loading resource security.yml symfony3

Question

I try to extend my file security.yml in app with my security.yml in my own bundle but I've this error :

InvalidArgumentException in YamlFileLoader.php line 431:
There is no extension able to load the configuration for "security"(in
C:\wamp64\www\Project\src\Admin\UserBundle\DependencyInjection/../Resources/
config\security.yml). Looked for namespace "security", found none

I've looked at the Symfony doc but I don't find the issue. I show u my code

app/Resources/config/security.yml

security:
    encoders:
        Symfony\Component\Security\Core\User\User: plaintext

        - { path: ^/admin, roles: ROLE_ADMIN }

            security: false

                remember_me:
                    secret: %secret%

Admin/UserBundle/DependencyInjection/AdminUserExtension.php

class AdminUserExtension extends Extension
{
    /**
    * {@inheritdoc}
    */
    public function load(array $configs, ContainerBuilder $container)
    {
        $configuration = new Configuration();
        $config = $this->processConfiguration($configuration, $configs);

        $loader = new Loader\YamlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config'));

        foreach ( array('services', 'parameters', 'security') as $basename )
        {
           $loader->load(sprintf('%s.yml', $basename));
        }
    }
}

The SecurityBundle is here :(

AppKernel

<?php

use Symfony\Component\HttpKernel\Kernel;
use Symfony\Component\Config\Loader\LoaderInterface;

class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = [
            new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
            new Symfony\Bundle\SecurityBundle\SecurityBundle(),
            new Symfony\Bundle\TwigBundle\TwigBundle(),
            new Symfony\Bundle\MonologBundle\MonologBundle(),
            new Symfony\Bundle\SwiftmailerBundle\SwiftmailerBundle(),
            new Doctrine\Bundle\DoctrineBundle\DoctrineBundle(),
            new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
            new FOS\UserBundle\FOSUserBundle(),
            new Stof\DoctrineExtensionsBundle\StofDoctrineExtensionsBundle(),
            new Symfony\Bundle\AsseticBundle\AsseticBundle(),
        ];

        if (in_array($this->getEnvironment(), ['dev', 'test'], true)) {
            $bundles[] = new Symfony\Bundle\DebugBundle\DebugBundle();
            $bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();
            $bundles[] = new Sensio\Bundle\DistributionBundle\SensioDistributionBundle();
            $bundles[] = new Sensio\Bundle\GeneratorBundle\SensioGeneratorBundle();
        }

        return $bundles;
    }

    public function getRootDir()
    {
        return __DIR__;
    }

    public function getCacheDir()
    {
        return dirname(__DIR__).'/var/cache/'.$this->getEnvironment();
    }

    public function getLogDir()
    {
        return dirname(__DIR__).'/var/logs';
    }

    public function registerContainerConfiguration(LoaderInterface $loader)
    {
        $loader->load($this->getRootDir().'/config/config_'.$this->getEnvironment().'.yml');
    }
 }

The other file seems to work because when I merge security.yml between them, the application works.

You need to add SecurityBundle to your AppKernel.

    public function registerBundles()
{
    $bundles = [
        ...
        new Symfony\Bundle\SecurityBundle\SecurityBundle(),
        ...
    ];
