The Pluggable Authentication Modules (PAM) feature is an
authentication mechanism that allows you to configure how
applications use authentication to verify the identity of a user.
The PAM configuration files, which are located in the
/etc/pam.d
directory, describe the
authentication procedure for an application. The name of each
configuration file is the same as, or is similar to, the name of
the application for which the module provides authentication. For
example, the configuration files for passwd and
sudo are named passwd
and
sudo
.
