Thanks for sticking with me on this.

I have this set up with pdns-recusor. Pdns-recursor then forwards to
the pdns auth server.
With this setup I can dig forward and reverse and get the prescribed
results for freeipa, but it's probably an illusion.
It's a fair comment to take it one step at a time, and I thought I had
made it past some :).
So if possible can you suggest the pieces of info I can supply to
confirm my progress.
Just for fun:
On the path I am now (which admittedly is ahead of myself) I can see
ipa-client install logs that are indicating that I do need to create a
subdomain zone by itself on the auth server; the installer does a dig
SOA test and it does not get the right domain back because I did not
separate the records into a new zone - I think ....
I did also create an 1.168.192.in-addr.arpa forward on the recursor,
and it forced me to use 1.168.192 probably because I am using
essentially random ip addresses. But, here for sure I am ahead of
myself. This forward however allowed me to successfully do dig -x on
various servers, like google, my own auth server etc.
OK, now I am stepping back .....  :) .....
