The function works on non-NTFS filesystems.  You, yourself, noted that
it works on directories exported from a Samba server.  It also works on
Windows 9x which doesn't natively understand NTFS filesystems.

It apparently doesn't work on a Novell netware drive.  That's been noted
repeatedly here.  It sounds like a netware bug to me.
