FOSUserBundle MappingException

Я развертывал систему с Symfony2, FOSUserBundle & Fr3dLdapBundle, но я получил следующую проблему:

MappingException: Class "XXX\Shared\XXXUserBundle\Entity\User" sub class of "FOS\UserBundle\Model\User" is not a valid entity or mapped super class.

Вот объясняется, что eAccelerator не совместим, но у меня его нет:

Также пробовал в недавней версии PHP, но проблема сохраняется:

На моей локальной системе Windows с Xammp 1.7.7 (PHP 5.3.8) все работает отлично !.

C: \ XAMPP \ HTDOCS \ Symfony2 \ SRC \ Xyz \ Shared \ XYUserBundle \ Entity \ User.php

Примечание: Xyz и XYUserBundle представляют фактическую прописную букву текста.

User.php выглядит следующим образом:

<?php
namespace Xyz\Shared\XYUserBundle\Entity;

use FOS\UserBundle\Model\User as BaseUser;
use FR3D\LdapBundle\Model\LdapUserInterface;

/**
* User
*/
class User extends BaseUser implements LdapUserInterface
{

// Esta variable sirve para almacenar (cache) la ruta del usuario en el LDAP
protected $dn;

protected $employeeid;

/**
* Set Ldap Distinguished Name
*
* @param string $dn Distinguished Name
*/
public function setDn($dn){
$this->dn = $dn;

return $this;
}

/**
* Get Ldap Distinguished Name
*
* @return string Distinguished Name
*/
public function getDn(){
return $this->dn;
}public function setEmployeeid($employeeid)
{
$this->employeeid = $employeeid;

return $this;
}

public function getEmployeeid(){
return $this->employeeid;
}

public function serialize()
{
return serialize(array(
$this->password,
$this->salt,
$this->usernameCanonical,
$this->username,
$this->emailCanonical,
$this->email,
$this->expired,
$this->locked,
$this->credentialsExpired,
$this->enabled,
$this->id,
$this->roles,
$this->dn,
));
}

public function unserialize($serialized)
{
list(
$this->password,
$this->salt,
$this->usernameCanonical,
$this->username,
$this->emailCanonical,
$this->email,
$this->expired,
$this->locked,
$this->credentialsExpired,
$this->enabled,
$this->id,
$this->roles,
$this->dn,
) = unserialize($serialized);
}

}

В чем может быть проблема?
