.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
