In this case the connection (session setup) is over, as the utmp support
shows that the vuid has been invalidated, and the user logged out.  So
its probably not this.

Note that this is not a 'domain logon', its a normal file-share
connction, and the drive is successfuly un-mapped when the user hits the
'disconnect' button on our logon applet.

Note also that there are no errors being reported, just mysteriously
appering files.  What I am wondering is if somthing is keeping the
directory open, and if samba is then accidently pulling this out of the
'cache', and creating a new file in it.

All the home directories are mod 0700, as a matter of note.

Also, changing how this works is not an option - we have a fairly large
number of users, and this is how they expect it to work.  We have them
