Server: Mounting a Minio S3 bucket in External Storages fails

Created on 31 Jan 2018 · 2Comments · Source: nextcloud/server

Steps to reproduce

Attempt to add a Minio S3 bucket in External Storages.

Expected behaviour

Nextcloud should mount the Minio S3 bucket.

Actual behaviour

Mounting fails when Nextcloud tries to read the bucket ACL.
It looks like this is because Minio doesn't use S3 ACLs.
Could inheriting ACLs be made optional?
