Auth not logging in (CakePHP 2.7.5) - php

Question

I have a CakePHP app that I am trying to upgrade from 1.3 to 2.7.5 and I can hit the log in page but when I go to log in, it doesn't do anything, no errors, just basically refreshes the page. I am really confused why this is happening and would greatly appreciate any help I could get. I did post another question about this but deleted it because it did not provide enough of the code to solve the problem. I have included the AppController as well as the Users controller below.
AppController.php
?php
class AppController extends Controller {
var $components = array('Auth', 'Session', 'RequestHandler');
var $uses = array('Tour');
function beforeFilter() {
$this->setLayout();
$this->Auth->loginRedirect = array('controller' => 'users', 'action' => 'find_home');
$this->Auth->autoRedirect = false;
if ($this->Session->check('Auth.User.userid')) {
$tour = $this->Tour->findByUserid($this->Session->read('Auth.User.userid'));
$user = $this->Auth->user();
$tour = $this->Tour->findByUserid($user['User']['userid']);
$user['Tour'] = $tour['Tour'];
$this->set('user', $user);
}else if (isset($_GET['token'])) {
$tour = $this->Tour->read(null, $_GET['token']);
if ($tour) {
$tour['Tour']['sessionmodified'] = date('Y-m-d H:i:s');
$this->Tour->save($tour);
$this->set('user', $tour);
}
}
}
private function setLayout() {
if (array_key_exists('prefix', $this->params)) {
if ($this->params['prefix'] == 'admin') {
$this->layout = 'admin';
}else if ($this->params['prefix'] == 'teacher') {
$this->layout = 'teacher';
}
}
}
}
?>
UserController.php
function login() {
if (!empty($this->data) && $this->Auth->user()) {
// Delete all old tokens
$this->Tour->recursive = -1;
$this->Tour->deleteAll(array('Tour.userid' => $this->Auth->user('userid')));
// Create a new token
$this->Tour->create();
$this->Tour->save(array('token' => md5(rand()), 'userid' => $this->Auth->user('userid')));
// Update login count
$user = $this->User->read(null, $this->Auth->user('userid'));
$user['User']['logincount']++;
$this->User->saveField('logincount', $user['User']['logincount']);
// Update last login time
$this->User->saveField('lastlogin', date('Y-m-d h:m:s'));
$this->redirect($this->find_home());
}
}
function logout() {
if (!empty($this->data) && $this->Auth->user()) {
// Delete any tours
$this->Tour->recursive = -1;
$this->Tour->deleteAll(array('Tour.userid' => $this->Auth->user('userid')));
}
$this->redirect($this->Auth->logout());
}
function index() {
$this->layout = false;
$this->autoRender = false;
Configure::write('debug', 0);
ini_set('soap.wsdl_cache_enabled', '0');
$server = new SoapServer('http://' . $_SERVER['HTTP_HOST'] . $this->webroot . 'users/wsdl');
$server->setClass('User');
$server->handle();
