=Pluggable Authentication Module (PAM) Project= Main Menu

Overview
Pluggable Authentication Module (PAM) is a flexible mechanism for authenticating users. Since the beginnings of UNIX there have been a variety of ways to authenticate users. Authenticating a user has been accomplished by entering a password and the system checking if the entered password corresponds to the encrypted password stored in the system.

PAM uses a pluggable, modular architecture, which affords the system administrator a great deal of flexibility in setting authentication policies for the system.


 * Advantages**
 * a common authentication scheme that can be used with a wide variety of applications.
 * significant flexibility and control over authentication for both system administrators and application developers.
 * a single, fully-documented library which allows developers to write programs without having to create their own authentication schemes.
