[Users] Openser not consuming the credentials

I have openser set up to remove previously authorized credentials from the message being processed by the server, using consume_credentials. Yet the authorization credentials are still being passed. Any help is as always appreciated. Thank you. The related openser.cfg portions are posted below... if (!www_authorize("", "subscriber")) { www_challenge("", "1"); break; }; consume_credentials(); save("location"); break; if I then restart openser, make a call and start tethereal I get.... tethereal -V port 5060 | grep username Authorization: Digest username="theusernamewashere",realm="ser1.manhattan.whatever.net",nonce= "43457703fa69c4dd5321a7229ea41102f2200390",uri="sip: 13143212222(a)ser1.manhattan.whatever.net",algorithm=MD5,response="fc57c2b 4897d3d7b8ad887a788bf07f6",qop=aut
