App Controller
public function beforeFilter(){
$this->Auth->autoRedirect = false;
$this->Auth->loginAction = array('controller' => './', 'action' => 'index');
$this->Auth->loginRedirect = array('controller' => 'users', 'action' => 'index');
$this->Auth->logoutRedirect = array('controller' => './', 'action' => './');
$this->Auth->authorize = 'controller';
$this->Auth->authError= 'You need permissions to access this page';
$this->Auth->allow('index');
$this->set('Auth',$this->Auth);
}
UsersController
public function login(){
$id = $this->Auth->user('id');
if(empty($id)){
if($this->request->is('post')){
if($this->Auth->login()){
$this->redirect($this->Auth->redirect());
}else{
$this->Session->setFlash('Invalid Username or password');
}
}
}else{

You pretty much answered your own question here:
Note:- infact it is perfectly working if i change the line to
$this->Auth->loginAction = array('controller' => 'users', 'action' => 'login');
Indeed that would work and that is what it should look like. Right now, you're telling the auth component your loginAction (the action which holds your login logic) is the index action of the ./ controller (which doesn't even exist). I'm assuming you're confusing it with the loginRedirect variable, which is for setting the page to go to after successful authentication.

If you only want Registered Users to Access Your Site you could have something like this... at least, this is how I implement something similar in my site...
In your app_controller file add the following to the beginning of your beforeFilter() function
function beforeFilter(){
//Check if user was able to log in thru Auth using your form in the homepage
if($this->isLoggedIn() == TRUE){
$this->layout = 'default'
}else{
// You can created this layout with a login form and
// whatever else you need except <?php echo $content_for_layout; ?>
// Any registered user will be allowed to login using the form
// and continue on to your site using the default layout
// But it guarantees no one else can see your default site
$this->layout = "unregistered_user"
}
}
On your App_controller.php you can create this function
function isLoggedIn(){
// You can also use $this->Auth->user directly in your App's beforeFilter()
// But I just like to have functions so I can reuse
if($this->Auth->user()){
$loggedin= TRUE;
}else{
$loggedin= FALSE;
}
return $loggedin;
}
I have something similar of my site but is only used when in maintenance mode. I am still developing my site. The only problem I've seen with this way, which I have not yet have time/need to look at, is that my errors are not sent to the layout I want. Supposed a user types in http://www.mydomain.com/inexistentpage then cake transfers them to my default layout. It might be easy to fix, but I havent got time to do that yet.
NOTE: I quickly did this off the top of my head and because of it, this code is untested. However, if you have any issues please let me know and I will test it and post back.

using $this->requestAction(anotherController/action); in the view might call to another controller->action. you must ensure that the another controller->action has the right permissions. or you'll get redirect loop.
solve it by adding $this->auth->allow('action name'); to the another controller page in the beforeFilter() callback.
