i have such a function in my radius_auth module.  i call it after lookup
fails in order to find out if the request uri belongs to an existing
user.

        if (!lookup("location")) {
            if (radius_does_uri_exist()) {
                sl_send_reply("480", "Temporarily Unavailable");
                break;
            };
            sl_send_reply("404", "Not Found");
            break;
        };

i don't know if that function will be part of the coming, new official
radius_auth module.
