Comment 4 for bug 1987644

The documentation only indicates that we should set `CloudDomain` and in principles `IdMDomain` should be derived from there.
https://docs.openstack.org/project-deploy-guide/tripleo-docs/latest/features/tls-everywhere.html#set-parameters

In either case, even when I included `IdMDomain` it did not get picked up. I added it as such:
```
parameter_defaults:
  CloudDomain: example.com
  IdMDomain: example.com
```

Are there other syntaxes to define parameters? Where can I see if a parameter is derived from another?

Ok starting to understand the Heat template structure a bit. The parameters are written in the same file and I need to provide a servers list as well. Let's see if that fixes it. It is unclear how not setting `IdMDomain` the `freeipa_ansible.client` can detect it. The documentation of the role says that it must be provided
