If the location is also saved in kamailio, then it is save(...) that generates the 200ok, independent of authentication mechanism. So all works fine without need to fetch user/password to use them in kamailio.cfg. For auth in external app - you can get the auth attributes from the Proxy-/Authorization header. You can send all that header to the external application -- for example, for REGISTER the var $hdr(Authorization) will give you those attributes.
