I have started publishing data to our ArcGIS Enterprise (consisting of Server, Portal, and Data Store; the server is the federated/hosting server. I had a coworker test to see if they could access an item's data through the URL in the Content page. They were able to access it, but the top of the page indicated they were logged in as me, not themselves.
Does anyone know what can cause this? It concerns me that there is a security issue with the configuration of the ArcGIS Enterprise installation.
