We have some files on our Samba-shared directory which are accessed by more than two groups. All the groups can read and write to the files. We're noticing some quirks with some Windows applications, particular MS Office 97 and Visio Pro 4.5. For example, when a MS Word 97 file that's owned by UserA/GroupA is modified and saved by UserB/GroupB, the owner of the saved file is changed to that of the last person that edits it (i.e. the new owner is UserBGroupB). What we want is for the owner to remain the same, i.e., the user and group ownership should belong to the first person that creates the file. I don't think this is a Samba problem. I think the application is the culprit -- MS Office. When an MS Office 97 application opens a file, it renames the original file (essentially creating a backup) and creates a NEW file with the exact same name as the original file. When the user saves the opened file, MS Office 97 (such as Word) deletes the backup copy. Essentially, Office 97 applications creates a new file even when it's editing an existing file, that's why the ownership and permissions change to that of the last person who edits the files. Does anyone see a way around this? As mentioned, what we want is for the ownership and permission to remain unchanged, i.e., we don't want the permission to change to that of the last person who edits the file. Any help would be appreciated.
