Well, since one of my most popular all-time blog posts is Login system with CakePHP in under 10 minutes I think it's time that I update it to version 2.x (currently 2.2 at the time of writing). The original post was probably written for version 1.2 or 1.1 and there have been several changes made, especially with breaking changes to the AuthenicateComponent.
The beautiful part is the changes are extremely limited. In fact, only the UsersController requires a few minor changes.
