Ceph: PUTs requests to an RGW with pre-signed URLs (CORS) fail (403 response) after upgrading to RHCS 7.x.

Issue

PUTs requests to an RGW with pre-signed URLs (CORS) fail (403 response) after upgrading to RHCS 7.x.

After upgrading to 17.2.7 we have some users complaining that they can no longer do PUTs with pre-signed URLs. They are receiving messages like "Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource."

Command with a pre-signed URL will fail with a 403 response:
