We have asituation in our new environment:
1. We have ArcGIS Server10.3.1 in a Domain.
2. We are setting up ArcGIS Portal 10.3.1 on a DMZ location. As per security they will not add the portal machine to the domain, so It remains workgroup.
3. Server and Portal can communicate with each other, all ports are opened.I can access ArcGIS server Manager on Portal machine.
a) Can we federate Server with Portal?
b) Portal need to be authenticated with Active Directory. Is it doable?
Thanks in advance
