[Samba] Dreamweaver access errors with Samba 3.0.23d
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 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.
