Is there a way to prevent "User" from accessing the lab after a certain date?
We must keep assignments for a certain amount of time so we can't delete the labs immediately after the course ends. We are looking for a way to prevent the students from returning to their VMs and modifying their assignments.
I thought about changing the VM's password, but doing that one machine at a time is time-consuming. Is there any better way, or any way at all, to achieve this?
