.TH SYSTEM-AUTH 5 "2009 Apr 10" "Red Hat" "Linux-PAM Manual"
.SH NAME

system-auth \- Common configuration file for PAMified services

.SH SYNOPSIS
.B /etc/pam.d/system-auth
.B /etc/pam.d/password-auth
.B /etc/pam.d/fingerprint-auth
.B /etc/pam.d/smartcard-auth
.sp 2
.SH DESCRIPTION

The purpose of these configuration files are to provide a common
interface for all applications and service daemons calling into
the PAM library.

.sp
The
.BR system-auth
configuration file is included from nearly all individual service configuration
files with the help of the
.BR include
directive.

.sp
The
.BR password-auth
.BR fingerprint-auth
.BR smartcard-auth
configuration files are for applications which handle authentication from
different types of devices via simultaneously running individual conversations
instead of one aggregate conversation.

.SH NOTES
There should be no
.BR sufficient
modules in the
.BR session
part of
.BR system-auth
file because individual services may add session modules after
.BR include
of the
.BR system-auth
file. Execution of these modules would be skipped if there were sufficient
modules in
.BR system-auth
file.

.sp
Conversely there should not be any modules after
.BR include
directive in the individual service files in
.BR auth account
and
.BR password
sections otherwise they could be bypassed.

.SH BUGS
.sp 2
