Linux-PAM is designed to provide the system administrator with a
great deal of flexibility in configuring the privilege granting
applications of their system. The local configuration of those aspects
of system security controlled by Linux-PAM
is contained in one of
two places: either the single system file, /etc/pam.conf
; or
the /etc/pam.d/
directory. In this section we discuss the
correct syntax of and generic options respected by entries to these
files.
