The CA renewal master flag was uncoditionally set on every replica during replica install. This causes the Dogtag certificates initially shared among all replicas to differ after renewal. Do not set the CA renewal master flag in replica install anymore. On upgrade, remove the flag from all but one IPA masters. https://fedorahosted.org/freeipa/ticket/5902 Reviewed-By: Martin Babinsky <mbabinsk@redhat.com>
