OK, I ran 'dsconfigad -show' and got the following results. They basically look OK to my limited
understanding except for the Mapping options. I did check those mapping boxes, but I guess it
also wanted me to fill in actual values. I'll have to do a bit of research as I've no idea what
these values should be, nor do I know what happens if I leave the mappings un-checked as it
says it will then use "dynamically generated information for macOS" (whatever that means).

If any of these other settings look obviously suspect, please advise.

What is that?

I do have that checked, and it allows "All network users."

That's bad.

That's bad too! That's kind of the point of AD authentication -- not having to keep lots of
separate passwords all over.

That's not a problem. If thd AD/DC is down there are other problem. Windows users do get a
local copy of their desktop to work with, which is nice, but the AD/DC is also the only DNS, so
users could not get to the Internet. With Linux domain members, there really isn't an option to
have a local desktop copy (although, I could create a script to "fake" it), but it's pretty
easy to NFS mount the user's home directory, which is then available to that domain user when
he/she logs on per the AD configuration.

Not sure what that means (I'm a real Mac newbie). When you say "local homes", does that mean
the home directory is stored on the workstation, only? No redirection? How does a "Mobile User"
differ from any other kind of user?

I'll look at the nomad stuff, but this Mac needs to work in an existing Active Directory
system. I'll also look at the MacEnterprise maillist.

Meanwhile, do you have any idea on what should go in the Mapping Options? "Mapping UID to
attribute", what attribute? the UID of a specific domain user? That doesn't make sense. What is
"dynamically generated mapping info"? I'll try doing some research on this. I have a feeling
that these mapping options may be a big part of my problem.
