Thanks!

Hello all,
We currently have Red Hat IDM implemented on our campus local network. It has a one-way
trust with our Active Directory and all of our Linux systems that live in our network use
IDM for auth/authz. We are looking to start deploying our linux images into AWS and want
to use our Red Hat IDM for auth control there as well and would like, if possible, to
remove any dependencies on our local network for systems that live in AWS in doing so.
With that being said, I would like to verify my understanding of how auth/authz works
with IDM and Active Directory. A client system will query a freeipa server in order to
get HBAC policies, sudo rules/commands, authorization for accounts to use certain
services, and user account/group information. The client system will authenticate the
user, whether for login or sudo/su, directly to Active Directory without going through the
freeipa server. Also, the freeipa servers will query AD for user account/group
information if it’s not already cached on the freeipa server. Is my understanding here
correct? If not, please enlighten me on where my misunderstanding is.
So, if my understanding as outlined above is correct, then to remove any depency on our
local network AD and FreeIPA/IDM for clients that live in AWS, we would need IDM servers
and Active Directory servers in AWS for the clients to use, correct? If that is the case,
is Azure Active Directory (AAD) a usable option in this case? Is there a way to specify
for clients to use the IDM servers and AD that are in AWS first, before attempting to use
the ones on our local network? Is there a way to specify for FreeIPA/IDM servers to use
the AD in AWS before attempting to use the ones on our local network?
I appreciate anyone who can verify or correct what I have above.
Thanks,
