Secured authentification for users symfony2 - symfony

Question

I use symfony2 in my project, i have an entity employee that includes all informations of the emlpolyee and also the username and password to do the login to his session. i want to create a secured authentification to the employee but when i check the documentation of FOS Userbundle and SonataUserBundle i see that i should create a new entity USER that includes new usernames and passwords. but i want to use usernames and passwords stored in my entity employee. this is my entity:
employee.php
class employee
{
private $codeEmployee;
//////
private $username;
private $password;
public function getCodeEmployee()
{
return $this->codeEmployee;
}
/////
public function setusername($username)
{
$this->username = $username;
return $this;
}
public function getusername()
{
return $this->username;
}
public function setPassword($password)
{
$this->password = $password;
return $this;
}
public function getPassword()
{
return $this->password;
}
////////
}
how to do that??

Answer 1

The official documentation explains the procedure to do that.
Your Employee class must extend the base User class :
<?php
namespace Foo\BarBundle\Entity;
use FOS\UserBundle\Model\User as BaseUser;
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Entity
* #ORM\Table(name="employees")
*/
class Employee extends BaseUser
{
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #ORM\Column(type="string", length=255)
*/
protected $codeEmployee;
// Optional
public function __construct()
{
parent::__construct();
// your own logic
}
public function getCodeEmployee()
{
return $this->codeEmployee;
}
public function setCodeEmployee($codeEmployee)
{
$this->codeEmployee = $codeEmployee;
return $this;
}
}
Don't forget to configure FOSUserBundle to choose your user class :
# app/config/config.yml
fos_user:
db_driver: orm
firewall_name: main
user_class: Foo\BarBundle\Entity\Employee
The rest of the configuration (security.yml file, the FOSUserBundle routing files and the other commands to launch) is explained is the documentation.
The documentation also explain how to extend the User entity and to override the form.
