Active Directory and DNS

If you plan to use Active Directory, the servers must be able to resolve hostname and server records in the Active Directory portion of the domain namespace. For example, if your appliance resides in the domain example.com and the Active Directory portion of the namespace is redmond.example.com, your nameservers must be able to reach an authoritative server for example.com, and they must provide delegation for the domain redmond.example.com to one or more Active Directory servers serving that domain. These are requirements imposed by Active Directory, not Oracle ZFS Storage Appliance itself. If they are not satisfied, you will be unable to join an Active Directory domain.

Note:

With software version OS8.6.0 and later, if the primary DNS domain suffix does not match the DNS name of the Active Directory, the configuration results in a disjoint namespace. If you do not want a disjoint namespace, ensure that the DNS domain and the Active Directory domain are the same.
