Cookies, session, subdomain

I have test.local and subdomain.test.local both configured to work with one yii appliacation

I use demo blog Authentication (http://www.yiiframework.com/doc/blog/1.1/en/prototype.auth)

After authentication on test.local/?r=site/login and redirecting to test.local/?r=site/index


	public function actionIndex()

	{

		echo Yii::app()->user->id;


	}

I get the value of Yii::app()->user->id;

But if i go to subdomain.test.local?r=site/login

I can’t get the value of it.

After a lot of googling i put this to config


        'session' => array(    

            'cookieParams' => array('domain' => '.test.local'),

        ),    

		'user'=>array(

			'allowAutoLogin'=>true,

            'identityCookie' => array('domain' => '.test.local'),

		),

But it doesn’t help me too :(

So i can’t access session data from subdomain if it was started on domain.

And i can’t get session data in subdomain even if it was started in subdomain(test.local/?r=site/login).
