I'm sorry, I didn't find a chapter in the IDM guide, but I found:
https://www.freeipa.org/page/V3/Serving_legacy_clients_for_trusts
which has some examples.

Appreciate the replies to even a non-IPA usage question. This list has a 
tremendous signal:noise ratio.


The info above sounds promising but I don't quite understand it. Is 
there a chapter in the IDM Admin Guide you can point me to to read up on 
or some other reference I can check out? Thanks!

What Jakub pointed out would be the way which currently would work.
Defining the ID ranges in sssd.conf in a completely flexible way is
currently not possible. There is https://pagure.io/SSSD/sssd/issue/2651
which tracks this feature although the title might be a bit misleading.

Sumit

So is the requirement absolutely to have the machines enrolled as part
of the AD domain?

If not, have you considered pointing the clients towards the compat tree
and using a plain LDAP setup, if your vendor supports that?
