Symfony2 (.7) : Users in firewall with active directory - php

Question

I searched for this kind of connection but all the bundles do not work with symfony security 2.7 (Composer says packages problems) and symfony 3.0.
Note : I actually use Silex Framework.
I want to return a true or false response if the user is connected to the active directory.
I have this code for tests :
$app->register(new Silex\Provider\SecurityServiceProvider(), array(
'security.firewalls' => array(
'login' => array(
'pattern' => '^/login$',
),
'secured' => array(
'pattern' => '^/',
'anonymous' => false,
'logout' => true,
'form' => array('login_path' => '/login', 'check_path' => '/login_check'),
'users' => array(
// raw password is foo
'admin' => array('ROLE_ADMIN', '5FZ2Z8QIkA7UTZ4BYkoC+GsReLf569mSKDsfods6LYQ8t+a8EW9oaircfMpmaLbPBh4FOBiiFyLfuZmTSUwzZg=='),
),
),
),
));
The login with admin & foo worked but that's not what I want.
I want to replace this part of code :
'users' => array(
// raw password is foo
'admin' => array('ROLE_ADMIN', '5FZ2Z8QIkA7UTZ4BYkoC+GsReLf569mSKDsfods6LYQ8t+a8EW9oaircfMpmaLbPBh4FOBiiFyLfuZmTSUwzZg=='),
),
Or any others solutions to replace the value who allows the user to bypass the firewall and enter in the application.
Note :
I use adLDAP plugin to test the connection with the Active Directory (It's works perfectly).

Answer 1

Try to use LdapUserProvider for it. Remove 'users' => array(...) from secured config and add user provider definition for this zone.
$app['security.user_provider.secured'] = $app->share(function($app) {
return new \Symfony\Component\Security\Core\User\LdapUserProvider(
new \Symfony\Component\Ldap\LdapClient('ldap.server.com'),
'baseDn', // ex.: dc=example,dc=com
'searchDn' // ex.: CN={username},DC=example,DC=com
);
});
Or you can write your own user provider based on LdapUserProvider and adLDAP. Something like this:
namespace My\Namespace;
use Symfony\Component\Security\Core\User\LdapUserProvider;
use Symfony\Component\Security\Core\User\User;
class adLdapUserProvider extends LdapUserProvider
{
public function loadUserByUsername($username)
{
// you code, that returns user from ldap server
// $this->ldap - is object of adLDAP
$user = $this->ldap->user()->info($username);
return $this->loadUser($username, $user);
}
}
and change user provider definition
$app['security.user_provider.secured'] = $app->share(function($app) {
return new \My\Namespace\adLdapUserProvider(
new \adLDAP\adLDAP(...)
);
});
