I am creating a new install of Apigee OPDK 4.50.00. I have installed everything similar to how I did it with 4.19.01, which includes SSO/SAML. When I try to access the New UI, I get the proper prompt for SSO and I can login and see the home screen. However, before finishing the home screen load, a Basic auth prompt pops up trying to access my user's roles (probably to configure the UI to what I am entitled to). The SSO access token IS being placed on the call to get my user's roles so I am not sure why that is not working.
The documentation is not clear about the Shoehorn UI and if both shoehorn and new UI still use separate SSO client ids, etc.
