I am attempting to configure Portal for ArcGIS so users can access it via ArcGIS for Desktop.
I follow the instructions as documented in Use ArcGIS Desktop with your portal, however when I click 'Connect' within the ArcGIS Administrator as shown below...
...I am presented with this Security Alert.
If I click 'Yes' and continue, I am presented with the same message again. If I click 'Yes' again and then 'Save', all seems well...
...Then when I fire up ArcMap and click 'File', I am not presented with an automatic 'Sign In' nor a connection to my ArcGIS Portal, despite apparently having Integrated Windows Authentication (IWA) set up successfully.
So I am unsuccessful in connecting to my Portal via ArcGIS Desktop in this particular environment. In another environment I have had success connecting to my Portal, and the only difference I noticed between the two approaches was that in the scenario above I am presented with the Security Alert regarding certificates and server authentication, whereas in the successful connection I was not.
Is this a certificate issue? How do I resolve it?
