OpenStack services return 401 Unauthorized after a redeployment which was launched from the wrong directory

Issue

Deployments with openstack overcloud deploy need to be launched from the same directory all of the time. If they are launched from the wrong Directory, it is possible to recover the installation, but service passwords for all services will be reconfigured by OpenStack Director.

Keystone seems to be running correctly.

All other services such as nova return 401 unauthrorized.
