After upgrading to version 21.0.5, the "Enable Autologin" feature on the login page no longer functions, and users are prompted for credentials every time they log in.
However, in v21.0.5, after being authenticated, the user has been prompted to the AWI login page and after pressing 'next', the user is taken to the dashboard.
Release : 21.0.5
Known Defect.
