The Redhat documentation that I am referring to is here:
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/...
I just noticed that the doc is for RH 8, while I am on RH 7. I don't know if that
would make any difference, but there is a difference in the version of FreeIPA. RedHat 7
is on 4.6, while Redhat 8 is on 4.8
