PC-style permissions are determined by the rights assigned in a shares ACL and are
limited by the UNIX permissions assigned to a file. To write to a file when PC-style
permissions are in effect, a user must meet the following criteria:
The user must have write permission for the file in the ACL.
The user must have write permission for the file according to the UNIX-style per-
missions associated with the file.
If the user is the owner of the file, the filer uses the UNIX-style permissions set
for the owner of the file. If the user is not the owner of the file, the filer uses the
UNIX-style permissions set for the UNIX group associated with the file. Note that
the UNIX "other" permissions are not used.

UNIX-style permissions are determined by the rights associated with the UNIX UID
and GID and are limited by the ACL permissions assigned to a file. To write to a file
when UNIX-style permissions are in effect, a user must meet the following criteria:
If the user is the owner of the file, the write permission for the users UID must
be set.
If the user is not the owner of the file, he or she must be a member of the group
(GID) associated with the file and the write permission for the groups GID must
be set.
The user must have write permission for the file in the ACL.

Choose UNIX-style permissions if you want to implement simple security and need
access to be controlled using exact UNIX rules.
NOTE: If you choose UNIX-style permissions, set the share ACL permission to
rwx
for everyone. With this setting, the UNIX rights work just as they do on a UNIX
system.
