使用CakePHP的SimpleSAML-SimpleSAML_Error_NoState：NOSTATE

Question

I'm trying to configure SimpleSAMLPHP using CakePHP, in the project using just PHP it works fine but using CakePHP-simpleSAMLphp-Plugin I received the errors when I try to access the view :

    Warning (4096): Argument 1 passed to SamlAuthenticate::unauthenticated() must be an instance of Controller, instance of CakeRequest given, called in C:\Users\Alessandro\workspace\RW1\Projetos\Intranet\lib\Cake\Controller\Component\AuthComponent.php on line 348 and defined [APP\Plugin\Saml\Controller\Component\Auth\SamlAuthenticate.php, line 49]

Redirect   
You were redirected to: https://mysaml:9443/samlsso?...

And after the login I received the return :

SimpleSAML_Error_NoState: NOSTATE
Backtrace:
2 C:\xampp\simplesaml\lib\SimpleSAML\Auth\State.php:225 (SimpleSAML_Auth_State::loadState)
1 C:\xampp\simplesaml\modules\saml\www\sp\saml2-acs.php:63 (require)
0 C:\xampp\simplesaml\www\module.php:134 (N/A)

I'm using CakePHP (2.5.2) and SimpleSAMLPHP (1.13.2)

EDIT

This is the method unauthenticated():

public function unauthenticated(Controller $controller) {
        return $this->Saml->isAuthenticated();
    }

This is var_dump of $controller :

      ["value"]=>

    }
  }
  ["_input":protected]=>
  string(0) ""
}

And I tryied change to :

public function unauthenticated(CakeRequest $controller) {
        $controller = $controller->params['controller'];
        return $this->Saml->isAuthenticated();
    }

The warning not happens but still not work.

Link of the resolution: https://github.com/zl4bv/CakePHP-simpleSAMLphp-Plugin/issues/7#issuecomment-63427478

I needed to change the type of session to 'sql' in config/config.php :

'store.type' => 'sql',

And all works fine!
