One of our clients is using Portal for ArcgIS 10.3 in Windows Server 2012.
He builds a WebMap that points to a service in ArcGIS Server. The service is opened to everybody.
Upon trying to open the WebMap, it asks for user & password (see attached picture. It is written i Hebrew to register).
When I defined the ArcGIS Server as federated, the problem was solved but it is not a reason to define federation.
It happened to another colleauge of mine and she solved it the same way I did (with federate ArcGIS Server).
Is there any other solution?
Thanks a lot,
What release of ArcGIS Server is the web service from? And what authentication/security model is set for the Server site? Are these parameters the same for your colleague as well?
Hope this finds you well,
