### I wish get some related good snippet codes for solving the issue and return a " Login Sucessfull "

Code to reproduce the issue

namespace Users\Controller;

use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;

use Zend\Authentication\AuthenticationService;
use Zend\Authentication\Adapter\DbTable as DbTableAuthAdapter;

use Users\Form\LoginForm;
use Users\Form\LoginFilter;

use Users\Model\User;
use Users\Model\UserTable;



class LoginController extends AbstractActionController
{
    protected $storage;
    protected $authservice;
    
    public function getAuthService()
    {
        if (! $this->authservice) {
            $this->authservice = $this->getServiceLocator()->get('AuthService');
        }
        
        return $this->authservice;
    }
    
    public function logoutAction()
    {
        $this->getAuthService()->clearIdentity();
        
        return $this->redirect()->toRoute('users/login');
    }
    
    public function indexAction()
    {
        $form = $this->getServiceLocator()->get('LoginForm');
        $viewModel  = new ViewModel(array('form' => $form));
        return $viewModel;
    }
    
    public function processAction()
    {
        if (!$this->request->isPost()) {
            return $this->redirect()->toRoute('users/login');
        }
        
        $post = $this->request->getPost();
        
        $form = $this->getServiceLocator()->get('LoginForm');
        $userTable = $this->getServiceLocator()->get('UserTable');
        
        $form->setData($post);
        if (!$form->isValid()) {
            $model = new ViewModel(array(
                'error' => true,
                'form'  => $form,
            ));
            $model->setTemplate('users/login/index');
            return $model;
        } else {
            //check authentication...
            $this->getAuthService()->getAdapter()
            ->setIdentity($this->request->getPost('email'))
            ->setCredential($this->request->getPost('password'));
            $result = $this->getAuthService()->authenticate();
            if ($result->isValid()) {
                $this->getAuthService()->getStorage()->write($this->request->getPost('email'));
                return $this->redirect()->toRoute('users/login', array(
                    'action' =>  'confirm'
                ));
            } else {
                $model = new ViewModel(array(
                    'error' => true,
                    'form'  => $form,
                ));
                $model->setTemplate('users/login/index');
                return $model;
            }
        }
    }
    
    public function confirmAction()
    {
        $this->layout('layout/myaccount');
        $user_email = $this->getAuthService()->getStorage()->read();
        $viewModel  = new ViewModel(array(
            'user_email' => $user_email
        ));
        return $viewModel;
    }
    
}

I'm sorry this is the wrong place for your question. Please use the forum and add also your configuration which includes the definition for the UserTable class.
