Hi, I am a newbie to ceph. I have gone through the ceph docs, we are planning to use rgw for object storage. From the docs, what I have understood is that there are two types of users: 1) ceph storage user 2) radosgw user I am able to create user of both the types. But I am not able to understand how to restrict the rgw user access to a pool. My questions are below: 1) How to restrict the access of a rgw user to a particular pool ? Can this be done using placement groups ? 2) Is it possible to restrict rgw user access to a particular namespace in a pool ? 3) I can understand the flow till he is able to write to a bucket using the .index pool object. But I am not able to understand the flow how the rgw user can write objects in pool. Where can I check the permissions ? *Thanks & Regards,* *Vishwas *
