-Authentication Plugin
-=====================
-
-New authentication backends can be written with very few lines of code.
-
-Provider Registration
----------------------
-
-In the method `initialize()` of your plugin, call the method `register()` of the class `AuthenticationManager`:
-
-```php
-public function initialize()
-{
-    $this->authenticationManager->register(new ReverseProxyLdapAuth($this->container));
-}
-```
-
-The object provided to the method `register()` must implement one of the pre-defined authentication interfaces.
-
-Those interfaces are defined in the namepsace `Kanboard\Core\Security`:
-
-- `Kanboard\Core\Security\PreAuthenticationProviderInterface`
-- `Kanboard\Core\Security\PostAuthenticationProviderInterface`
-- `Kanboard\Core\Security\PasswordAuthenticationProviderInterface`
-- `Kanboard\Core\Security\OAuthAuthenticationProviderInterface`
-
-The only requirement is to implement the interfaces, you class can be written the way you want and located anywhere on the disk.
-
-User Provider
--------------
-
-When the authentication is successful, your driver must return an object that represents the user.
-This object must implement the interface `Kanboard\Core\User\UserProviderInterface`.
-
