If you grill people hard on "why do you need all that complex, expensive crap anyway?" you can switch them over to Google Apps, or Zimbra, or LibreOffice + Evolution + SLES and have all the same functionality. Share point? What does share point do that WebDAV + Samba + Apache + some kind of CMS + MediaWiki can't, besides requiring an expensive share point admin and lots of licensing fees?

LDAP and kerberos have Linux implementations, but throwing the *nix way of doing this out the window in favor of the AD route is a really silly idea unless you need to integrate with existing windows crap. Basically, Windows perpetuates itself, and the solution is to drop it entirely and across the board.

This betrays a lack of experience with a large organization. The "nix way" is every program having their own configuration file with its own syntax and needing a signal (or restart the process) to change said configuration. Directories are far superior for this and it isn't a "windows" thing. It was Novell who first got serious with directory services.

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.

LDAP is a PITA. Flat files usually have three things to remember:

# is a comment key value

That's the format of most config files I see.

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".
