Hello. Thank you for your email,
But the problem is that I use cephadm so it is not like a traditional way to configure, I am trying to test.

So if I remember correctly from when we did this a long while back, you don't really do much on the openstack deployment side.   Ceph comes with a swift compliant interface so the only thing required was in the ceph.conf to enable keystone as an authentication mechanism.
