Hello Cephers! We know there is ongoing work that implements a certain subset of AWS Security Token Service for RGW endpoints and were curious to know if it'd include the ability to apply bucket-wide constraints as follows: { "Version":"2012-10-17", "Statement":[ { "Sid":"AddCannedAcl", "Effect":"Allow", "Principal": {"AWS": ["arn:aws:iam::111122223333:root","arn:aws:iam::444455556666:root"]}, "Action":["s3:PutObject","s3:PutObjectAcl"], "Resource":["arn:aws:s3:::examplebucket/*"], } ] } In lieu of such facility, presently the only way to update permissions of all objects within a bucket is to apply those permissions on each object individually, which isn't always practical. It'd be quite helpful to have this feature in Luminous, if possible! Thanks!
