symfony2 custom User Provider prints "Bad credentials" - symfony

Question

I always get message: "Bad credentials" when I try to login in symfony2. I am doing this based to http://symfony.com/doc/current/cookbook/security/custom_provider.html. Please help me to figure out, where the problem is? Thanks in advance.
security.yml looks like this
security:
encoders:
Zags\UserBundle\Security\User\User: plaintext
role_hierarchy:
ROLE_ADMIN: ROLE_USER
ROLE_SUPER_ADMIN: [ROLE_USER, ROLE_ADMIN, ROLE_ALLOWED_TO_SWITCH]
providers:
webservice:
id: zags_user_provider
firewalls:
dev:
pattern: ^/(_(profiler|wdt)|css|images|js)/
security: false
login_firewall:
pattern: ^/login$
anonymous: ~
secured_area:
pattern: ^/
anonymous: ~
form_login:
login_path: /login
check_path: /login_check
#anonymous: ~
#http_basic:
# realm: "Secured Demo Area"
access_control:
- { path: ^/gender_type, roles: ROLE_USER }
#- { path: ^/_internal/secure, roles: IS_AUTHENTICATED_ANONYMOUSLY, ip: 127.0.0.1 }
I have added these lines to routing.yml
login:
pattern: /login
defaults: { _controller: ZagsUserBundle:Security:login }
login_check:
pattern: /login_check
User.php class looks like this
<?php
namespace Zags\UserBundle\Security\User;
use Symfony\Component\Security\Core\User\UserInterface;
class User implements UserInterface
{
private $username;
private $password;
private $salt;
private $roles;
public function __construct($username, $password, $salt, array $roles)
{
$this->username = $username;
$this->password = $password;
$this->salt = $salt;
$this->roles = $roles;
}
public function getRoles()
{
return $this->roles;
}
public function getPassword()
{
return $this->password;
}
public function getSalt()
{
return $this->salt;
}
public function getUsername()
{
return $this->username;
}
public function eraseCredentials()
{
}
public function equals(UserInterface $user)
{
return $user->getUsername() === $this->username;
}
}
?>
So this is my UserProvider.php class
<?php
namespace Zags\UserBundle\Security\User;
use Symfony\Component\Security\Core\User\UserProviderInterface;
use Symfony\Component\Security\Core\User\UserInterface;
use Symfony\Component\Security\Core\Exception\UsernameNotFoundException;
use Symfony\Component\Security\Core\Exception\UnsupportedUserException;
class UserProvider implements UserProviderInterface
{
public function loadUserByUsername($username)
{
// make a call to your webservice here
$userData = array("username" => "latysh", "password" => "123", "salt" => "123", "roles" => array('ROLE_USER'));
// pretend it returns an array on success, false if there is no user
if ($userData) {
$username = $userData['username'];
$password = $userData['password'];
$salt = $userData['salt'];
$roles = $userData['roles'];
// ...
return new User($username, $password, $salt, $roles);
}
throw new UsernameNotFoundException(sprintf('Username "%s" does not exist.', $username));
}
public function refreshUser(UserInterface $user)
{
if (!$user instanceof User) {
throw new UnsupportedUserException(sprintf('Instances of "%s" are not supported.', get_class($user)));
}
return $this->loadUserByUsername($user->getUsername());
}
public function supportsClass($class)
{
return $class === 'Zags\UserBundle\Security\User\User';
}
}
?>
and services.yml looks like this
parameters:
zags_user_provider.class: Zags\UserBundle\Security\User\UserProvider
services:
zags_user_provider:
class: "%zags_user_provider.class%"
SecurityController.php
<?php
namespace Zags\UserBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\Security\Core\SecurityContext;
class SecurityController extends Controller
{
public function loginAction()
{
$request = $this->getRequest();
$session = $request->getSession();
// get the login error if there is one
if ($request->attributes->has(SecurityContext::AUTHENTICATION_ERROR)) {
$error = $request->attributes->get(SecurityContext::AUTHENTICATION_ERROR);
} else {
$error = $session->get(SecurityContext::AUTHENTICATION_ERROR);
$session->remove(SecurityContext::AUTHENTICATION_ERROR);
}
return $this->render('ZagsUserBundle:Security:login.html.twig', array(
// last username entered by the user
'last_username' => $session->get(SecurityContext::LAST_USERNAME),
'error' => $error,
));
}
}
?>
and login.html.twig
{% if error %}
<div>{{ error.message }}</div>
{% endif %}
<form action="{{ path('login_check') }}" method="post">
<label for="username">Username:</label>
<input type="text" id="username" name="_username" value="{{ last_username }}" />
<label for="password">Password:</label>
<input type="password" id="password" name="_password" />
{#
If you want to control the URL the user is redirected to on success (more details below)
<input type="hidden" name="_target_path" value="/account" />
#}
<button type="submit">login</button>
</form>

Answer 1

Has found answer to my question. Thanks to machour for responce. The problem was with SALT. So I updated the User.php class to
public function getSalt()
{
return '';
}
Then it logs in correctly or I should have encoded password with salt to successfully login. If one know how to do it, please write it as answer, YAHOO ))

Answer 2

$factory = $this->get('security.encoder_factory');
$encoder = $factory->getEncoder($user);
$pass = $encoder->encodePassword($user->getPassword(), $user->getSalt());
