Help with realm IPA and host OTP

Hi All,

Apologies if this question has been asked before, but I can't find anything
definitive. I'm running Foreman 1.14.2 with Katello 3.3 with FreeIPA 4.4.
I've followed the realm integration instructions found
here: Foreman :: Manual without an
issue. The hosts I'm trying to add aren't managed by Foreman - most of our
hosts are spun up in OpenStack and we're then using Katello as a repo
server and FreeIPA as the IDM. My questions are:

  1. When we install the katello-agent, the host appears in Foreman - is
    there a way to automatically include the host in the realm we've configured?
  2. If I manually add a host into the realm, I see a host entry in FreeIPA,
    but it's not enrolled. The host OTP is indicated as set, but how do I get
    this OTP so that I can enroll the client?

Thanks for your time.
Cheers!
