With 4.0, operations such as open/close would be done with the user's credentials. If they expire, that's a problem. 4.1 protocol is preferred over 4.0 for variety of reason and thing could be one of them. I can confirm that the same experiment I've done with 4.1, with 4.0 leads to the client not sending an open to the server (since it has no creds to use). I don't believe there are any provisions in the 4.0 spec for allowing something like a CLOSE to be sent with something other than the principal's creds that created that state.
