Restrict access to user or group

[pavants]

I enabled the require user assignment and restricted access to some users, works well with authorized users.
Not authorized users receive the "internal server error" page

this is the server log:

Hi Pavants,
Thanks for the detailed report. We will be adding functionality for filtering by security group, by application roles, and/or user assignment in another chapter as a more advanced scenario.

We would also likely benefit from surfacing AAD error better in the UI!

Regards,
Sam
