user administration issues in redhat linux

I need user administration related issues in redhat linux
plz tell me issues.Thanks in advance one who replied for my post

pardon? User issues? You want us to tell you what can go wrong with users?? How are we supposed to do that? We're here to help you fix actual issues.

In RHL or UNIX, most of the things revolve around one or more user, like acount creation, group, permissions, files or directories, quotas, login etc.

So just saying 'user administration' isn't enough. Let's know what do you want to admin?

Also you can also follow RHL guides like here or here.

please post what these unknown issues are ?
