3 Managing Your Storage System

In local authentication mode, the storage system authenticates all users who try to
connect to shared folders, and you can add, modify , or remove all types o f users
(bo
t h Windows/Mac OS X and Linux/other Mac users). By defau lt, t he storage
system
uses local authentication mode.
In Active Directory authentication mode , the Active Directory server authenticates
all Windows users who try to connect to shared folders. You can add, modify , or
remove
Linux /other Mac users, but no t Windows users. In addition , you cannot
create
groups. All Windows users and groups are con t rolled entirely by the Active
Directory
server .
Notes:
l The authentication mode has no effect on backups performed using DiskSafe
Express.
l If you use Active Directory authentication mode, the User must change
password
at next logon check box must be cleared in the properties f or
each user on t he Ac t ive Direc t ory server who will be accessing shared folders on
the storage system. In addition, each user’s password can be no longer
than 24 characters.
l If you use Active Directory authentication mode , you must add any Mac OS X
users
to your Active Directory server in order to provide those users with access
to shared folders on the storage system.
l Active Directory authentication mode does not automatically include a guest
accoun
t. However , the Active Directory administrator can create one on the
Active
Directory server .
l If you use Active Directory authentication mode, and the clocks of the storage
system
and the Active Directory server dif f er by more than five minutes, errors
will
occur whenever the storage system tries to connect to the Active
Directory server (tha t is, when you set the authentication mode , when
synchronization
between the two systems occurs, and when users access
shared
f olders). You must adjus t the storage system time, time zone , or both
to ensure that they match (as described in “Changing the system settings”).
Even if t he storage system and Active Directory server are in the same time
zone
and have the same time, errors might still occur if the Active Directory
server
adjusts for daylight savings ti me. In this case, you must change both
the
time zone and time on the storage system. For example, if the Active
Directory server time is 2:00 P . M. in the Cen t ral Time zone (GMT-06:00), you
would
se t the storage system time zone to Eastern Time (GMT-05:00) and
then se t the time t o match the Active Directory server (14:00). If you do this,
do not synchronize the storage system with an NTP server , as the time will be
readjusted
based on the time zone .
