Is safe mode activated? That might be your problem...

As of PHP 4.3.0, in order to prevent someone from writing a script which reveals the password for a page that was authenticated through a traditional external mechanism, the PHP_AUTH variables will not be set if external authentication is enabled for that particular page and safe mode is enabled. Regardless, REMOTE_USER can be used to identify the externally-authenticated user. So, you can use $_SERVER['REMOTE_USER'].
