Do ArcGIS Server licensing roles require configuring separate Web Adaptors?

Answer

Esri recommends configuring separate Web Adaptors for every ArcGIS Server licensing role via ArcGIS Web Adaptor. The best practice is configuring a Web Adaptor for Portal for ArcGIS, ArcGIS Server, and each ArcGIS Server licensing role.

The licensing roles operate as additional ArcGIS Server sites federated to Portal for ArcGIS and are usually accessed using the configured port number. Configuring the ArcGIS Server licensing roles with the Web Adaptor allows accessing the sites securely without exposing the port number within the URL.
