CakePHP 2.0: Login form not working - cakephp-2.0

Question

I m trying to create a new register and login page. I have a problem in login.
1) After I register the Username and Password it is successful hashed and saved into the DB, please find the codes below: (everything is as per cake conventions)
User.php:
<?php
App::uses('AuthComponent', 'Controller/Component');
class User extends AppModel {
......
public function beforeSave() {
if (isset($this->data[$this->alias]['password'])) {
$this->data[$this->alias]['password'] = AuthComponent::password($this->data[$this->alias]['password']);
}
return true;
}
}
?>
UsersController.php:
public function add() {
if ($this->request->is('post')) {
$this->User->create();
if ($this->User->saveAll($this->request->data)) {
$this->Session->setFlash(__('The user has been saved'));
$this->redirect(array('controller' => 'Posts','action' => 'index'));
} else {
$this->Session->setFlash(__('The user could not be saved. Please, try again.'));
}
}
}
public function login() {
if ($this->Auth->login()) {
$this->redirect($this->Auth->redirect());
} else {
$this->Session->setFlash(__('Invalid username or password, try again'), 'default', array(), 'auth');
}
}
public function logout() {
$this->redirect($this->Auth->logout());
}
login.ctp:
<fieldset>
<?php echo $this->Session->flash('auth'); ?>
</fieldset>
<?php echo $this->Form->create('Users');?>
<fieldset>
<?php
echo $this->Form->input('username');
echo $this->Form->input('password');
?>
</fieldset>
<?php echo $this->Form->end(__('Login'));?>
Debug: (debug($this->data);)
From AppController:
Array
(
[Users] => Array
(
[username] => vinodronold
[password] => vinodronold
)
)
From UsersController:
Array
(
[Users] => Array
(
[username] => vinodronold
[password] => vinodronold
)
)
Problem:
Whenever I access /Users/login URL I m getting "Invalid username or password, try again" message.
Also I m unable to login although I m entering the correct username and password.
Please help.
Thanks in advance!!!

Looking at it closer, change your if statement on the login function to this:
if (!empty($this->request->data['User']) && $this->Auth->login()) {
this will fix the instant error message you get when accessing the page.
And I just noticed your form in your view is wrong. Models are singular. Change your form create to:
<?php echo $this->Form->create('User');?>
This should do it for both issues.
