Description
I think I saw somewhere that there's a setting for automatically logging off users, but I can't find it now. We need to set this, especially for "admin". My concern is just with regard to stolen laptops, etc. I think that a very delayed time out, like 4 hours (or even anything less than 12 hours), is acceptable.
