[ceph-users] How to disable S3 ACL in radosgw

Hi, Is it possible to disable ACL in favor of bucket policy (on a bucket or globally)? The goal is to forbid users to use any bucket/object ACLs and only allow bucket policies. Seems there is no documentation in that regard which applies to Ceph RGW. Apology if I am sending this in the wrong mailing list. Regards, Rasool
