Open Stack

Hi Ignazio,

That's expected behavior with rados gateway. They follow S3's lead and
have a unified namespace for containers across all tenants. From their
documentation [0]:

    If a container with the same name already exists, and the user is
    the container owner then the operation will succeed. Otherwise the
    operation will fail.

FWIW, that's very much a Ceph-ism -- Swift proper allows each tenant
full and independent control over their namespace.
