Yes, I'm still hoping some day someone will make a Linux Distro that uses OpenLDAP for configuration as much as possible instead of flat files scattered all over the system, all with different syntax.
Over the last few weeks I've been setting up a personal linux server. Every single process I add has a different configuration. Systems like Postfix have nice things like "this combination of variable settings produces this behavior, but if you change one yes to a no you get something totally different".
