Active Directory for UNIX, Linux and Mac

Extend the authentication, authorization and administration infrastructure of Active Directory to the rest of your enterprise. This tool enables UNIX, macOS and Linux Active Directory authentication to operate non-Windows systems as full AD citizens.

Audit, alerting and change tracking

Authentication Services enables you to alert on, audit, and show in-depth change history of UNIX-centric information being managed by Active Directory.

Group Policy for UNIX, Linux and Mac

Extend policy-based management (through Windows Group Policy) to non-Windows systems, including Group Policy for macOS using the product’s patented framework.

Single sign-on (SSO)

Implement “Kerberized” and LDAP SSO to UNIX, Linux and macOS systems in the same way they’re used in Windows. You also get out-of-the-box single sign-on for a variety of applications, including Siebel, SAP and DB2.

Simplified identity and access management

Maximize the value of your investment in Active Directory and AD-optimized identity administration tools while dramatically simplifying your existing security framework, meta-directory or synchronization solution.

NIS migration and directory consolidation

Streamline the process of extending UNIX/macOS/Linux Active Directory authentication to non-Windows systems and users. Simplify migration from multiple authentication mechanisms (including NIS), directories and identities to a single AD-based infrastructure.

Deployment flexibility

Options range from a non-impact, "schema-less" deployment to a fully rationalized environment, enabling you to deploy Authentication Services that ideally suits your objectives, environment, timelines and challenges, such as Linux Active Directory authentication.

Two-factor authentication support

Enhance security by requiring two-factor authentication for your UNIX/Linux users and administrators. In addition, Safeguard Authentication Services extends Windows-based smart cards to UNIX and Linux and supports third-party OTP solutions.


Authentication Services includes the following components:

  • Unix Agent
  • Windows Management Tools
