As I said before... Not as far as I know. A quick look in the code (modules/aaa/mod_auth_basic.c) shows that mod_auth returns the same value (HTTP_UNAUTHORIZED) if there's no auth header OR wrong scheme OR password mismatch OR user not found

So you can't tell what caused the request to fail which means that no credentials (first request) = bad request.

The thing is that Basic Auth is, as the name implies, "basic". If you want to do clever stuff like you do, you really have to go for a cookie-driven login scheme that has more server-sided intelligence. Since you're already using PHP, there are lots of PHP-based closed user group solutions - search on www.php.net.
