Request headers bag is missing Authorization header in Symfony 2?

I'm trying to implement a custom authentication provider in Symfony 2. I'm sending a test request using Fiddler and printing all headers server side; well, Authorization header is missing.

Am i doing something wrong?

GET /RESTfulBackend/web/index.php HTTP/1.1
Authorization: FID 44CF9590006BF252F707:jZNOcbfWmD/
Host: localhost
User-Agent: Fiddler
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: it-it,it;q=0.8,en-us;q=0.5,en;q=0.3

Listener just prints the headers and quits:

class HMACListener implements ListenerInterface
{
    private $securityContext;

    private $authenticationManager;

    public function handle(GetResponseEvent $event)
    {
        $request = $event->getRequest();
        print_r($request->headers->all()); 
        die();
     }
}

Response is missing Authorization header:

Array
(
    [host] => Array
        (
            [0] => localhost
        )
    [user-agent] => Array
        (
            [0] => Fiddler
        )
    [accept] => Array
        (
            [0] => text/html,application/xhtml+xml,application/xml
        )
    [accept-language] => Array
        (
            [0] => it-it,it;q=0.8,en-us;q=0.5,en;q=0.3
        )
)

You must add this code to a virtualhost tag

It will not work if you put it in a Directory tag.

    RewriteEngine On
    RewriteCond %{HTTP:Authorization} ^(.*)
    RewriteRule .* - [e=HTTP_AUTHORIZATION:%1]

Akambi's answer didn't work for me, but found this answer in the php website:

"Workaround for missing Authorization header under CGI/FastCGI Apache:

SetEnvIf Authorization .+ HTTP_AUTHORIZATION=$0

Now PHP should automatically declare $_SERVER[PHP_AUTH_*] variables if the client sends the Authorization header."

Thanks derkontrollfreak+9hy5l!

The verified solution worked for me at the time to get the Authorization header through. However, it generated an empty Authorization header when there was none in the incoming request. This is how I solved it:

RewriteEngine On
RewriteCond %{HTTP:Authorization} .+
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

I had the same problem when writing a public API with custom Authorization header. To fix the HeaderBag I used a listener:

namespace My\Project\Frontend\EventListener;

use Symfony\Component\HttpFoundation\HeaderBag;

use Symfony\Component\HttpKernel\Event\GetResponseEvent;

/**
 * Listener for the REQUEST event. Patches the HeaderBag because the
 * "Authorization" header is not included in $_SERVER
 */
class AuthenticationHeaderListener
{
    /**
     * Handles REQUEST event
     *
     * @param GetResponseEvent $event the event
     */
    public function onKernelRequest(GetResponseEvent $event)
    {
        $this->fixAuthHeader($event->getRequest()->headers);
    }
    /**
     * PHP does not include HTTP_AUTHORIZATION in the $_SERVER array, so this header is missing.
     * We retrieve it from apache_request_headers()
     *
     * @param HeaderBag $headers
     */
    protected function fixAuthHeader(HeaderBag $headers)
    {
        if (!$headers->has('Authorization') && function_exists('apache_request_headers')) {
            $all = apache_request_headers();
            if (isset($all['Authorization'])) {
                $headers->set('Authorization', $all['Authorization']);
            }
        }
    }
}

and bound it to kernel.request in the service definition:

services:
  fix_authentication_header_listener:
    class: My\Project\Frontend\EventListener\AuthenticationHeaderListener
    tags:
      - { name: kernel.event_listener, event: kernel.request, method: onKernelRequest, priority: 255 }
