        if (isset($serviceName)) {
            /** @var $eauth EAuthServiceBase */
            $eauth = Yii::app()->eauth->getIdentity($serviceName);
            $eauth->redirectUrl = Yii::app()->user->returnUrl;
            $eauth->cancelUrl = $this->createAbsoluteUrl('site/login');

            try {
                if ($eauth->authenticate()) {
                    //var_dump($eauth->getIsAuthenticated(), $eauth->getAttributes());
                    $identity = new EAuthUserIdentity($eauth);

                    // successful authentication
                    if ($identity->authenticate()) {
                        Yii::app()->user->login($identity);
                        //var_dump($identity->id, $identity->name, Yii::app()->user->id);exit;

                        // special redirect with closing popup window
                        $eauth->redirect();
                    }
                    else {
                        // close popup window and redirect to cancelUrl
                        $eauth->cancel();
                    }
                }

                // Something went wrong, redirect to login page
                $this->redirect(array('site/login'));
            }
            catch (EAuthException $e) {
                // save authentication error to session
                Yii::app()->user->setFlash('error', 'EAuthException: '.$e->getMessage());

                // close popup window and redirect to cancelUrl
                $eauth->redirect($eauth->getCancelUrl());
            }
        }

        // default authorization code through login/password ..
    }
