I have two questions:
1. How can the default DNS grants be restored, or fixed, without
knowing what they were?
2. Where can I get information about grants? I can't seem to find where
I was trying to get DDNS updates to work from DHCP server, and the
documentation doesn't mention executing 'ipa dnszone-mod example.com
--update-policy="grant rndc-key wildcard * ANY;"' will overwrite the
current grants breaking the DNS portion of ipa-client-install.

* FreeIPA 4.4.4 from Fedora repos
* ISC DHCP server 4.3.5 from Fedora repos
