Newbie question re: authenticating users

[Jeffrey Davis]

I have successfully installed INN on my Linux RedHat 7.1 server and have
been able to connect to the news server remotely and post a test message.

My next task is to restrict access based on local user accounts (this news
server will only be used as an internal collaboration tool for our small
company).

I understand that I need to edit the readers.conf file... Here is what I
have so far:

access "All" {
    users: "*"
    newsgroups: "*"
}

auth "Users" {
    hosts: "*"
    default: "*"

}

I realize that this is a COMPLETELY open system... But I want to allow our
users to connect from any host and therefore secure access using their Unix
username and passwords.

Any help is greatly appreciated!
