Rafael, you can use the OpenStack CLI client to do all the actions. It is not affected by this issue in horizon. i.e. you can use "openstack user create --domain xxx --project-domain xxx etc" for the user, "openstack domain create ..." and "openstack project create ..." for the creation, and then the "openstack <thing> list" to show the user/domain/project list, and then "openstack <thing> show" to get more detail. Everything works as normal.
