CakePHP: Warning (512): Model "User" is not associated with model "User" Windows to Ubuntu Deployment

Question

I am trying to deploy a cakePHP app which works exactly as it should in Windows. I use an LdapUser model to authenticate through Active Directory:

LdapUser:

<?php
class LdapUser extends AppModel
{
var $name = 'LdapUser';
var $useTable = false;

var $myCompany_ldap = "x.x.x.x";
//var $myCompany_ldap_config = array ('basedn' => 'CN=x,DC=x,DC=x');
var $basedn = 'CN=x,DC=x,DC=x';
var $myCompany_ldap_domain = "x.x";
 //  var $user       = "x@x.x";
 // var $pass       = "x!"; 
var  $exists = false;
var $ds;


function __construct()
{
parent::__construct();

ini_set('max_execution_time', 300); //300 seconds = 5 minutes
$this->ds=ldap_connect( $this->myCompany_ldap );

// print_r($this->basedn);
// debug($this->ds);
// print_r($this->ds);

ldap_set_option($this->ds, LDAP_OPT_PROTOCOL_VERSION, 3);

print_r($this->res);

//debug($this->exists);
//print_r($this->exists);
}

function __destruct()
{

    ldap_close($this->ds);
   // $this->loadModel('Cookie');
  //  $this->Cookie->destroy();
} 


function isConnected(){


    return ldap_bind($this->ds, $this->basedn);

}



function isLdapUser($user, $pass){

     $this->exists = ldap_bind($this->ds, $user, $pass);
    // debug($this->exists);
     //debug($user);
    // debug($pass);
        return $this->exists;

  } 

 } 

And then in UserController inside login function:

    // Login User
public function login() {

    // Check if the user is already logged in
    if ($this->Session->check('Auth.User.id')){ 

        // Redirect to login page
        $this->redirect($this->Auth->loginRedirect); 
    }
    else{
        // If the user is not logged in


        session_set_cookie_params(0); 

        // If the request is a POST request
        if ($this->request->is('post')) { 
            //get credentials
            $this->username = $this->request->data['User']['username'];
            $this->password = $this->request->data['User']['password'];
            $this->domain = $this->request->data['User']['domain'];
            //debug($this->username);
            debug($this->domain) ;

            if ($this->Auth->login() ) { 
                // Successful login
                //Check if specific user exists in LDAP:
                $this->loadModel('LdapUser');

                $this->ds = $this->LdapUser->isConnected();
                //print_r('Ldap status: '. $this->ds);
                //debug($this->ds) ;
                //echo $this->ds;

                $this->isLdapUser =
                                     $this->LdapUser->isLdapUser($this->username .

                //debug($this->isLdapUser);
if ( $this->username =='tsc' || $this->ds  ){ 
if ($this->isLdapUser ||     'tsc' ) {
// Get all the user information and store in Session
$this->User->id = $this->Auth->user('id');
$this->User->contain(array('User', 'Role' => array('Ui', 'Action.name')));
$this->Session->write('User', $this->User->read());

$actions = array();
foreach ($this->Session->read('User.Role.Action') as $key => $value){
     array_push($actions, $value['name']);
                        }
$this->Session->write('User.Role.Action', $actions);

// Render different layout depending on user type
if($this->Session->read('User.Role.Ui.name') == Configure::read('usertype.msp')){
    $this->Session->write('SessionValues.ui', Configure::read('usertype.msp'));
$this->Auth->loginRedirect = array('controller' => 'PortStats', 'action' => 
    'index');
}
else if($this->Session->read('User.Role.Ui.name') == 
    Configure::read('usertype.tsc')){
     $this->Session->write('SessionValues.ui', Configure::read('usertype.tsc'));

$this->Auth->loginRedirect = array('controller' => 'PortStats', 'action' => 
    'index');
}
else if($this->Session->read('User.Role.Ui.name') == 
    Configure::read('usertype.superAdminUserType')){
$this->Auth->loginRedirect = array('controller' => 'uis', 'action' => 'index');
                        }

    // Redirect to main login page
    $this->redirect($this->Auth->loginRedirect);


}
else {
// Failed login
session_destroy();
$this->Session->setFlash(__('Login failed: access not granted'), 'default', 
    array(), 'fail');

    }

    }
else {


// Failed login
session_destroy();
$this->Session->setFlash(__('Login failed: LDAP out of reach'), 'default', 
array(), 'fail');               
}
} 
else { 

// Failed login
$this->Session->setFlash(__('Invalid username or password, please try again'), 
'default', array(), 'fail');                
            }
        }
    }
}

I get:

    Warning (2): ldap_bind() [http://php.net/function.ldap-bind]: Unable to bind to    
    server: Invalid credentials [APP/Model/LdapUser.php, line 56]

My guess is that could be something with case sensitivity between platofrms but it's really bothering that doesn't work in Ubuntu....

[Edited] There is my User model:

[Edit]: I tend to believe the warning is not responsible for my problem: It occurs in both platforms but shouldn't interrupt the site's funcionality.

So when in windows in debug level = 2 I see:

But then in ubuntu, it looks buggy all I get is this screen:

Answer 1

About the 512 associated error:

$this->User->contain(array('User', 'Role' => array('Ui', 'Action.name')));

Change to:

$this->User->contain(array('Role' => array('Ui', 'Action.name')));

Don't contain the model itself.

About the LDAP error, seems to be this line:

$this->exists = ldap_bind($this->ds, $user, $pass);

I would start with some code like this to debug:

var_dump($this->ds);
var_dump($user);
var_dump($pass);
$this->exists = ldap_bind($this->ds, $user, $pass);

Copy-paste this data into some LDAP tool and first verify they are correct.

Try this function to get more error information: http://php.net/manual/en/function.ldap-error.php

Answer 2

OK, mystery solved:

The warning had nothing to do with this:

This line of code is error-proning:

if ($this->isLdapUser ||     'tsc' ) {
.......

user tsc is admin in local db and doesn't exist in ldap so is certain to get a time out from ldap_bind, Looks like Ubuntu platform would crash my application on browser timeout. In contrary my local machine will wait during time out time and continue with log-in.

I just modified my code so admin user 'tsc' will log-in directly without passing from ldap auth.
