@shivakumar , this can help you … refer it.

step : 1

first you have to override id using getId() function , I post here working code of components folder , UserIdentity file ,

class UserIdentity extends CUserIdentity


   private $_id;

   public function authenticate()


       $record=Employee::model()->findByAttributes(array('E_EMAIL'=>$this->username));  // here I use Email as user name which comes from database



                       $this->_id='user Null';



       else if($record->E_PASSWORD!==$this->password)            // here I compare db password with passwod field

               {        $this->_id=$this->username;



	 else if($record['E_STATUS']!=='Active')                //  here I check status as Active in db


			   		$err = "You have been Inactive by Admin.";

			        $this->errorCode = $err;






	   $this->setState('title', $record['E_NAME']);



       return !$this->errorCode;


   public function getId()


       return $this->_id;



step : 2

here is code for models folder LoginForm file ,

public function authenticate($attribute,$params)




			$this->_identity=new UserIdentity($this->username,$this->password);


				$this->addError('password','Incorrect username or password.');



step : 3

code for controller file ,

public function actionLogin()


		$model=new LoginForm;

		$empModel = new Employee;   //  for validating different user to redirect different pages

		if(isset($_POST['ajax']) && $_POST['ajax']==='login-form')


			echo CActiveForm::validate($model);








			if($model->validate() && $model->login())


				$empData = $empModel->getEmpLoginData($_POST['LoginForm']['username']);   // get employee data from database comparing username ( in my case email )

				$eid = $empData[0]['E_ID'];          

				if($empData[0]['E_ROLE']=='Admin'){        //  checking user is Admin or not

					$this->redirect(array("admin_home_page_here"));    //  redirect to admin page


					$this->redirect(array("user_page_here"));   //  redirect normal user page
