2.4.2.1. PAM Service Files
Each PAM-aware application or service has a file in the /etc/pam.d/
directory. Each file in this directory has the same name as the service to which it controls access.
The PAM-aware program is responsible for defining its service name and installing its own PAM configuration file in the /etc/pam.d/
directory. For example, the login
program defines its service name as login
and installs the /etc/pam.d/login
PAM configuration file.
