Joining a domain in a production environment
In smaller organizations or organizations where individual users have permission to join their own workstation to the Active Directory domain, you can run the adjoin command interactively on individual computers. This option works well when computers are distributed across many different domains or when individual users are joining their own workstation to the domain.
In larger organizations, however, you may want to use a custom script to remotely join a group of UNIX computers to an Active Directory domain. If you develop a custom script for joining a domain, the script should restart services or reboot the computers where it runs.
After joining a domain, you should monitor computers closely for a few days before extending the deployment to additional computers.
If the join operation fails or users cannot log on, you can run the adleave command to restore the computer to its previous state.
