DataSafe NAS User’s Manual 

69

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.

 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, 

 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, 

 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 

, you can obtain 

UNIX user, password, and group information from one 
or more NIS servers, or from imported password and 
group files.
