How do you test Pam?

How to Check a Program is PAM-aware. To employ PAM, an application/program needs to be “PAM aware“; it needs to have been written and compiled specifically to use PAM. To find out if a program is “PAM-aware” or not, check if it has been compiled with the PAM library using the ldd command.

Notice that the login program, used by programs such as getty and in. telnetd to authenticate users and log them in, is linked against the PAM libraries. When a specific service such as login requires user authentication, it employs the PAM routines to complete this authentication.

What is PAM based authentication?

A pluggable authentication module (PAM) is a mechanism to integrate multiple low-level authentication schemes into a high-level application programming interface (API). PAM allows programs that rely on authentication to be written independently of the underlying authentication scheme.

How does Linux-PAM work?

Linux-PAM (short for Pluggable Authentication Modules which evolved from the Unix-PAM architecture) is a powerful suite of shared libraries used to dynamically authenticate a user to applications (or services) in a Linux system.

How PAM authentication works in Linux?

Linux-PAM separates the tasks of authentication into four independent management groups:

1. account modules check that the specified account is a valid authentication target under current conditions.
2. authentication modules verify the user’s identity, for example by requesting and checking a password or other secret.
