[Fedora-directory-users] Best way to populate DS with account and group!

[Alex aka Magobin <magobin gmail com>]

Hi, now that I have a Fedora DS installed and replicated correctly with
ssl encryption, I would to know what is the best way to populate DS with
accounts to authenticate linux clients; the goal is to automate accounts
creation for clients authentication and mail (postfix) authentication.
So, for example I want that when I make an account on DS for "test" it
must authenticate linux client and must authenticate postfix user (and
obviously user must to be added to postfix group)
What it the best way?

thanks in advance
Alex
