When you configure the CIFS protocol, you must choose whether the filer uses PC-
style or UNIX-style permissions.
NOTE: If you are setting up a filer in a Windows NT-only environment, you can skip
this section.
This section provides a brief overview of PC-style and UNIX-style permissions and
provides guidelines for choosing which style to use. PC-style permissions are similar
to FAT (File Allocation Table); they maintain security with share level ACLs (Access
Control Lists).
In addition, PC-style permissions also allow you to further restrict file security using
file permissions. UNIX-style permissions do not use share level ACLs. Therefore,
using PC-style permissions only affects PC access to files with UNIX security.
