Chapter 3 Managing Your Storage System
46
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 of users
(both Windows/Mac OS X and Linux/other Mac users). By default, the 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 not Windows users. In addition, you cannot
create groups. All Windows users and groups are controlled 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 for
each user on the Active Directory 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
account. 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 differ by more than five minutes, errors
will occur whenever the storage system tries to connect to the Active
Directory server (that is, when you set the authentication mode, when
synchronization between the two systems occurs, and when users access
shared folders). You must adjust the storage system time, time zone, or both
to ensure that they match (as described in
“Changing the system settings” ).
Even if the 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 time. 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 Central Time zone (GMT-06:00), you
would set the storage system time zone to Eastern Time (GMT-05:00) and
then set the time to 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.
