Managing HP-UX File Access Permissions from Windows NT/XP/2000
UNIX File Permissions and POSIX ACLs
Chapter 3 49
If you use pre-defined NT access types to set permissions on a Samba
share, the permissions that are displayed later will not match what you
set in NT.
For example, Full Control will become rwx on the Samba server, and
when it is displayed on the Windows NT client, it will show up as Special
Access (RWX).
