Description:
------------
So a dump of $_SERVER reveals that after a
<?

 header( 'WWW-Authenticate: Basic realm="WG Content-Management"' ); 

?>

that $_SERVER['PHP_AUTH_PW'] is set but not $_SERVER['PHP_AUTH_USER'] 

Any ideas?

Reproduce code:
---------------
if (isset( $_SERVER['PHP_AUTH_USER'] ) && isset($_SERVER['PHP_AUTH_PW'])) {
// code 

}

// always returns false regardless of what is entered


Expected result:
----------------
should return true if the "Authentication Box" is filled in
