Ok, I call bullshit. I want you to show me one example of a FOSS implementation that lets you convert to Active Directory after the fact.

Amen. Amen. AMEN. Amen. I was reading through this thread wondering why in the HECK someone would want to subject themselves to this level of pain. Fact of the matter is, none of the "directory replacements" are even going to begin to touch on the level of quality, support, integration, and ease of use that you'd find with a 2003/2008 Active Directory implementation.

I mean, really, don't do it.
