Access denied on swiftstack cluster

[adiospeds]

I recently deployed a swiftstack cluster and am able to upload/download objects using aws cli. However when I try to benchmark the swiftstack cluster, I get following error.

The bucket gets created, but when s3-benchmark tries to make any upload request the screen gets flooded with above error.

The X-Amz-Date (https://github.com/wasabi-tech/s3-benchmark/blob/master/s3-benchmark.go#L196) format should be Wed, 01 Mar 2006 12:00:00 GMT. So change the time format to time.UnixDate` and it should work.

       //     dateHdr := time.Now().UTC().Format("20060102T150405Z")
       dateHdr := time.Now().UTC().Format(time.UnixDate)

I'll send a pull reuqest.

They buried docs for v2 signatures down in an appendix, but sure enough, AWS says

The value of the x-amz-date header must be in one of the RFC 2616 formats (http://www.ietf.org/rfc/rfc2616.txt).

so I'm inclined to agree that the format's wrong. I'm not sure time.UnixDate is right though; would time.RFC1123 be better?

Longer-term, it might be better to move to v4 signatures (which use the YYYYMMDD'T'HHMMSS'Z' format for x-amz-date.

@tipabu thx, agreed. The time.RFC1123 is better.

Thanks charz, this fixes the issue
