Mac OS X Server v10.5: Permissions issues when using Microsoft Excel "Share Workbook" feature on SMB share point

When using the "Share Workbook" feature of Microsoft Excel with an Excel file stored on a Mac OS X Server v10.5 SMB share point, the permissions of the file may unexpectedly change.
This article has been archived and is no longer updated by Apple.

Use these advanced steps on the server hosting the SMB share:

  1. Open the /etc/smb.conf file in the text editor of your choice. This will require administrator access (sudo or root).
  2. After the ";END required configuration" line, add the following text:

    nt acl support = no

  3. Save the file.
  4. Open Terminal (/Applications/Utilities).
  5. Execute this command:

    sudo killall -HUP smbd
