making the home page require Auth (CakePHP)

Hello,

I just started to learn CakePHP and i'm trying to make the homepage (views\pages\home.ctp) only available to logged users, so if an unlogged users enter to the homepage they should be redirected to Users controller, where it prompts for user data, using Auth Component.

Where I can set the "controller" for the homepage? please correct me if i'm using the wrong terms :)

Thanks
