This has to do with the way many Windows applications work. When a file is opened the application typically operates on a temporary copy of the original file. The temporary file is of course owned by the user that just created it. When the file is saved, the original file is renamed to become a backup file, and the temporary file is renamed to the original file name. That's how the ownership changes.

Has anyone had the problem of Microsoft Word or Excel file writes taking over ownership of a file?

I have a 720 at OS version of 5.1.2R3 running both the NFS and CIFS protocols. The filer contains only the root volume which has multiple qtrees of UNIX style security.

Scenario:

CIFS user#1 creates a Microsoft Word document which has write access at the UNIX group level. CIFS user#2, who is in the same UNIX group, modifies the file and automatically becomes the UNIX owner of the file.

This works the same for Excel documents but not for text documents using Notepad.

All help is appreciated.
