/user

This is related to the issue. I assume it was signed as /admin/user,
but here we just use /user because that what's passed in the URI. Are
you accessing the gateway through virtual dns bucket name (e.g.,
admin.your-domain.com)?

This what our request header looks like.  ‘admin’ is the admin bucket.  The request doesn’t appear to be signed as /admin/user.  I wonder if the ordering of our header fields are incorrect insofar as they don’t match the canonical ordering expected by radosgw/S3 resulting in the digests not matching?
