I tried with this one
http://jondavidjohn.com/blog/2011/01/sca...r-ion_auth

but it's not working anymore and github contains only basic stuff without extended controller etc.
Also tutorial is a little mess, it contains Admin_Controller where it's saying "create MY_Controller.php" etc.

Does anyone have working version of how to protected pages or load user informations into object $the_user which would contain all user information with GROUP included? Because I couldn't find none.

I really don't like to copy/paste 10 lines of code to each controller.
