OTOH https://github.com/openstack/barbican/blob/d2ce5952ddaa6fd659b0dcc0a0f8f0eba6f3988c/barbican/plugin/dogtag.py#L588 it is checked that mode is added into metadata only if it is not None. So will need to debug this a bit more on the barbican side.
This is happening on pike setup BTW, but did not see much difference in code with master.
