Puzzling local share permissions problem with ssh sessions on Win2K3

- Subject: Puzzling local share permissions problem with ssh sessions on Win2K3
I have a Win2K3 SP1 system, freshly installed with the latest bits, and
sshd installed with privilege separation (using ssh_host_config). The
/etc/passwd has both local and domain users (in that order), as does
/etc/group.
I have a local shared directory c:\Views (shared as \\myhostname\Views).
The problem is that when I log in as a domain user, and try to write
something into \\myhostname\Views\, I get a permission denied error,
even though I can do this successfully if I come in as that same user
via Terminal Services.
Here's a matrix of various file creation attempts I tried, logging in to
the server (I'm calling it "A" in the chart below) via TS or sshd, with
or without a password. For good measure, I logged in as the same
domain user, via sshd, to a different machine, and accessed the same
share successfully from there!
C:\Views \\A\Views \\Common\share
logged in to A via OK OK OK
Terminal Services
logged in to A via OK Fails OK
sshd, with password
passwordless pubkey OK Fails OK
ssh login to A
logged in to B (other -- OK OK
machine) via sshd,
as the same user
(with or without password)
What is special about accessing your own host's shares, when logged in
via sshd? sshd-logged-in users seem to be able to access shares on other
systems using normal rules; just not shares on their own system.
I've attached a cygcheck.out (from the passwordless pubkey login). Any
ideas on what I can try to make the two "Fails" cases above work?
(This is needed for Clearcase to be able to create views in that
directory. The stupid thing insists on using a share path for creating
views, even private ones).
