[Resolvido] Problema com Zend_Auth

Oi,

Estou tendo um problema um tanto surreal!

AuthenticationController.php

<?php
class Admin_AuthenticationController extends Zend_Controller_Action
{

private $_moduleName = null;
private $_controllerName = null;
private $_actionName = null;

 public function init()
 {
 // set params
 $this->_moduleName = $this->_request->getModuleName();
 $this->_controllerName = $this->_request->getControllerName();
 $this->_actionName = $this->_request->getActionName();

 // setLayout('login') caso seja chamado a action login
 if ( $this->_controllerName == "authentication" && $this->_actionName == "login" ) {
 // Zend_Auth
 $auth = Zend_Auth::getInstance();
 if ( $auth->hasIdentity() ){
 $this->_redirect( '/admin/index/index' );
 }else {
 // set layout to login
 $this->_helper->layout->setLayout( 'login' );
 }
	}
 }

 public function indexAction()
 {
 $this->_redirect( 'login' );
 }

 public function loginAction()
 {
 $formLogin = new AdminForm_Login();

 if ( $this->getRequest()->isPost() ) {
 if ( $formLogin->isValid( $this->_request->getPost() ) ) {
 $authAdapter = $this->_getAuthAdapter();

 $username = $formLogin->getValue( 'username' );
 $password = $formLogin->getValue( 'password' );

 $authAdapter->setIdentity( $username )
 ->setCredential( $password );

 $auth = Zend_Auth::getInstance();
 $result = $auth->authenticate( $authAdapter );

 if ( $result->isValid() ) {
 $identity = $authAdapter->getResultRowObject();
 $authStorage = $auth->getStorage();
 $authStorage->write( $identity );

 $this->_redirect( '/admin/index/index');
 }else {
 $this->view->errorMessage = "Login inválido!";
 }
 }
 }

 $this->view->form = $formLogin;

 }

 public function logoutAction()
 {
 $authAdapter = Zend_Auth::getInstance();
 $authAdapter->clearIdentity();

 $this->_redirect( '/admin/index/index' );
 }

 private function _getAuthAdapter()
 {
 $authAdapter = new Zend_Auth_Adapter_DbTable( Zend_Db_Table::getDefaultAdapter() );
 $authAdapter->setTableName( 'cms_users' )
 ->setIdentityColumn( 'email' )
 ->setCredentialColumn( 'password' )
 ->setCredentialTreatment( 'md5(?) AND active = 1' );

 return $authAdapter;
 }

}

No IE9 (versão que tenho instalada, não sei se faz o mesmo em todos!) quando noutro controller faço o seguinte:

$auth = Zend_Auth::getInstance();
$identity = $auth->getStorage()->read();

var_dump( $identity); // Restorna-me sempre NULL

Só que isto só me está a acontecer neste projecto e no IE! :angry:

Alguém já passou pelo mesmo, ou sabe o porquÊ?
