That was my next question. I wanted to know if local.users did not work at
all fro FC5. Now I have your answer.

yes, you were talking about it two weeks ago. But I did not know that
there are things that do not work in the old way anymore.

I was wondering if there is a place (a guide or a book) where I can find
updated information. I am learning and it is kind of frustating to try to
set up policies and then realize that the main problem is that one is
working based on old instructions, and those are not always valid
(although some of them are valid some times). When I look for info in
internet most of the time I find instructions related to the old ways to
work with selinux.

Thank a lot,
Sandra
