Note some of the environment related requirements:
1.
Time
(namely, the time server settings) must be accurate between AD server and the
NAS server.
2.
DNS
servers,
NetBIOS
, and
domain
values have to match those on the AD server.
For example, you should check on System > Network, to ensure the NAS server is
joined into same network as the AD server. The DNS server in the network can be
pointed to the same physical address of the AD server.
Please note the following: to join an AD domain, the server must be setup so that the
Active Directory Domain and the server are in the same DNS Domain. In general, one
key element in the Active Directory functionality is its DNS infrastructure. You can refer
to Microsoft Knowledge Base article - "Troubleshooting Active Directory—Related DNS
Problems." The problems may include DNS server and zone configuration, and presence
of DNS domain controller locator records (SRV records).
Optionally, you can add users/groups that will use this shares on this server and will
perform join operation. Check on Account > Permission, type in user (or group) name that
are identical to those setup on the Windows AD server.
To join a
Windows Active Directory
:
1. Select the Enable Windows Active Directory checkbox.
2. Enter the Domain Controller (name of the AD server), such as server2012.
3. Enter Domain name (DNS/Realm)
4. Enter the NetBIOS name.
In the Organizational unit field, you can enter a smaller organizational unit under a
large AD architecture to minimize the complexity of the configuration; e.g., Asia/China/
Shanghai.
OU: A particularly useful type of directory object contained within domains is the
organizational unit. Organizational units are Active Directory containers into which you
can place users, groups, computers, and other organizational units. An organizational
unit cannot contain objects from other domains.
OU
: An organizational unit is the smallest scope or unit to which you can assign Group
Policy settings or delegate administrative authority. Using organizational units, you can
create containers within a domain that represent the hierarchical, logical structures
within your organization. You can then manage the configuration and use of accounts
and resources based on your organizational model. For more information about Group
Policy settings, see Group Policy (pre-GPMC).
5. Enter the AD administrator's name.
6. Enter the password.
7. Enter the password again to confirm.
8. Click the Apply button. The server should take several minutes to acquire accounts from
the AD server.
If preferred, click the checkbox below to remove existing Domain user and UID mapping.
