Pluggable Authentication Modules

The Definitive Guide to PAM for Linux SysAdmins and C Developers

PAM-aware applications reduce the complexity of authentication. With PAM you can use the same user database for every login process. PAM also supports different authentication processes as required. Moreover, PAM is a well-defined API, and PAM-aware applications will not break if you change the underlying authentication configuration.

The PAM framework is widely used by most Linux distributions for authentication purposes. Originating from Solaris 2.6 ten years ago, PAM is used today by most proprietary and free UNIX operating systems including GNU/Linux, FreeBSD, and Solaris, following both the design concept and the practical details. PAM is thus a unifying technology for authentication mechanisms in UNIX
