The file DATA.DOC has the following security descriptor on the Windows NT computer:
Notice that NtUser4 is not mapped. Because there is no network file system (NFS) mapping for the Windows NT user NtUser4 and the Windows NT group NtGroup4, the unassigned user ID (Nouser) and group ID (nogrup) are used. The owner (NtUser4) has full permissions, according to the discretionary access control list (DACL). Since the group NtGroup4 does not have explicit permissions, the group permissions are the same as those for Everyone. The UNIX permissions are listed on the client as follows:
-rwxr-xr-x Nouser nogrup 64 Nov 2 14:40 data.doc
