First let me say that I personally don't know AD at all, I'm doing this job
because I noted that those who should do it don't do it ;) And I rely on
it so I better do it myself.

What I know is that they use AD for things like Software updates and other
stuff. I don't know exactly what for but it seems not to be possible
without AD.

Sounds very interesting

that's an option too, the question is how much work would that be.

I simply didn't consider it yet because I didn't know that Samba is that

Thanks for the pointers, I will definitely do some more research on that.

BTW we will document what we are doing and publish that in the web as soon
as we reached the final state (will be late summer I guess). I will
announce that on this list as soon as it's done.
