AuthComponent is used to verify and manage a user's connection to your application. If you only have one type of user in your system, you only would need to use AuthComponent.

ACL is used to manage whether or not an authenticated user can access a given object/action in the system. ACL requires AuthComponent (or another verification and session management tool) to first verify who the user actually is. In other words, if you need ACL, you need AuthComponent too.
