.SH NAME

system-auth \- Common configuration file for PAMified services

.SH SYNOPSIS

.B /etc/pam.d/password-auth

.B /etc/pam.d/fingerprint-auth

.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 substack

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

Previously these common configuration files were included with the help

of the

.BR include

directive. This limited the use of the different action types of modules.

With the use of

.BR substack

directive to include these common configuration files this limitation

no longer applies.

.SH BUGS
