I am trying to add another client in my main location and getting the following information:

I have checked my /etc/resolv.conf and made sure that they are pointed at the current local FreeIPA nameservers/resolvers.  

Here is the output /var/log/ipaclient-install.log

I did have a realm for stl1.example.net but removed that and the DNS zone.  I have other servers that are freeipa01.$location.exmaple.net that joined just fine.

Am I doing something wrong?
