How to Make Your Active Directory Work with Linux Devices

Microsoft Active Directory (AD) is the most common Windows-based user directory solution, and it鈥檚 baked into the IT infrastructures of many small and medium-sized enterprises (SMEs), despite being a legacy technology that struggles to support other platforms like Linux.

AD leverages LDAP under the hood, but it largely uses Kerberos as the authentication protocol for Windows machines. Because of this, Linux devices struggle to integrate with AD. Why is that important? AD serves key functions for access control: authentication, authorization, and management. If a business uses 100% Windows systems, AD accomplishes all three tasks.

However, AD starts to fail if a business uses any Android, Apple, or Linux devices; cloud infrastructure or applications, or non-Windows infrastructure that aren鈥檛 supported without modernization. Unmanaged devices and identities mean that resources aren鈥檛 being protected.

The good news is that you don鈥檛 have to replace AD altogether to solve this problem. It鈥檚 possible to modernize your existing infrastructure. This article shares several options that enable SMEs to manage their Linux devices/users, including enhancing AD with 黑料海角91入口.

If AD Fails, How Are Businesses Managing Directories?

There are several ways that organizations can connect their Linux devices to Active Directory. The easiest is by using LDAP via the PAM module that鈥檚 built into Linux. Organizations can also use Kerberos under this model. 

However, each of these approaches creates extra work and could add security issues (through increased attack surface area), instead of completely rectifying the issues where AD fails.

IT will also have to implement a dedicated authentication tool. This often requires heavy IT intervention and physical servers and exists independent of current identity practices and infrastructure.

It鈥檚 worth calling out that Microsoft鈥檚 supersedes and replaces AD鈥檚 tier model. The revised model spans AD installations, is multicloud, and includes users from several identity providers (IdPs) as opposed to a logical separation of AD assets in one domain. This approach fails to meet the requirements of that new reference architecture for AD.

Open Source Solutions

Another method is to leverage Samba and Winbind. This requires setting up Samba, which is no easy feat, and may require changes to the network perimeter. This approach relies heavily on VPNs, which can increase your attack surface area, and are an entrypoint into your network.

Winbind is used to resolve user and group information from Windows Server. PAM will provide authentication services.

It鈥檚 also possible to use OpenLDAP鈥檚 for integration with Active Directory. This isn鈥檛 a trivial setup and likewise increases IT management overhead and infrastructure.

Azure Active Directory and Intune

Microsoft recently added support for Linux to its Intune endpoint management service. Using Intune will obligate you to configure a hybrid server infrastructure that syncs AD with Entra ID (formerly Azure AD, or AAD). This can be significant work, and AAD is often bundled with Microsoft 365 and could obligate you to adopt a vertically integrated suite of Microsoft tools.

Additional Intune subscriptions may be necessary to manage your devices. Intune setup can be complex and Microsoft鈥檚 support for Linux is limited at this time. It imposes restrictions on which browser you may use, with Microsoft Edge as the sole option available to access your resources.

The Best Approach to Modernize AD for Linux

黑料海角91入口 is an open directory platform that unifies identity, access, and device management capabilities, regardless of the underlying authentication method or device ecosystem.

黑料海角91入口鈥檚 open directory platform provides an alternative approach to connecting Android, Linux, or Mac devices to Active Directory. It also has unified endpoint management.

This cloud directory platform acts as an 鈥渆xtension鈥 to AD, solidly fixing the areas where AD falls apart. It authenticates, authorizes, and manages all Android, Linux, Mac, and Windows devices. How? Active Directory Integration (ADI) is the key to making all it work.

How AD Integration and Modernization Works

黑料海角91入口 Architecture

黑料海角91入口鈥檚 AD Integration helps SMEs to reestablish strong access control.

Linux and Mac devices connect to 黑料海角91入口鈥檚 cloud-based directory platform via their native authentication mechanisms (and through an agent or mobile device management).

Users are added to 黑料海角91入口鈥檚 virtual identity provider either via our Active Directory Integration, or manually.

If Active Directory is connected through the 黑料海角91入口 AD Integration feature, then any updates in AD are automatically replicated to 黑料海角91入口 and, by consequence, to all Linux devices in the directory, too.

For example, a new user can be added in AD and as a result given access to all of their Linux cloud servers hosted at AWS. The reverse is also true where a user terminated in AD is automatically deleted from the AWS servers. This is accomplished by an active sync process between AD and 黑料海角91入口.

Linux devices can be easily connected to Microsoft AD through 黑料海角91入口鈥檚 hosted directory service. This eliminates the headaches associated with manual management or workaround solutions with Chef or Puppet.

黑料海角91入口 also supports , giving you the choice to work how you want to. This allows you to utilize the speed, stability, and security of Linux-based systems, without losing sight of what鈥檚 happening in the other operating systems your organization supports.

Other practical benefits include:

  • Eliminating the need for multiple passwords and siloed management
  • Reducing administrative or technical overhead
  • Reducing authentication friction and improving the end-user experience

Compliance and Security

黑料海角91入口 provides a collection of pre-built policies for Linux such as full-disk encryption. These policies help organizations to manage and secure their deployed Linux endpoints more efficiently while improving their overall security posture. Additional policies include:

  • Check partition and mount options: Directories that are used for system-wide functions can be further protected by placing them on separate partitions.
  • Check disk encryption: This policy will check a Linux machine for full-disk or home-directory encryption and report the status.
  • Disable USB storage: This policy prevents USB mass storage devices, such as flash drives and USB hard drives, from being used on the system.
  • Lock screen policy: The user’s screen saver will lock after the amount of seconds specified. A password will be required to unlock the screen saver. 
  • File ownership and permissions: Secure system files for Linux systems.
  • Network parameters: Enhance a system鈥檚 network security by setting kernel parameters for IP forwarding, packet routing, Internet Control Message Protocol (ICMP) requests, path filtering, and Transmission Control Protocol Sync (TCP SYN) cookies.
  • Disable unused filesystems: Prevent an unauthorized user from introducing data into or extracting data from a system. An admin can now determine if a filesystem type isn鈥檛 necessary and disable it.

The open directory platform is also a great directory choice for organizations that don鈥檛 use AD but would like to manage their Linux devices in a similar way.
