PAM (pluggable authentication Modules) is a pluggable authentication module that is an efficient and flexible user-level authentication method that is commonly used by Linux servers today. Of course, in different versions of the Linux system to deploy PAM certification is different, this article will take the RHEL4 version as an example to resolve.1. The need to

When the number of users is relatively small, this method of user authentication is convenient, easy, maintenance work is also simple. However, when the number of users has tens of thousands of people, or even hundreds of thousands of, will spend a certain amount of time to find users, thereby reducing the efficiency of the server.
