set FOSUSERBUNDLE with existing table user (in symfony2) - php

Question

I am supposed to built a project with symfony2 for a back end, and angular2 for front end.
For handling user action(authentification,remember me ...) I'am trying to used FOSUSERBUNDLE.
Let me specify that I'am using and existing database which contains a table with many attributes like (id, category, title, name, email, number, adress, ...). Some of attributes are not the same User in FOSUSERBUNDLE.
My question is how can I set FOSUSERBUNDLE to make it work with my existing table without brook it?
When I extend my class customer to BaserUser of FOSUserbundle it broke and changed my table structure
below
<?php
// src/AppBundle/Entity/User.php
namespace AppBundle\Entity;
use FOS\UserBundle\Model\User as BaseUser;
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Entity
* #ORM\Table(name="fos_user")
*/
class customer extends BaseUser
{
/**
* #var float
*
* #ORM\Column(name="scoring", type="float", precision=10, scale=0, nullable=false)
*/
private $scoring = '0';
/**
* #var integer
*
* #ORM\Column(name="id_type", type="integer", nullable=false)
*/
private $idType = '4';
/**
* #var integer
*
* #ORM\Column(name="id_categorie", type="integer", nullable=false)
*/
private $idCategorie = '0';
/**
* #var string
*
* #ORM\Column(name="autorisation_prelevement", type="string", nullable=false)
*/
private $autorisationPrelevement = 'N';
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #ORM\Column(type="string")
*/
protected $addresse;
public function __construct()
{
parent::__construct();
}
}
