Prepare for authentication
There are three security modes that you can use to authenticate users/groups
trying to access NAS shares.
Share mode - Authentication is done by a set of passwords (one
full access
password and one
read only
password) that are set from the Console. This
mode does not use an authentication server.
Domain mode - The authentication server must be a Primary Domain Controller
(PDC) for pure Windows NT or mixed Windows NT/2000 domains, or a Domain
Controller for native Windows 2000 domains. The ASC Server and all NAS
clients must belong to the domain controlled by this PDC/Domain Controller.
Before you activate
Domain
mode, you will need to create a computer account
for the ASC Server in the domain.
• For a Windows 2000 domain, create the account for the ASC Server
from
Admin strative Too s
-->
Act ve Directory Users and Computers
-->
Computers.
After creating the account, right-click on the created
account and select
Reset Account
. If the computer account for the ASC
Server has already been created in the domain, right-click the account
and select
Reset Account
, to join the domain again.

• For a Windows NT 4.0 domain, create the account for the ASC Server
from
Admin strative Too s
-->
Server Manager for Domains.
If the
computer account for the ASC Server already exists in the domain, you
have to delete the ASC Server account and then add the server again.
NOTE: If you ever need to replace your ASC Server (i.e. you replace the server’s
hard disk), you will need to reset/re-create the computer account for the ASC
Server so that it can authenticate itself in the domain.
Server mode - Any Windows NT (Server or Workstation), or Windows 2000
(Server or Professional) computer (including a PDC/Domain Controller) can be
used to authenticate users.
If you are not using a PDC/Domain Controller for authentication, group
information stored on the PDC/Domain Controller cannot be accessed. Only
the users in this server (not including local users) are valid users.
If you use a PDC/Domain Controller for authentication, the ASC Server does not
need to log into the NT domain controlled by the PDC/Domain Controller.
NOTE: It is important that you do not change your authentication mode once
you begin using your NAS system. If you do change it, you will lose all of your
Windows client assignments and/or passwords.
