Linux-PAM is a free implementation of the DCE-RFC 86.0
from Sunsoft. The main site of the Linux-PAM development
can be found on
www.kernel.org.
Basically, PAM is a flexible mechanism for
authenticating users.
PAM provides a way to develop programs that are
independent of authentication scheme. These programs
need "authentication modules" to be attatched to them at
run-time in order to work. Which authentication module
is to be attatched is dependent upon the local system
setup and is at the discretion
of the local system administrator.
