message "You are not allowed to perform this action, please contact your system

Wiindows Client Upgrade 20.9 has introduced a new problem.

I have the Password Protection enabled and set but now I can no longer access anything unless I’m logged in as an administrator on the machine. If a non administrative user tries to access the UI or temporarily disable the shields… a dialog is shown with the message “You are not allowed to perform this action, please contact your system administrator.”.

What am I supposed to do with that? What is the point of the protection password? This worked on 20.8.

So this is apparently fixed in newer versions (~20.7 maybe?).
