Prompt all users to enter AD credentials when accessing PBIRS reports

Yes, kiosk PCs are a slightly different use case. If you want EVERYONE that connects to PBIRS to be prompted then you could switch from using Windows auth to using Basic auth (see https://docs.microsoft.com/en-us/sql/reporting-services/security/configure-basic-authentication-on-the-report-server?view=sql-server-ver15 ) Note: you should make sure you have HTTPS configured when using basic auth as the credentials are sent in clear text as part of the request.

The only issue then is that there is no "logout" button in the report portal, so the only way to "logout" is to close ALL browser windows. Closing just the current tab is not enough.
