My read only access user's of winbox can shutdown the system. Any idea to disable this option for read only user???
the default allowed actions for the user group "read" allow reboot.
change your read group Policies or create a new User group.
I agree the Default should not allow reboot. But it can be fixed easy enough.
Looking at your Pictures again you do have it disabled.
I tested on Version 3.11 the option is there and the box comes up but it does not allow it reboot or shutdown.
but did you see the other posts? you can't shutdown, even if it offers you to.
