[ceph-users] Rados example: create namespace, user for this namespace, read and write objects with created namespace and user

Hi, I'm trying to create a namespace in rados, create a user that has access to this created namespace and with rados command line utility read and write objects in this created namespace using the created user. I can't find an example on how to do it. Can someone point me to such example or show me how to do it? Regards, Rodrigo Severo
