We are migrating from Puppet to Ansible for configuration management, and I decided to create a playbook that will do all the things necessary to set up a DC and join the domain. I have found that in the domain joining process, an error stops replication from happening, and therefore stops the join. Replication to the currently joined servers is working fine, as reported by "samba-tool drs showrepl"

This did not cause me any grief at the time, but the object that is generating the errors is one of the calendar resources that I have created.
