I have some laptops that bind to AD using the built-in AD bind that work fine to start. After an unknown amount of time (days? weeks?), If i run an id username the connection to the domain is not found as i get a "no such user" response. Has anyone else seen this or know of a way to stop this from happening? It will become a huge issue when users are up to change their AD password and the computer is "disconnected" from the domain.
