This article continues our series on helpful commands for every Mac admin. The first article in the series explored how to enable SSH to access a remote Mac’s Shell securely while the second article examined how to change the computer name, hostname, and local hostname.
Active Directory (AD) provides crucial user and device management capabilities as an identity provider for IT systems. However, many IT admins find it challenging to manage Macs with Active Directory. Given that Active Directory is a sought-after identity and access management solution, IT admins must still face the challenge of integrating it effectively with macOS.
This article will examine how you can join a Mac to Active Directory services via the use of a command in the terminal app.
What Is a Directory Service and What Is Active Directory?
Before delving into Active Directory, it is critical to understand what directory services are all about. Simply put, directory services organize and manage users and IT resources within a network and enable administrators to granularly control user access to those IT resources. For instance, employees in the marketing department would have access to sales content but would be restricted from accessing financial information.
A directory can be defined as the ultimate source of truth used in verifying a user identity, and maintains information such as user ID, group membership, SSH keys, passwords, and other unique identifiers.
Directory services own the authentication and authorization process. They verify users’ identities (authentication) against the directory’s user database. If the specific access credentials provided match the credentials in the database, a user is granted access (authorization) to their respective IT resources. Otherwise, the user is denied access, which makes directory services a key cybersecurity tool.
Active Directory, a common identity provider, was developed by Microsoft. It pioneered the era of identity management at a time when the majority of IT infrastructure was Windows-based and managed on premises.
With AD in place, IT admins can connect users and/or groups to IT resources and control policies. The information stored in Active Directory includes users, groups, networks, digital assets, systems, and applications. It also defines the relationship between those entities.
How to Join a Mac to Active Directory Services via Terminal
There are several ways to bind a Mac into Active Directory services. Methods include running a command in the terminal app, using Apple Directory Utility, or using a cloud identity bridge. In this section, we will explore how to connect Mac to Active Directory services using the terminal app.
- Launch the terminal app on your Macbook.
You can do this by searching “terminal” using the Spotlight search option on your computer or navigating through Applications > Utilities > Terminal.
- Enter and run the command.
You can use the
dsconfigad command to bind a Mac to Active Directory via the terminal app. All you need to do is run the following command. Note that you need to replace the domain name, computer name, password, etc. with your specific information.
sudo dsconfigad -preferred <adserver.example.com> -a <computername> –domain example.com -u administrator -p <password>
The arguments in the command are explained as follows:
-a: This adds your computer to the Active Directory. Replace
<computer-name>with your actual computer name.
-u: Specifies the admin username that has the rights to bind the Mac to AD. Replace
<username>with your computer’s username.
-domain: States the domain name of the domain you want to join. Replace
example.comwith the domain you want to join.
After you have binded a Mac to the domain, you can also use
dsconfigad to set the admin options in Directory Utility by running the command below:
Using Mac’s Built-In Apple Directory Utility
One of the services in Apple Directory Utility is Active Directory Connector which generates all the necessary attributes for macOS authentication from AD user accounts. It also supports AD authentication policies like password changes, expirations, and security options. You can take the following steps to bind Mac to Active Directory using the utility.
- Navigate through System Preferences > User & Groups.
- Click the lock icon and provide your user password.
- Click Login Options (Figure 1).
- Next to Network Account Server, click Join (Figure 1).
- A pop-up shown in Figure 2 will appear. Click Open Directory Utility as shown in Figure 2.
- Type your Active Directory domain and click Bind (Figure 3).
Binding a Mac to Active Directory enables macOS access to the legacy identity management solution. In this article, we have explored how you can join a Mac to AD services either through the terminal app or via the use of Apple Directory Utility.
Another option for a more seamless connection is to leverage a cloud identity bridge, i.e., a bridge that allows you to extend AD-bound identities to IT resources unable to directly bind to AD, such as Mac devices, Linux servers, remote Windows machines, and web applications.
While historically it was possible to layer together multiple point solutions to act as that bridge, today’s IT environments have become much more complex as the cloud has matured and remote work has gained prevalence. The JumpCloud Directory Platform was built to eliminate this complexity and empower modern IT admins to build connections between all of their IT resources with a single cloud-based console.
If you’re not ready to replace AD altogether, then JumpCloud’s Active Directory Integration could be the answer. This lightweight approach integrates with a cloud-hosted directory service that allows IT admins to have full user and device control over their Mac fleet, as well as Windows and Linux devices.
