How do I load a component inside a class that extends BaseAuthenticate in CakePHP?

I have created my own authenticator which handles OAuth 2:

class OauthAuthenticate extends BaseAuthenticate

I would like to use a custom component (extended from Component) in my OauthAuthenticate class.

How can I to load my component there? The traditional

public $components = array('OauthAuthenticate');

doesn't work - the component is not loaded.

BaseAuthenticate class cannot load component via $components array as is usual in controllers, but loading a component is possible in constructor:

private $utilComponent = null;

    public function __construct(ComponentCollection $collection, array $settings)
    {
        $this->utilComponent = $collection->load('Util');
    }
