Join your Qumulo Cluster to Active Directory


  • Cluster running Qumulo Core
  • Details for your domain including Domain name, Domain username, and Domain password

NOTE: Qumulo Core only supports joining a cluster to one Active Directory Domain.


  • Login to the Qumulo Core Web UI
  • Hover over the Cluster menu and click Active Directory under Authentication and Authorization


  • Fill in the following mandatory fields:
    • Domain Name: name of your domain. Example:

    • Domain Username: the user account or service account you will use to authenticate against the domain

    • Domain Password: the password for the user account or service account

  • Fill in the following two optional fields:
    • NetBIOS name: If your Domain’s NetBIOS name is different from your domain name then enter the Domain’s NetBIOS name in this field.
      NOTE: If you attempt to join the Domain and get an error message similar to this "Sorry, the NetBIOS name (QUMULO) is incorrect." then your Domain’s NetBIOS is different from your Domain name.
    • Organizational Unit (OU): If known, this information can be entered and can normally be obtained from your Systems Administrator. If unknown, leave it blank and Qumulo will attempt to join the domain without an OU specified.


  • Click the Yes button to use your AD as your primary time server
  • Select the option to use Active Directory for POSIX attributes: 
    • Use in environments where 'user objects' in Active Directory are assigned UNIX UID and GID attributes to allow the cluster to properly enforce permissions regardless of the protocol used to access the data 
    • For additional details, see the Using Active Directory for POSIX attributes article
  • If desired, enter your Base DN(s) in the field provided


  • Click Join

NOTE: DNS entries will be automatically created from the node used to add the cluster to Active Directory and can be removed without issue.

  • Examples values would be better, as would explaining what each of the fields do.  The UI is confusing, because it calls a domain name, but that looks like a server name?
