Symfony functional test - can't stay logged in
===

After successfully using the crawler to log in I can't seem to stay authenticated. Once i'm authenticated I want to be able to run through each of my services and check the receive the correct response.

    public function testGetClientsAction()
    {
        $client = static::createClient();
        $client->followRedirects();

        $cookie = new Cookie('locale2', 'en', time() + 3600 * 24 * 7, '/', null, false, false);
		$client->getCookieJar()->set($cookie);
	
        // Visit user login page and login
	    $crawler = $client->request('GET', '/login');
	    $form = $crawler->selectButton('login')->form();
	    $crawler = $client->submit($form, array('_username' => 'greg', '_password' => 'greg'));
	    $client->insulate();

		$client->request(
	       'GET', 
	       '/clients/12345', 
	        array(), 
	        array(), 
	        array('X-Requested-With' => "XMLHttpRequest")
        );

        print_r($client->getResponse()->getContent());
        die();

    }

The print_r returns the page redirected to after login.
