[Samba] External Authentication

[Vex Mage]

Even if I am still thinking in the past it doesn't invalidate the problem I
came here to get guidance on. Instead I just get talked down to by some or
others don't even read the situation I'm trying to solve.

I don't need it to work like it used to in the NT4 sense. I don't need to
use NT4 protocols. I'm just in need of not having Samba4 write in all of
its documentation that forklift replacing your central authentication
server is the only way to move forward. Wasn't the design goal to make it
compatible in a Unix environment in the first place?

How am I holding back Samba? I have a central LDAP server I have no control
over but yet Samba4 requires me to replace it. I can see how most of
Samba's niche markets can do that but we can't.

AD is absolutely fine. Most of the other schools on our campus have moved
away from Samba to Windows AD or decided to drop authentication altogether
because it was easier to do so. Honestly, I don't think you're not
listening.
