Correct, that's why I'm on the case. My predecessors stopped updating it
due to compatibility issues. I'm just trying to find a way forward.

Yea, I believe that is the point of what I'm trying to do.

I'm just trying to find a way to make Samba4 be useful in some way and so
far I can find no place for it, let alone any use of it.

Thanks, if Samba worked like it used to perhaps one wouldn't have to think
so far out of the box and we could just get things done?

No, I really have no problem with that. It would be perfectly fine to
upgrade if Samba4 was as flexible as Samba3. There's nothing legacy in this
network except for Samba. We're being held back because of the Samba.
The problem is that there is no apparent upgrade path for the old system.
The corner stone of this deployment is that there's an existing centralized
authentication server however; Samba4 seems wants a paradigm shift so that
it becomes the princess of its own castle. It seems to me that it has
become the very thing that birthed its creation, a monster that wants to
strand its user base into its own proprietary system. All I trying to do is
to make Windows play nice with an existing open source authentication
server but all I'm hearing from the Samba project are vain, and to be quite
frank very condescending tones about switching all authentication to its AD
server. In my opinion the Samba project has devolved since I've last had to
work with it and it has become inflexible and passé. I do not think that
there will be a place for Samba if Microsoft continues to extend it's
offering to open source community. I didn't want to believe my compatriots
about the Samba4 issue. I feel like the terrorists have already won.
I really do appreciate that you took your time to reply but everything you
have said has been vapid, the mantra of a dead rhetoric. Thank you for at
least trying. Have a great day.
