This is useful to enable the local system administrator to choose how applications authenticate users. Package Information Download (HTTP): Download (FTP): Download MD5 sum: &linux-pam-md5sum; Download size: &linux-pam-size; Estimated disk space required: &linux-pam-buildsize; Estimated build time: &linux-pam-time; Additional Downloads Optional documentation: Required patch: Linux-PAM Dependencies Recommended Optional sgmltools-lite and (for pam_userdb module) Install Linux-PAM by running the following commands: sed -i 's|DICT_DIR_CANDIDATES="|&/lib /lib/cracklib |' \ configure && patch -Np1 -i ../Linux-PAM-&linux-pam-version;-gcc4-1.patch && ./configure --enable-static-libpam --with-mailspool=/var/mail \ --enable-read-both-confs --sysconfdir=/etc \ --mandir=/usr/share/man && make If you downloaded the documentation and wish to install it, unpack the tarball into the doc directory: tar -xf ../Linux-PAM-&linux-pam-version;-docs.tar.bz2 -C doc Now, as the root user: make install && mv -v /lib/libpam.a /lib/libpam_misc.a /lib/libpamc.a /usr/lib && rm -v /lib/libpam{,c,_misc}.so && ln -v -sf ../../lib/libpam.so.&linux-pam-version; /usr/lib/libpam.so && ln -v -sf ../../lib/libpam_misc.so.&linux-pam-version; /usr/lib/libpam_misc.so && ln -v -sf ../../lib/libpamc.so.&linux-pam-version; /usr/lib/libpamc.so Install the documentation using the following commands: install -v -d -m755 /usr/share/doc/Linux-PAM-&linux-pam-version; && for DOCTYPE in html ps specs txts do cp -v -R doc/$DOCTYPE /usr/share/doc/Linux-PAM-&linux-pam-version; done sed -i 's|DICT_DIR_CANDIDATES="|&/lib /lib/cracklib |' configure: This command changes where configure looks to find the CrackLib dictionary. --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 -v /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 guidelines. rm -v /lib/libpam{,c,_misc}.so; ln -v -sf ... /usr/lib/...: These commands move the .so symlinks from /lib to /usr/lib. /etc/security/* and /etc/pam.d/* or /etc/pam.conf /etc/security/* /etc/pam.d/* /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. You should now reinstall the package.
