonce="5f6d42140000936ad820dbcd452e6bcd145777e458dd46dd", qop="auth" /usr/sbin/opensips[33044]: [2] Auth Realm reply: <null> /usr/sbin/opensips[33044]: [3] Auth Realm: <null> Is it possible to get the realm? Is it possible to build a response with uac_auth() for an arbitrary authentication challenge?
