title: AWS permissions required for sync
body: <p>I have a windows machine that need to sync a folder with S3.</p>
  
  <p>I try </p>
  
  <pre><code>"C:\Program Files\amazon\AWSCLI\aws.exe" s3 sync components 
  s3://test/MyTest/ --acl public-read --
  cache-control "public, must-revalidate, proxy-revalidate, max-age=1800"
  </code></pre>
  
  <p>got error <em>"A client error (AccessDenied) occurred when calling the PutObject operation: Access Denied"</em></p>
  
  <p><strong>s3 rm</strong> and <strong>s3 cp</strong> for the same directory works fine.</p>
  
  <p>I have the following permissions :</p>
  
  <pre><code>"Sid": "VisualEditor4",
              "Effect": "Allow",
              "Action": [
                  "s3:PutObject",
                  "s3:PutObjectAcl"
              ],
              "Resource":  
  </code></pre>
