title: Granting read access to the Authenticated Users group for a file
body: <p>How do I grant read access to the Authenticated Users group for a file? I'm using s3cmd and want to do it while uploading but I'm just focusing directly on changing the acl. What should I put in for <a href="http://acs.amazonaws.com/groups/global/AuthenticatedUsers" rel="noreferrer">http://acs.amazonaws.com/groups/global/AuthenticatedUsers</a>? I have tried every combination of AuthenticatedUsers possible.</p>
  <blockquote>
  <p>./s3cmd setacl
  --acl-grant=read:http://acs.amazonaws.com/groups/global/AuthenticatedUsers
  s3://BUCKET/FILE</p>
  <p>./s3cmd setacl
  --acl-grant=read:AuthenticatedUsers
  s3://BUCKET/FILE</p>
