At my work, we are primarily Linux-based, and try and to make our Windows and OS X clients behave in that world. Recently we've moved to storing all of our user, group, and automount data inside an OpenLDAP server. This works great for our Linux clients, but I found that there wasn't much step-by-step documentation for getting OS X clients configured to talk directly to a Linux OpenLDAP server.
So here's my documentation on how to set this up. Hopefully later this week, I'll also have posted the scripts we use to automatically sync our Linux automount configuration into our LDAP server in an OS X usable format.
