Get RackTables working with php-cgi or fastcgi

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']))
