I posted this question in another forum but got no replies so far, and have emailed Drupal but they said that I should post it here. Please help!

Which module(s) do I need to install, if I want to restrict individual pages, stories, or forums to specific groups of users? For example, I have 3 groups of user (A, B, and C), and I'd like forum A, page A and story A to be accessible only by group A; forum B, page B and story B to be accessible only by group B etc. And none of these able to be accessed by anon users (i.e. the public).

I know of Simple Access, but my host said that they have problem with it. They are willing to install other modules that will do what I need but unsupported. Which are the other modules I will need for the functionality above?

Please help!

Thanks, Petre.
