Managing Your Ethernet Disk RAID
5.4.5. Authentication Mode
■
Your LaCie Ethernet Disk RAID can operate in
one of two modes:
• Local authentication mode
• Active Directory authentication mode
In local authentication mode, the storage system au-
thenticates all users who try to connect to shared fold-
ers, and you can add, modify, or remove all types of us-
ers (both Windows/ Mac OS X and Linux/other Mac
users). By default, the Ethernet Disk RAID 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 us-
ers. In addition, you cannot create groups. All Windows
users and groups are controlled entirely by the Active
Directory server.
TeChNICAl NOTes:
The authentication mode has no effect on backups performed using Windows Backup Software.
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.
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.
Active Directory authentication mode does not automatically include a guest account. However, the Active Direc-
tory administrator can create one on the Active Directory server.
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 when 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). It is recommended that you configure both the storage system and the
Active Directory server to set their clocks from a common Network Time Protocol (NTP) server.

You can change the authentication mode at any
time, but you must provide the administrator password
to do so.
CAUTION:
Changing the authentication
mode deletes all your existing user data and
shared folder assignments. However, if any users
are currently accessing shared folders, they will
remain connected until they disconnect from the
shared folders or shut down their computer.
