Introduction to PAM Library

The PAM Library package contains Pluggable Authentication Modules. This is useful for enabling the local system administrator to choose how applications authenticate users.

RedHat develops a set of external modules for use with Linux-PAM. This includes the pam_console module which can be used by some programs such as HAL and gnome-volume-manager. The purpose of pam_console is to indicate which user is active at the console and take appropriate actions. It does this by listing active users in the /var/run/console directory and assigning one to the console.lock file.

Dependencies

Optional

• Cracklib
• Prelude
• sgmltools-lite

Note

Autoconf-2.60 or greater is required to execute the following instructions. Build instructions for an acceptable version of Autoconf may be found in the development version of CLFS.

           --enable-docdir=/usr/share/doc/Linux-PAM-1.1.3 \
           --enable-read-both-confs &&
make

Install the package:

make install &&

Configuring pam_console

The altering of device permissions is unnecessary. In this case, only the console locking actions are needed. Replace one of the pam_console configuration files to achieve this.

cat > /etc/security/console.handlers << "EOF"
# Begin /etc/security/console.handlers
console consoledevs tty[0-9][0-9]* vc/[0-9][0-9]* :[0-9]\.[0-9] :[0-9]
EOF

Contents

Note:
The files that come with pam_console need to be added to this list.

Installed Libraries:	libpam.{so,a}, libpamc.{so,a}, libpam_misc.{so,a}
Installed Directories:	/etc/pam.d, /etc/security, /lib/security, /usr/include/security

Short Descriptions

pam_tally	is used to view or manipulate the faillog file.
libpam.{so,a}	provide the interfaces between applications and the PAM modules.
