[Samba] Dreamweaver access errors with Samba 3.0.23d

Dear list

Our environment uses Samba to store user directories. I recently
upgraded Samba from 3.0.14a to 3.0.23d. After this, we discovered that
Dreamweaver MX had trouble writing to an existing file; a file could be
created and saved, but saving again after changes produced a "Permission
denied" error.

There was a similar problem mentioned on the list a few years ago. The
suggested solution was to force dos handling of the file modification
dates, and explicit permissions, as follows:
dos filetimes = yes
dos filetime resolution = yes
dos filemode = yes
fake directory create times = yes
create mask = 0112
force directory mode = 0775
inherit permissions = Yes

But this didn't fix the problem either.

I have tried version 3.0.22, and this *works*. I can't see anything in
the changelog that would cause this, aside from
  o New handling of unmapped users and groups.

Has anyone encountered this? And found a fix?

log.smbd follows.

Regards
Austin
