Hi,
Assuming that I've got a federated Enterprise setup and SAML authentication.
I was wondering why a user needs to authenticate again when accessing the ArcGIS Portal Directory when the user has already logged into Portal. Below is an example of what I meant by the above:
1. User logs into ArcGIS Portal
2. Accessing the ArcGIS REST Services does not trigger any authentication -- https://<URL>/arcgis/rest/services
3. When accessing the ArcGIS Portal Directory, it requires users to authenticate again -- https://<URL>arcgis/sharing/rest/
When a user has already logged into Portal, shouldn't ArcGIS Portal Directory know since it's pretty much the REST interface for Portal.
