• 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.
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.
To change the authentication mode:
1. In the navigation bar, click “Users”.
2. In the left pane, click “Authentication Mode”. The Authentication Mode page (Figure 3-11)
displays the current authentication mode.

3. In the Administrator password text box, enter the password for logging into the freeStor
4020.
4. Click “Change Authentication Mode”.
5. If you are changing to Local authentication mode, all your existing user data and user
assignments are deleted, and you can add new users and groups manually and assign them
to shared folders.
6. Otherwise, if you are changing to Active Directory authentication mode, you will have to
enter information about your Active Directory server on the next screen (Figure 3-12). Note
that all existing Windows and Mac OS X users will be deleted along with their home folders.
