Moved foreman-proxy to new host, no longer able to create DNS record updates

Support
1

I've migrated my DHCP server from CentOS 6.5 to RHEL 6.5. This host serves
as smarthost for DHCP and DNS.

Since the migration when I attempt to create a new host, the UI gives me an
error:

Create DNS record for test123.domainname.corp task failed with the
following error: ERF12-2357 [ProxyAPI::ProxyException]: Unable to set DNS
entry ([RestClient::BadRequest]: 400 Bad Request) for proxy
https://dhcp02.domainname.corp:8443/dns

My DNS is provided by AD. I have tested manually if the keytab file and
kerberos configuration are correct by running nsupdate -g sucessfully.

Wondering if maybe one of the gem packages from EPEL didn't install
properly or might have a bug.

Any help is appreciated.

Try removing "dns_key" from /etc/foreman-proxy/settings.yml, then
"service foreman-proxy restart".

We recommended setting this as a workaround for a bug in 1.5.0, but I
didn't realise when fixing it properly that the workaround would then
cause an error - apologies.

Yep, that was it.

Thanks for the quick response.
