Title:
  Downward migration from separate domain name spaces can cause name
  clashes

Status in OpenStack Identity (Keystone):
  Won't Fix

Bug description:
  Now that domain have separate name spaces for user, group and project
  names (see: https://review.openstack.org/#/c/21951/), a problem exists
  if a customer tries to downgrade a populated database that makes use
  of this feature back to Folsom where there is a single global
  namespace.

  A possible solution would be to rename the names to something like
  "domain_name:user_name", but of course there is no guarantee that this
  will fit in the size of field available.  A second alternative would
  be to ONLY migrate back those entities that are owned by the default
  domain (since that is where they were put during the upward
  migration).

  Alternatively, we may just chose not to support such a downward
  migration once the domain features have been utilised.
