Details - Linux-PAM (Pluggable Authentication Modules)
Basically, it is a flexible mechanism for authenticating users.
Since the beginnings of UNIX, authenticating a user has been accomplished via the user entering a password and the system checking if the entered password corresponds to the encrypted official password that is stored in /etc/passwd . The idea being that the user *is* really that user if and only if they can correctly enter their secret password.
That was in the beginning. Since then, a number of new ways of authenticating users have become popular. Including more complicated replacements for the /etc/passwd file, and hardware devices Smart cards etc..
The problem is that each time a new authentication scheme is developed, it requires all the necessary programs (login, ftpd etc...) to be rewritten to support it.
PAM provides a way to develop programs that are independent of authentication scheme. These programs need "authentication modules" to be attatched to them at run-time in order to work. Which authentication module is to be attatched is dependent upon the local system setup and is at the discretion of the local system administrator.
