NTFS User access is determined as follows:
CIFS requests: Windows NT permissions
determine user access if Windows NT
permissions have been set on a file.
NFS requests: Windows NT permissions
and a mapped CIFS identity determine
access. UNIX groups are not used in the
mapping from a UNIX identity to a CIFS
identity\.
NOTE: You cannot change permissions in
an NTFS qtree from a UNIX client.
Windows NT per-
missions determine
file access for a file
that had them if the
change is from a
mixed qtree. Other-
wise, UNIX-style
permission bits
determine file
access for files cre-
ated before the
change.
UNIX User access depends on the protocol, as
follows:
CIFS requests: Windows users are
mapped to a UNIX UID and UNIX permis-
sions determine access.
In a UNIX qtree, a user cannot set Win-
dows NT permissions. A Windows user
can change UNIX permissions from Win-
dows using SecureShare Access, as
described in Sending a Message to All
Users on a Filer in Chapter 7.
NFS requests: Only the users UID, GID,
and UNIX-style permission bits of the file
or directory determine user access.
The filer disregards
any Windows NT
permissions estab-
lished previously.
mixed Both NTFS and UNIX style permissions
are permitted. The security style of a file is
the style most recently used to set per-
missions on that file. See the NTFS
information in Types of Security Styles.
