Answer 1

I have the same problem. I tried all the suggestion. My Cache engine is Apc.

  $this->__saveData($t);
  debug($this->Session->read());// >>>>>> GOOD
  $this->redirect(array('controller'=>'users','action'=>'main'));
    }
}
 }
  function logout() {
    $this->Session->destroy();
            $this->Session->delete('User');
    $this->redirect(array('controller'=>'logins','action'=>'login'));
}
function forgot() {
$this->layout = 'login';

} 
    private function __saveData($t)
    {   
         $this->Session->write('User',$t['User']['name']);
         $this->Session->write('User_name',$t['User']['firstname']);
         $this->Session->write('User_id',$t['User']['id']);
         $this->Session->write("User_Group",$t['Group']['name']);
         $g = $this->Myauth->getPerm('User_Group'); // This is the array of permission w.r.t to the menu (key)
         $this->Session->write("Permissions",$g);

         debug($this->Session->read());
    }
 function main()
{
    // Check permissions
$this->Myauth->check('users','login');
$username   = $this->Session->read('User');
debug($this->Session->read( ));die(); <<<<< NOTHING

}

The funny thing is that yesterday it worked.

My php.ini has a simple extension=apc.so. My core.php

    Configure::write('Session.defaults', 'php');

Nothing change if I change the Security level. I will appreciate any direction.

EDIT First solution: in my php.ini I had a bad value for session.referer_check (It was = 0 while it should be ''). But now, on the same server, one site is ok. Another one fires the error Error: Call to undefined function apc_cache_info()

The two sites are separated and do not share any cakelib.

[SOLUTION FOUND]

For Cake > 2.2 and Chrome 24 I found this solution (I tried all the others found on the web). In your core.php:

     Configure::write('Security.cookie', 'cakephpfdebackend');
     Configure::write('Session.cookieTimeout', 0);
     Configure::write('Session.checkAgent', false);
     Configure::write('Session.cookie_secure',false);
     Configure::write('Session.referer_check' ,false);
     Configure::write('Session.defaults', 'php'); 

Actually, only the Session.cookieTimeout is required. The other settings are optional to solve the problem.

Answer 2

A possible reason for this problem is that the server clock is not synced with the client's clock and thus the cookie timeouts.

Answer 3

I had some issue with session on some pages . Can you check whether any space comes at the bottom of page after the php ending tag. When i faced this problem, i found session is missing due to a white space character in controller after the php ending tag . Please check this and let me know .

Answer 4

You are overriding the beforeFilter() method. So, instead of using this:

<?php
class UsuariosController extends AppController {

    function beforeFilter() {

    }

you should do this:

<?php
class UsuariosController extends AppController {

    function beforeFilter() {
        parent::beforeFilter();
    }

Answer 5

I was losing session information after a login call too and after searching for a while I found many different ways to fix my issue. I only regret that I don't fully understand what is causing the issue, but I imagine it has to do with php's session configuration.

1. As you mentioned, changing Security.level to low fixed the issue for me Configure::write('Security.level', 'low');
2. Changing the session save configuration to php fixed the issue for me too: Configure::write('Session', array( 'defaults'=>'cake', ));
3. And finally adding a timeout worked too (which I ended up using): Configure::write('Session', array( 'defaults'=>'php', 'cookieTimeout'=> 10000 ));

All these found in /app/Config/core.php

I post this hoping someone is able to make sense of what is going on underneath. I feel understanding the root of the issue would make a better job of answering your question.
