        }
        public function login() {
            if($this->Session->read('Auth.User')){
                $this->redirect($this->Auth->redirect());
            }
            if ($this->request->is('post')) {
                print_r($this->request->data['User']['password']);
                $encPassword = AuthComponent::password($this->request->data['User']['password']);
                $this->request->data['User']['password'] = $encPassword;
                print_r($this->request->data['User']['password'].' - '.$this->request->data['User']['username']);
                //print_r($_SESSION);

        }

        public function index() {
            $this->User->recursive = 0;
            $this->set('users', $this->Paginator->paginate());
        }

        public function view($id = null) {
            if (!$this->User->exists($id)) {
                throw new NotFoundException(__('Invalid user'));
            }
            $options = array('conditions' => array('User.' . $this->User->primaryKey => $id));
            $this->set('user', $this->User->find('first', $options));
        }

        public function edit($id = null) {
            if (!$this->User->exists($id)) {
                throw new NotFoundException(__('Invalid user'));
            }
            if ($this->request->is(array('post', 'put'))) {
                if ($this->User->save($this->request->data)) {
                    $this->Session->setFlash(__('The user has been saved.'));
                    return $this->redirect(array('action' => 'index'));
                } else {
                    $this->Session->setFlash(__('The user could not be saved. Please, try again.'));
                }

Answer 1

the problem is in the encryptacion of your passwords, see if you're doing a beforesave and also are making a encryption when saving is like you are doing a double encryption of your password and password that you log in to verify if they are the same in your DB

UsersController

    public function beforeFilter() {
        parent::beforeFilter();
    }
    public function login() {
        if($this->Session->read('Auth.User')){
            $this->redirect($this->Auth->redirect());
        }
        if ($this->request->is('post')) {
            if ($this->Auth->login()) {
                return $this->redirect($this->Auth->redirect());
            }
            $this->Session->setFlash(__('Invalid username or password, try again'));
        }
    }

User model

 public function beforeSave($options = array()) {
    // hash our password

    if (!$this->id) {
        $passwordHasher = new SimplePasswordHasher();
        $this->data['User']['password'] = $passwordHasher->hash($this->data['User']['password']);
    }
    return true;
}

AppController

public function beforeFilter() {
    Security::setHash('sha1');
    $this->Auth->allow('index', 'display', 'view');
}

In your database right is that the password field is varchar (30)
