How do i implement content access control?

[AL-Kateb]

Hello everybody!

i am building a CMS that will be used for variant of websites (article directories, blogs, 5-page websites, software directories ... etc)

and i was wondering what is the best way to implement a content access control in a way that makes it flexible and easy and i can't find a proper logic for that.

for example an articles directory website will have categories and articles within those categories and the admin wants for instance to deny access to specific category or article based on user group, i cannot seem to figure out a proper logic for that, something that i can actually use with all the modules and does not require me to change every single "select" statement i have.

so what do you guys have to suggest about this.

thanks
