BUG
When using Amazon Web Services (AWS) and attempting to federate ArcGIS Server with Portal for ArcGIS, the federation process fails if the steps in the documentation are followed explicitly.
Step 20 in the documentation to Deploy Portal for ArcGIS on AWS states that Portal's system properties must be updated to reflect the public DNS name. This change causes the federation to fail. At this time, there is not clear documentation of what this setting does.
