Is the default behavior, of using MACHINE CREDENTIALS
for certain state control operations,  in place when NFS v4.0 is being used ?
or only if 4.1 or greater are being used ?

This is only for 4.1+.

Our NAS is v4.0 .... they will release their 4.1 soon

Ah see not sure why I didn't ask on the thread what nfs version it was
and right away jumped to talking about 4.1+. 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.
