*/
protected $userProvider;
/**
* #InjectParams({

$this->userProvider = $userProvider;
}
public function createToken(Request $request, $providerKey)
{
$user = $request->getSession()->get('sso_user');
if (!$user) {
throw new BadCredentialsException('No user found');
}
return new PreAuthenticatedToken(
'anon.', $user, $providerKey
);
}
public function authenticateToken(TokenInterface $token, UserProviderInterface $userProvider, $providerKey)
{
$user = $token->getCredentials();
if (!is_array($user)) {
$user = $token->getUser();
}
if (!$user) {
throw new AuthenticationException('User does not exist.');
}
$ssoUser = $this->userProvider->loadUser($user);
return new PreAuthenticatedToken(
$ssoUser, $user, $providerKey, $ssoUser->getRoles()
);
}
public function supportsToken(TokenInterface $token, $providerKey)

}
}

Answer 1

i set the login path to logout path like this:
secured_area:
form_login:
login_path : main_user_logout
then i wrote custom logout handler:
/**
* #Service("sso_authentication_handler")
*/
class SsoAuthenticationHandler implements LogoutSuccessHandlerInterface
{
/**
* #var Router
*/
private $router;
/**
* #var array
*/
protected $ssoUrls;
/**
* #InjectParams({
* "ssoUrls" = #Inject("%wordpress_sso%"),
* "router" = #Inject("router")
* })
*/
public function __construct(array $ssoUrls, Router $router)
{
$this->ssoUrls = $ssoUrls;
$this->router = $router;
}
public function onLogoutSuccess(Request $request)
{
$locale = $request->getLocale();
if ($locale === 'pl') {
$url = $this->ssoUrls[$locale];
} else {
$url = $this->ssoUrls['en'];
}
$url .= '?returnUrl=' . $this->router->generate('main');
return new RedirectResponse($url);
}
}
so with this combination i achive behavior like when youser is not authenticated or when he logout i will redirect him to other site to login, in my example to wordpress.
