If you’ve tried to google “racktables authentication not working after install” you won’t find much, but there is a couple of articles about fastcgi and the PHP_AUTH_PW and PHP_AUTH_USER not being passed correctly. But no real solution to the problem.

I was able to get RackTables working using the following work around posted on http://www.rosmir.org/Index/Docs/archive/LabsFolder/FastCGI which has nothing to do with RackTables.

  1. You will need to add the following to your .htaccess file.
    RewriteEngine on
    RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]
  2. Next you will need to modify the inc/auth.php file and add the following before the function authenticate.
    if(preg_match('/Basic+(.*)$/i', $_SERVER['REDIRECT_HTTP_AUTHORIZATION'], $matches)) {
    list($_SERVER['PHP_AUTH_USER'], $_SERVER['PHP_AUTH_PW']) = explode(':' , base64_decode(substr($_SERVER['REDIRECT_HTTP_AUTHORIZATION'], 6)));
    }
  3. It should look like following below when completed.
    function authenticate ()
    {
    if(preg_match('/Basic+(.*)$/i', $_SERVER['REDIRECT_HTTP_AUTHORIZATION'], $matches)) {
    list($_SERVER['PHP_AUTH_USER'], $_SERVER['PHP_AUTH_PW']) = explode(':' , base64_decode(substr($_SERVER['REDIRECT_HTTP_AUTHORIZATION'], 6)));
    }
    global
    $remote_username,
    $remote_displayname,
    $auto_tags,
    $user_given_tags,
    $user_auth_src,
    $script_mode,
    $require_local_account;
    if (!isset ($user_auth_src) or !isset ($require_local_account))
    throw new RackTablesError ('secret.php: either user_auth_src or require_local_account are missing', RackTablesError::MISCONFIGURED);
    if (isset ($_REQUEST['logout']))
