Hello! Thanks for downloading Linux-PAM. NOTES: How to use it is as follows: ./configure --help | less ./configure make Note, if you are worried - don't even think about doing the next line (most Linux distributions already support PAM out of the box, so if something goes wrong with installing the code from this version your box may stop working..) make install That said, please report problems to the bug reporting database on sourceforge.net. If you do not wish to make the modules dynamically loadable, but build a static libpam including all PAM modules, you have to call: ./configure --enable-static-modules In this case you cannot use pam_unix in the PAM config files instead you have to use pam_unix_acct, pam_unix_auth, pam_unix_passwd and pam_unix_session. To regenerate manual pages from the XML source files you need the docbook-xsl stylesheets in version 1.69.1 or newer, older versions had a bug which generates a broken layout.
