Just a clarification: NIS+ and NIS are different things, and are conceptually
just about as different as Active Directory and NT4 domains. NIS+ has
facilities for heirarchical definition of users and administrative privilege,
where NIS is much more like the flat model in NT4 domain--without the ability to
add trusts.
If you're running a small set of machines where the users' passwords don't need
to change often, keeping /etc/passwd and /etc/shadow is reasonably workable.
You will have to ensure that your users only change passwords on the "main"
machine that contains the password file that you consider the master copy...
