UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/57.0.2987.133 Safari/537.36

Steps to reproduce the problem:
1. User misplaces or loses managed Chrome device
2. Unauthorized somebody finds it and disables Wifi or does not connect to a network
3. Unauthorized user is able to continue using the device indefinitely

What is the expected behavior?
There should be an option to have a device automatically disable itself if it is not able to fetch a policy update in x days. Similar to "inactive device reporting" in the CPanel.

What went wrong?
It is not possible to lock a device if it does not connect to a network and fetch a policy update

Did this work before? N/A

I understand that enforcing a screen lock would seem to achieve the same result of making the device unusable for the unauthorized user, however in our case, the devices are configured with public sessions that make the devices usable to any user.
