Authenticator does not support the request - docker

Question

I have a Symfony 5.1 project that has login functionality.
When I use the Symfony CLI command symfony serve, the login on localhost just works.
But when I try the same login via Docker, nothing happens.
In the logs of my nginx container, I can see this message:
172.19.0.1 - - [24/Nov/2020:13:31:40 +0000] "POST /login HTTP/1.1" 302 282 "http://localhost:8088/login" "Mozilla/5.0 (Macintosh; Intel Mac OS X 11_0_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/87.0.4280.67 Safari/537.36"
2020/11/24 13:31:41 [error] 27#27: *122 FastCGI sent in stderr: "PHP message: [info] Matched route "app_login".
PHP message: [debug] Checking for authenticator support.
PHP message: [debug] Checking support on authenticator.
PHP message: [debug] Authenticator does not support the request. ['firewall_name' => 'main', 'authenticator' => 'Symfony\Component\Security\Guard\Authenticator\GuardBridgeAuthenticator']
This is my config/packages/security.yaml:
security:
enable_authenticator_manager: true
providers:
users:
entity:
class: 'App\Entity\User'
encoders:
App\Entity\User:
algorithm: auto
firewalls:
dev:
pattern: ^/(_(profiler|wdt)|css|images|js)/
security: false
main:
anonymous: false
lazy: true
provider: users
guard:
authenticators:
- App\Security\LoginFormAuthenticator
logout:
path: app_logout
# where to redirect after logout
target: home
role_hierarchy:
ROLE_ADMIN: ROLE_USER
access_control:
- { path: ^/admin, roles: ROLE_ADMIN }
This is my docker/nginx/default.conf:
server {
listen 80;
index index.php index.html;
server_name localhost;
error_log /var/log/nginx/error.log;
access_log /var/log/nginx/access.log;

proxy_buffer_size 128k;
proxy_buffers 4 256k;
proxy_busy_buffers_size 256k;
location / {
try_files $uri $uri/ /index.php?$query_string;
}
location ~ \.php$ {
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass php:9000;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_buffer_size 128k;
fastcgi_buffers 4 256k;
fastcgi_busy_buffers_size 256k;
}
}
This is my docker/php/Dockerfile:
FROM php:7.4-fpm
# Install Composer
RUN curl -sS https://getcomposer.org/installer | php -- \
--install-dir=/usr/local/bin \
--filename=composer
# Install MySQL
RUN docker-php-ext-install mysqli pdo pdo_mysql
WORKDIR /var/www/app
And my src/Security/LoginFormAuthenticator.php:
<?php
namespace App\Security;
...
use App\Entity\User;
...
class LoginFormAuthenticator extends AbstractFormLoginAuthenticator implements PasswordAuthenticatedInterface
{
use TargetPathTrait;
public const LOGIN_ROUTE = 'app_login';
private $entityManager;
private $urlGenerator;
private $csrfTokenManager;
private $passwordEncoder;
public function __construct(EntityManagerInterface $entityManager, UrlGeneratorInterface $urlGenerator, CsrfTokenManagerInterface $csrfTokenManager, UserPasswordEncoderInterface $passwordEncoder)
{
$this->entityManager = $entityManager;
$this->urlGenerator = $urlGenerator;
$this->csrfTokenManager = $csrfTokenManager;
$this->passwordEncoder = $passwordEncoder;
}
public function supports(Request $request)
{
return self::LOGIN_ROUTE === $request->attributes->get('_route')
&& $request->isMethod('POST');
}
public function getCredentials(Request $request)
{
$credentials = [
'email' => $request->request->get('email'),
'password' => $request->request->get('password'),
'csrf_token' => $request->request->get('_csrf_token'),
];
$request->getSession()->set(
Security::LAST_USERNAME,
$credentials['email']
);
return $credentials;
}
public function getUser($credentials, UserProviderInterface $userProvider)
{
$token = new CsrfToken('authenticate', $credentials['csrf_token']);
if (!$this->csrfTokenManager->isTokenValid($token)) {
throw new InvalidCsrfTokenException();
}
$user = $this->entityManager->getRepository(User::class)->findOneBy(['email' => $credentials['email']]);
if (!$user) {
// fail authentication with a custom error
throw new CustomUserMessageAuthenticationException('Email could not be found.');
}
return $user;
}
public function checkCredentials($credentials, UserInterface $user)
{
return $this->passwordEncoder->isPasswordValid($user, $credentials['password']);
}
public function getPassword($credentials): ?string
{
return $credentials['password'];
}
public function onAuthenticationSuccess(Request $request, TokenInterface $token, string $providerKey)
{
if ($targetPath = $this->getTargetPath($request->getSession(), $providerKey)) {
return new RedirectResponse($targetPath);
}
return new RedirectResponse($this->urlGenerator->generate('home'));
}
protected function getLoginUrl()
{
return $this->urlGenerator->generate(self::LOGIN_ROUTE);
}
}
What am I doing wrong that my Docker isn't recognizing my App\Security\LoginFormAuthenticator as Authenticator?
Thanks in advance!
EDIT: 22 February 2021
It looks like the form is redirecting itself without errors. I guess the the wrong Authenticator was used, but in my security.yaml file you see the correct guard.

Answer 1

Removing the anonymous: false setting did the trick.
Thanks #Cerad for your help!
