RHEL 8 and Apache and Kerberos

I'm trying to migrate one of our old hosts from RedHat 6 to RedHat 8. All working well so far and have httpd installed and basically running.

I started working on setting up the kerberos authentication as our old host and found that mod_auth_kerb is replaced with mod_auth_gssapi. The instructions I've found for setting up gssapi all say I need to have the ipa-client installed as well. The problem is that an ipa-client doesn't work in an Active Directory domain - you need an ipa-server somewhere from what I can tell.

So the question is, how do we install apache on RedHat 8 and allow for kerberos authentication without the need for an ipa-server and instead use the currently joined to domain controlled by Active Directory.
