We have several laptops and many more users. On a field job there will be one person with a laptop set up to his domain account. The other people will have to use that laptop if they require access to a computer.
Since the computer is offline there is no way to authenticate the users password. (But since this information is cached when (one) user logs in while online, there must be a way to force this for 100 users too. That would be a smooth solution!)
How would you solve this scenario? We are talking of 100 users and about 35 laptops.
