On Mac, the NSS files and folders with ZID numbers greater than 32-bit are not listed when the NSS volume is mapped through AFP. For more information, see NSS64 ZID Support in the OES 11 SP3: NSS File System Administration Guide for Linux.
The owner’s name is not displayed when you right-click a folder.
File level trustees might be deleted when a file is modified, depending on how the application works with files it opens for writing. Some third-party applications record changes in a temporary file in order to save internal memory or as a safety net to prevent data loss due to a power failure, system crash, or human error. When a user saves the changes, the application deletes the original file, and saves the temporary file with same name as the original file. In response to the deletion instruction, the file system deletes the original file as well as any file level trustees set on the file. The file system is not application aware; that is, it does not track the ultimate intent of the applications that you might use.
