After review by the development team, it has been determined that this issue is related to a known limitation with the software that lies outside of Esri's control. The issue's Additional Information section may contain further explanation.
After publishing to a federated ArcGIS Server, the WMS can be unsecured. Alternatively, the Portal may be set to use Web Tier security, which is supported.
