Comment 1 for bug 1782372

Ah, I can add some specificities of my deployment :
- Multi domain, with one backed by Active Directory
- Different internal and public endpoints, managed by haproxy
- openrc points to the Default domain admin account, with internal endpoints
- flat Netwok for external shared network
- VXLAN for private networks with Linux Bridges
- Ceph for glance/nova/cinder with erasure coding pools
