--- features: - | Added settings OPENSTACK_KEYSTONE_DOMAIN_DROPDOWN (boolean) and OPENSTACK_KEYSTONE_DOMAIN_CHOICES (tuple of tuples) to support a dropdown list of keystone domains to choose from at login. This should NOT be enabled for public clouds, as advertising enabled domains to unauthenticated users irresponsibly exposes private information. This is useful for private clouds that sit behind a corprate firewall and that have a small number of domains mapped to known corporate structures, such as an LDAP directory, Active Directory domains, geopgraphical regions or business units.
