Unlike when calling uac_reg_request_to, you'll have to fill the
auth_*_avp pvs yourself. So in the example you have to fill $avp(auser)
and $avp(apass).

modparam("uac","auth_username_avp","$avp(auser)")
modparam("uac","auth_password_avp","$avp(apass)")
modparam("uac","auth_realm_avp","$avp(arealm)")

...

if(t_check_status("401|407")) {
	$avp(auser) = "test";
	$avp(apass) = "test";
	uac_auth();
	t_relay();
	exit;
}

So next problem is how to get those credentials. You already know the
user making the call. So either have a custom query to a custom table
(sqlops/avpops) to retrieve the external user/pass for current user, or
try to store that information with the subscriber data (saw some
suggestions for this a while back on the list).
