Why password doesn't be authenticated in LoginForm model

This is my LoginForm model:


class LoginForm extends CFormModel


	public $username;

	public $password;

	private $_identity;

	function rules()


		return array(

			array("username, password","required"),

			array('password', 'authenticate'),



	public function authenticate($attribute,$params)


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


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




In controller:

				$model = new User;

				$model->attributes = $_POST["User"];

				if ($model->validate())


I tested with some incorrect username and password but validate() function always return "true"

Why ????

Note that you are doing $model=new User… not $model=new LoginForm

This way $model->validate() validates the user model not the LoginForm model…

Oh, that’s error:

$model = new User;
