Active Directory Domain Controller (AD DC) is a core component in networked environments that provides centralized authentication and authorization services. It manages user accounts, security policies, and access to resources across a domain using the Active Directory database. AD DC can be implemented on both Windows servers and Linux systems using Samba.

Features of AD DC:

• Centralized authentication for users and computers within a domain.
• Management of security policies, permissions, and access control.
• Supports LDAP, Kerberos, and DNS integration.
• Compatible with Windows and Linux clients.

To check Samba AD DC version, run: $ samba -V.
