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

Non-Multilib

If you would like to build the pam_console module run the following commands: 

tar -xf ../pam-redhat-0.99.5-1.tar.bz2 && 
sed -i 's,modules/Makefile,& modules/pam_console/Makefile,' configure.in && 
sed -i 's/SUBDIRS =/& pam_console/' modules/Makefile.am && 
sed -i '/^permsd_DATA/d' modules/pam_console/Makefile.am && 
autoreconf -v

Configure and compile the package: 

./configure --libdir=/usr/lib --sbindir=/lib/security \
           --enable-securedir=/lib/security \
           --enable-docdir=/usr/share/doc/Linux-PAM-1.1.3 \
           --enable-read-both-confs &&
make

Install the package: 

make install &&
chmod -v 4755 /lib/security/unix_chkpwd &&
mv -v /lib/security/pam_tally /sbin &&
mv -v /usr/lib/libpam*.so.0* /lib &&
LIBNAME=$(cat libpam/libpam.la | grep library_names | cut -f2 -d"'" | cut -f1 -d" ") &&
ln -sf ../../lib/$LIBNAME /usr/lib/libpam.so &&
LIBNAME=$(cat libpamc/libpamc.la | grep library_names | cut -f2 -d"'" | cut -f1 -d" ") &&
ln -sf ../../lib/$LIBNAME /usr/lib/libpamc.so &&
LIBNAME=$(cat libpam_misc/libpam_misc.la | grep library_names | cut -f2 -d"'" | cut -f1 -d" ") &&
ln -sf ../../lib/$LIBNAME /usr/lib/libpam_misc.so

sed -i 's/SUBDIRS =/& pam_console/' modules/Makefile.am && 
sed -i '/^permsd_DATA/d' modules/pam_console/Makefile.am && 
autoreconf -v

Configure and compile the package: 

CC="gcc ${BUILD32}" ./configure --libdir=/usr/lib --sbindir=/lib/security \
           --enable-securedir=/lib/security \
           --enable-docdir=/usr/share/doc/Linux-PAM-1.1.3 \
           --enable-read-both-confs &&

Install the package: 

make install &&
chmod -v 4755 /lib/security/unix_chkpwd &&
mv -v /lib/security/pam_tally /sbin &&
mv -v /usr/lib/libpam*.so.0* /lib &&

If you would like to build the pam_console module run the following commands:

sed -i 's/SUBDIRS =/& pam_console/' modules/Makefile.am && 
sed -i '/^permsd_DATA/d' modules/pam_console/Makefile.am &&

Configure and compile the package: 

CC="gcc ${BUILDN32}" ./configure --libdir=/usr/lib32 --sbindir=/lib32/security \
           --enable-securedir=/lib32/security \
           --enable-docdir=/usr/share/doc/Linux-PAM-1.1.3 \

ln -sf ../../lib64/$LIBNAME /usr/lib64/libpam_misc.so

Confuguring pam_console

You only need to view this section if you built the pam_console module.

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 Programs: pam_tally
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.
