Translations:PAM/12/en

The final principle, which is part of the PAM name, is its pluggable architecture. When new back-ends need to be integrated, all the administrator has to do is to install the library for this back-end (by placing it in the right directory on the system) and configure this module (most of the modules use a single configuration file). From that point onward, the module is usable for applications. Administrators can configure the authentication to use this back-end and usually just need to restart the application.
