Ah. Let me describe it this way:
LAN with a mixture of Windows and Linux /workstations/ that doesn't
include a Windows /server/ to provide the AD resources (DNS, LDAP,
I guess it could be said that Samba4 acting as an AD DC might be the
proper choice here. But that sounds like some hassle without the
typical Windows GUI tools for administering AD. - I've also never done
that, so the unknown quantity is a bit deterrent.
I can also see having multiple Linux machines in a network without any
other OS. Possibly a cluster of Raspberry Pi Zeros on a Cluster Hat.
}:-) Use the underlying Pi as the gateway and infrastructure device,
including the directory.
The point being, there are environments with multiple Linux (Unix)
machines that don't have ready access to AD. Thus my asking about the
Unix (Linux) native method.

I feel like standing up AD, be it on Windows Server or Linux with
Samba4, is applying a Windows centric solution to Linux (Unix) systems.
I think this is acceptable if there is already Windows ~> AD in the mix.
But that's not always the case.
I also loath the idea that Unix (Linux) doesn't have a stand alone
central directory server solution. Or if LDAP + Kerveros is said
solution, so be it. - That's sort of what I'm trying to figure out.

I'm fairly certain that group policy objects do exist for Linux AD
clients. I think they are just simpler and can do far fewer things. I
think they also effectively map to the standard things that we could
already do in Linux. It's just behind a Microsoft MMC snap-in to edit GPOs.

I know a couple of people that have messed with PowerShell on Linux.
One of whom actually prefers PowerShell to Bash (et al) for scripting.
He stated that things are stored in data structures in PowerShell, and
as such were easier to manipulate and work with, compared to
unstructured data in STDIN / STDOUT.
He also stated that PowerShell was functionally just another shell for
doing things on Linux. In some ways, quite similar to moving between
/bin/sh, /bin/bash, /bin/zsh, etc. Obviously interacting with the shell
is different. But you're still calling Linux commands to do core
things. The glue is just different.

I was more meaning environments that don't include Windows Server, not
meaning to shun Windows.
Translation: What is the current Unix (Linux) method to provide central
user directory / authentication for about a dozen Unix (Linux / Solaris
/ *BSD / AIX) systems /without/ a Windows Server in the mix. I don't
own a license for any version of Windows Server that supports AD. Nor
do I feel compelled to buy one.
