[PHP] IIS and PHP authorization

[Shane McBride]

I finally got PHP, MySQL and Win2k installed after a long hard battle with a Promise 
Ultra/66 controller card. Now, PHP seems to work fine exceot when I have a script that 
requires authorization, I never get the popup box to input the login and password. 
Here's the script:

<?
  // Include the setup password file
  require 'setup.inc';
  
  // Check to see if $PHP_AUTH_USER already contains info
  if (!isset($PHP_AUTH_USER)) {
    // If empty, send header causing dialog box to appear
 header('WWW-Authenticate: Basic realm="The Merchant Power Setup Area"');
 header('HTTP/1.0 401 Unauthorized');
 echo 'Authorization Required!';
 exit;
  } else if (isset($PHP_AUTH_USER)) {
 if (($PHP_AUTH_USER !=$SETUP_USER) || ($PHP_AUTH_PW !=$SETUP_PASS)) {
   header('WWW-Authenticate: Basic realm="The Merchant Power Setup Area"');
   header('HTTP/1.0 401 Unauthorized');
   echo 'Authorization Required!';
   exit;
    }
 }
?>

Any ideas?
