I am trying to federate my ArcGIS Server with Portal but when I log in as administrator using the web adaptor, the Edit Settings link is disabled in the "My Organization" page. If I do not access the page using the web adaptor, the link is enabled. I click on Servers->Add Server and it complains that "Federation of servers is disabled when accessing the portal without using the web adaptor". Can someone please shed some light on what it is I'm doing wrong. Initially I thought maybe it had to do with not using signed certificates from a certificate authority so I requested a signed certificate and installed it on my web adaptor, portal and server but the issues remains. Has anyone ever experienced this? Thanks.
