[Samba] Windows 7 v. Samba: why is default network profile in 'NETLOGON/Default User.v2' not used?

Setup:

- Samba 3.5.6 (Debian Stable release, amd64);

- Testing Windows 7 client behaviour, specifically with regard to users
  who don't yet have profiles.

The Windows docs state that a domain logon for a new user will cause the
default network profile to be used if available, if not then a default
local profile is used instead.  The location for the default network
profile is NETLOGON/Default User.v2 and I have content in that location.

However, a domain logon for a new user does not pick up the default
network profile, it falls through to the default local profile, which is
not what I want.

If I increase log level to 3 for Samba, I see this relating to the
default network profile location:

--------------------------------------------------------------------------------------

This reads as if some attempt is being made to look at 'Default User.v2'
and then 'Default User.v2/NTUSER.DAT', but I don't really understand
what's happening.

I'm happy server-side permissions are correct here and that does not
appear to be the root of the problem.

Can anyone help explain what's going on and what might be required to
fix?  Happy to post further logs if required, too.

Previous poster/thread at
http://lists.samba.org/archive/samba/2010-December/159897.html resulted
in a suggestion to set 'guest ok = yes' and 'browseable = yes'
on the
NETLOGON share, but this didn't make any difference in my case: same
messages in the logs etc.

Cheers,

Dave.

No-one has replied to my thread, so perhaps this is an ususual issue.
To help to debug it myself, can someone explain what Samba is 'doing'
during the above log section?  It looks to be Doing Something with
'Default User.v2/NTUSER.DAT', but it's not a file open or read,
because
I know what those look like in the logs.  What is
'call_trans2qfilepathinfo'?

All help appreciated,

Thanks,

Dave.
