User login null error - cakephp

Question

I am using cakephp 2.1 and I used login action in UsersController as follows.
public function login() {
if ($this->request->is('post')) {
if ($this->Auth->login()) {
$this->redirect($this->Auth->redirect());
} else {
$this->Session->setFlash('Invalid email or password, try again', 'default/flash_error');
}
}
}
And the login.ctp code is as follows.
<?php echo $this->Form->create('User', array('class' => 'form')); ?>
<div class="control-group">
<label class="control-label" for="inputEmail">Email</label>
<div class="controls">
<?php echo $this -> Form -> text('email', array('id' => 'inputEmail', 'placeholder' => 'Email')); ?>
<?php echo $this -> Form -> error('email', null, array('wrap' => 'span', 'class' => 'help-block')); ?>
</div>
</div>
<div class="control-group">
<label class="control-label" for="inputPassword">Password</label>
<div class="controls">
<?php echo $this -> Form -> password('password', array('id' => 'inputPassword', 'placeholder' => 'Password')); ?>
<?php echo $this -> Form -> error('password', null, array('wrap' => 'span', 'class' => 'help-block')); ?>
</div>
</div>
<div class="control-group">
<div class="controls">
<label class="checkbox">
<input type="checkbox"/>
Remember me </label>
<?php echo $this->Form->button('Sign in', array('type' => 'submit', 'class' => 'btn')); ?>
</div>
</div>
<?php echo $this->Form->end(); ?>
When the form get submitted with email and password, the user is not able to login so its showing an error 'Invalid email or password, try again'. Even I am passing the $this->request->data['User'] into $this->Auth->login() method and debugged $this->Session->read(Auth.User.id). Its giving me null. Please give me a solution for this.

You can try passing $this->request->data into the $this->Auth->login() method. It's not a great way to do it (see this post: CakePHP Auth Component Not logging in when using $this->Auth->login();), but it works for me. Have you debugged $this->Auth->login()?
