PAM for Debian -------------- PAM (Pluggable Authentication Modules) provides system administrators with a powerful method of controlling system access and methods of authentication. The documentation for PAM is packaged in the "libpam-doc" package. The "Linux-PAM System Administrator's Guide" covers configuring PAM, what modules are available etc. The documentation also includes "The Linux-PAM Application Developers' Guide" and "The Linux-PAM Module Writers' Guide". The Debian default configuration is to emulate the old UNIX authentication.
