Comment 5 for bug 912143

And the tenant problem is revealed:

mapper url is :

        mapper.connect("/users/{user_id}/OS-KSADM/tenant",
                    controller=user_controller,
                    action="update_user_tenant",
                    conditions=dict(method=["PUT"]))

while call is performed using

        return self._update("/users/%s/tenant" % base.getid(user),
                            params, "user")

An "OS-KSADM" is missing from URL.
