I have users working on client machines who access our internal Portal through a web proxy. The IE browser experience is not single sign-on, but the browser does prompt for proxy authentication which passes through and signs the user into Portal. Is there a mechanism to set these settings in ArcGIS Pro? We can see that the Pro session is hitting the proxy, despite no underlying reference to it in the application, so it clearly is picking up on WinINet settings. FYI, we cannot replicate this behaviour with ArcGIS Desktop due to the connections proxy configuration capability in ArcCatalog.
