%general-entities; ]> The Linux-PAM package contains Pluggable Authentication Modules. This is useful to enable the local system administrator to choose how applications authenticate users. Download (HTTP): Download (FTP): Download size: &Linux_PAM-size; Estimated Disk space required: &Linux_PAM-buildsize; Estimated build time: &Linux_PAM-time; Required patch: Install Linux-PAM by running the following commands: patch -Np1 -i ../Linux-PAM-0.77-linkage-3.patch && autoconf && ./configure --enable-static-libpam --with-mailspool=/var/mail \ --enable-read-both-confs --sysconfdir=/etc && make && make install && mv /lib/libpam.a /lib/libpam_misc.a /lib/libpamc.a /usr/lib && ln -sf ../../lib/libpam.so.&Linux_PAM-version; /usr/lib/libpam.so && ln -sf ../../lib/libpam_misc.so.&Linux_PAM-version; /usr/lib/libpam_misc.so && ln -sf ../../lib/libpamc.so.&Linux_PAM-version; /usr/lib/libpamc.so autoconf: This is necessary as in the patch, we change where PAM looks for the cracklib libs. This requires that the configure script be recreated. --enable-static-libpam: This switch builds static PAM libraries as well as the dynamic libraries. --with-mailspool=/var/mail: This switch makes the mailspool directory FHS compliant. --enable-read-both-confs: This switch lets the local administrator choose which configuration file setup to use. mv /lib/libpam.a /lib/libpam_misc.a /lib/libpamc.a /usr/lib: This command moves the static libraries to /usr/lib to comply with FHS. /etc/pam.d or /etc/pam.conf Configuration information is placed in /etc/pam.d or /etc/pam.conf depending on user preference. Below are example files of each type: # Begin /etc/pam.d/other auth required pam_unix.so nullok account required pam_unix.so session required pam_unix.so password required pam_unix.so nullok # End /etc/pam.d/other # Begin /etc/pam.conf other auth required pam_unix.so nullok other account required pam_unix.so other session required pam_unix.so other password required pam_unix.so nullok # End /etc/pam.conf The PAM man page (man pam) provides a good starting point for descriptions of fields and allowable entries. The Linux-PAM guide for system administrators is recommended for further reading. Refer to for a list of various modules available. The Linux-PAM package contains unix-chkpwd and libpam libraries. No description available. libpam libraries provide the interfaces between applications and the modules included with PAM.
