[Freeipa-users] DNS update failing

[Jason Sherrill]

Hello,

I've recently implemented freeIPA in a mixed environment of Mac OS 10.12
and Windows 10 with limited issues!

One issue is that updating the reverse zone via nsupdate works without
issue, updating to the forward zone results in a REFUSED status. Below is
my zone config, named.conf, and an example of client-side behavior.  I'm
new to nearly all systems involved- misconfiguration is likely. Thanks!
