www.rpmfind.net is a great place to find RPMs. OpenLDAP 2.0.7 is at http://rpmfind.net/linux/rpm2html/search.php?query=openldap Be sure to download the appropriate RPM for your architecture. But if you already have the .tgz, the following list of commands should work. Are you getting a "library not found" error or somesuch? tar -xzvf openldap-2.0.7.tgz cd openldap-2.0.7 ./configure make depend make su [root password] make install
