Windows Authentication rollbased

Product: PowerShell Universal
Version: 5.6.8

Hello everyone,

I need your help regarding authentication. I have noticed that when end users log out of the portal (Windows Auth), after logging in again, they are routed to the admin portal. I would like to prevent this. We use role-based AD groups to control this. Is there anything specific that needs to be configured in the authentication.ps1? For example, only users in the adminstrative role should see the admin portal, others just portal.
