I'm trying to run ovirt-dr generate but its failing:

/usr/share/ansible/collections/ansible_collections/redhat/rhv/roles/disaster_recovery/files/ovirt-dr generate
Log file: '/tmp/ovirt-dr-1649673243333.log'

 CA file: ./ca.pem
[Generate Mapping File] Failed to generate var file.

When I examine the log file:

My suspicion is that the script doesn't like third party certs.

Has anyone got this working with third party certs?  If so, what did you need to do?

Thanks
