Infoblox DNS provider have a single setting called dns_server which is used for two purposes:
- HTTP endpoint which is used to communicate with Infoblox
- DNS resover used to do conflict checks by common DNS code
It's very common to configure Infoblox in a way that the API node does not provide DNS resolver. Currently it's not possible to do such configuration and a manual hotfix is needed:
Nn dns_common.rb (find it on the filesystem) change this line:
@server = server || "localhost"
@server = "18.104.22.168"
where 22.214.171.124 is IP address of (preferably) authoritative DNS server from the Infoblox cluster, or a caching DNS server.
Created redmine issue https://projects.theforeman.org/issues/27046 from this bug
The solution is more complicated and it needs incompatible changes in the smart proxy core DNS API. Therefore this is a temporary solution to override DNS server to query during DNS add/remove operations.
Moving this bug to POST for triage into Satellite 6 since the upstream issue https://projects.theforeman.org/issues/27046 has been resolved.
So after discussion with Ewoud I worked on a proper fix - DNS conflict check does not use system resolver but Infoblox REST API now.
