After the install has completed, it’s time to join the domain. To successfully join, the following is required:

1. Access to an AD user with rights to join the domain.

2. The Fully Qualified Domain Name (FQDN) of the domain you want to join.

3. DNS must be set up correctly on the domain.

Type the following command to join the domain:

domainjoin-cli join example.com Administrator

Where example.com is your domain name and Administrator is the user name of the account with the rights to join the domain.

After joining the domain, you must reboot before trying to authenticate with a domain user. Type:

reboot

** If you receive the error:

The configuration stage ‘open ports to DC’ cannot be completed automatically.
Please manually perform the following steps and rerun the domain join:

Some required ports on the domain controller could not be contacted. Please
update your firewall settings to ensure that the following ports are open to
dc.domain.com:
    88  UDP
    389 UDP
    464 UDP
    123 UDP

Make sure the Windows Time service is running on the domain controller.

After successfully joining to the Active Directory domain you can authenticate using any valid AD user. To login you will need to enter the user name as ‘domain\username’. For example to SSH to a server joined to the domain enter:

ssh ‘example\username’@hostname
To leave the domain, type:
domainjoin-cli leave
