Cakephp $this->Auth->loggedIn() doesnt always work

Question

I am using cakephps Auth Component to login to my site. When I correctly enter in my username and password, it will log me in. Then when I use loggedIn() to check that I am logged in, it is very inconsistent in returning true. This is my AppController where I set loggedIn() to a variable to use later:

<?php

App::uses('Controller', 'Controller');
App::uses('File', 'Utility');
App::uses('AuthComponent', 'Component');

class AppController extends Controller {
    public $components = array(
        'Session',
        'Auth'=>array(
            'loginRedirect'=> array('controller'=>'users', 'action'=>'index'),
            'logoutRedirect'=> array('controller'=>'users', 'action'=>'index'),
            'authError' =>"You can't access that page",
            'authorize'=> array('Controller')
        )

    );
    //determines what logged in users have access to
    public function isAuthorized($user){
        return true;
    }
    //determines what non-logged in users have access to
    public function beforeFilter(){
        $this->Auth->allow('index','view');
        $this->set('logged_in', $this->Auth->loggedIn());
        $this->set('current_user', $this->Auth->user());
    }


}

And here is a bit of my code where I use 'logged_in'

<?php if($logged_in): ?> //this only returns true some of the time
      Welcome <?php echo $current_user['username']; ?>. <?php echo  $this->Html->link('Logout', array('controller'=>'users', 'action'=>'login')); ?>

<?php else: ?>
   <?php echo  $this->Html->link('Login', array('controller'=>'users', 'action'=>'logout')); ?>
<?php endif; ?>

And here is my login():

public function login(){
    if($this->request->is('post')){
        if($this->Auth->login()){  //this returns true every time
            $this->redirect($this->Auth->redirect());

        }else{
            $this->Session->setFlash('Your username and/or password is incorrect');
        }
    }

}

I have tried calling $this->Auth->loggedIn() instead of using $logged_in but I get the error that the Auth Helper cannot be found. Please let me know if there is any more information needed to answer my question.

Just look if there there is an authenticated with your var current_user — Hugo Dozois

Move these lines to beforeRender()

    $this->set('logged_in', $this->Auth->loggedIn());
    $this->set('current_user', $this->Auth->user());

Besides that, nothing seems wrong with your code. The comment that Auth->login() would always return true only happens when you pass any argument to the login() method, which the code you show doesnt have though.
