DataSafe NAS User’s Manual 69
User and Group Mappings
In order to provide security for DataSafe NAS files
accessed from a UNIX environment, the NFS service
requires the system administrator to map UNIX user or
group accounts to their twin accounts on the DataSafe
NAS. Users then have equivalent access rights under
UNIX as they have under Microsoft Windows.
Alternatively, sites with less stringent security needs
can bypass the mapping procedure and treat all UNIX
users as anonymous users.
User And Group Mappings lets you create maps
between Windows and UNIX user and group accounts
even though the user and group names in both
environments may not be identical. Perhaps most
important,
User and Group Mappings lets you
maintain a single mapping database for the entire
enterprise.
In addition to one-to-one mapping between Windows
and UNIX user and group accounts,
User and Group
Mappings permits one-to-many mapping. This lets
you associate multiple UNIX accounts with a single
Windows account, or multiple Windows accounts with
a single UNIX account. This can be useful, for
example, when you do not need to maintain separate
UNIX accounts for individuals and would rather use a
few accounts to provide different classes of access
permissions.
You can use simple maps, which map Windows and
UNIX accounts with identical names. You can also
create advanced maps to associate Windows and
UNIX accounts with different names, which you can
use in conjunction with simple maps. Furthermore,
with
User and Group Mappings , you can obtain
UNIX user, password, and group information from one
or more NIS servers, or from imported password and
group files.
