I've installed Fedora/RedHat DS a bunch of times. The basic configuration is quite painless. These are the docs I use: https://sites.google.com/site/disciplinux/linux/centralized-authentication Those worked as of CentOS 5.3, which was the last time I did it from scratch. For the OP, it might not be exactly sufficient since there was a requirement for minute by minute login allow/disallow, but I would not want to administer more than a handful of nodes without LDAP.
