Problem:
I’d like to regenerate the certificates of my puppet server (and I guess my clients?), because I need a cert that complies to RFC 2818 ([SERVER-2338] - Jira). Missing this causes errors once the certs are being used by GOLANG (Go 1.15 Release Notes - The Go Programming Language) which is the case e.g. for https://forge.puppet.com/modules/sensu/sensu. This module makes use of the puppet certs:
By default this module will configure the backend to use Puppet’s SSL certificate and CA.
In Foreman :: Manual I do not find a hint on how to regenerate the cert as the problem should be solved in puppet server 6.15.3 (Issue navigator - Jira).
