Symfony 6.4 project (started with on the official doc)

The only purpose is to demonstrate the problem with the custom_authenticators setting in the firewall

---

To run the project you need :

- php 8.1 (or higher)
- composer

Installation steps :

clone the project
cd into it 

$ composer install
$ php bin/console doctrine:schema:create
$ php bin/console doctrine:fixture:load

Run with symfony cli or in a server :
$ symfony server:start

What I what to achieve is :

• when an anonymous user access / => display the page
• when a logged-in user try to access / , he should be redirected. This means I need to know if he's logged in (so an exception in the firewall is not a solution)

This is why an access_control has been set in the config/security.yml file :

access_control:
- { path: ^/$, roles: PUBLIC_ACCESS }

This works fine when setting form_login instead of the custom_authenticators

It seems like :
In the custom_authenticators does not take the access_control rules.
This means access to the homepage '/' can not be done anonymously.

I can not find the option or param in the firewall to do so.
Does it come from the App\Security\CustomAuthenticator file and the supports() function ?
