UNIX File Permissions and POSIX ACLs
The HP CIFS Server enables the manipulation of UNIX file permissions
or VxFS POSIX ACLs from Windows NT, XP or Windows 2000 clients.
With this capability most management of UNIX file permissions or
POSIX ACLs can be done from the familiar Windows Explorer interface.
NOTE Although concepts of file ACLs are similar across the Windows and
HP-UX platforms, there are sufficient differences in functionality that
one cannot substitute UNIX ACLs for Windows ACLs (i.e. full emulation
is not provided). For example, a Windows application that changes the
ACL data of a file may behave unexpectedly if that file resides on a HP
CIFS Server.
Viewing UNIX Permissions From Windows NT
As a result of the ACL data differences in NT and UNIX file permissions
and VxFS POSIX, Samba must map data from UNIX to NT and NT to
UNIX.
The table below shows how UNIX file permissions translate to Windows
NT ACL access types:
Table 3-1
UNIX Permission NT access type
r-- Special Access(R)
-w- Special Access(W)
--x Special Access(X)
rw- Special Access(RW)
r-x Read(RX)
-wx Special Access(WX)
