Likewise Open-Sources Active Directory Authentication for Linux (eWeek)

Good stuff. :) I enjoy the clarifications.

I was thinking it terms of small business setups were you'd have some guy setup a office as
quick as possible then run away and leave somebody 'who knows computers' to handle the system
while that guy will occasionally show up to do support or do phone support. (Although I
definately got other stuff mixed up into what I saying.)

I know enterprise support for this stuff is pretty much all there. But what I think is needed
is a stupid-simple default setup for quick-n-dirty small-to-medium deployments of Linux
desktops in a mixed environment. 

Microsoft's approach with things like SBS is to 'get them while their young'. Get them using
things like AD and Exchange before they are IT-savy enough to realise that it may not be the
best choice. Then as these companies grow Microsoft can use their infamous lock-in to retain
these people as customers far beyond were it would make sense to go with a pure-microsoft
setup.
