Note: This primarily concerns referenced map image layers & imagery layers.
With distributed collaboration, you can extend the reach of your GIS content by seamlessly sharing maps, apps, layers, and more with other organizations
(emphasis added)
I have successfully created a distributed collaboration between our ArcGIS Online organization and our ArcGIS Enterprise site. If I share layers to the workspace they appear in AGO just fine but when attempting to access the services, I'm prompted to log into our Enterprise site.
Doesn't this defeat the purpose of a collaboration? Why wouldn't I just manually add content to AGO from URLs from our Enterprise site and just embed/store the credentials in the item?
