permissions -- cleanest way to show certain pages to only certain users

[eluser]cruzanmo[/eluser]
Hi, there are certain pages that I don't want accessible to users based on their role. I assume doing this in the controller makes the most sense. Anyone tackled the problem of user permissions already and have advice on the best way to do it?

Thanks!

i think this depends very strong on how complex you like your permission system to be.

i have written a rather complex authentification and acl system.

therefore i added an additional controller which extends the ci controller, in this controller from which all other controllers are extended i can ensure that the current user is still logged in.

all other permission checking is done either in the controller constructor or directly in the controllers' methods
