Course Overview

The Samba4 as AD Domain Controller course by Samba is designed for IT professionals seeking to deploy and manage a fully functional Active Directory environment using open-source technology. While there is no formal certification exam directly tied to Samba4, this training aligns with enterprise-level directory services administration and supports preparation for broader Linux and systems administration credentials such as LPI 300. It serves system administrators, infrastructure engineers, and network administrators responsible for hybrid environments integrating Linux and Windows systems. According to IT Jobs Watch, Active Directory skills were cited in over 2,800 permanent UK job postings in the six months leading up to mid-2026, with a median salary of £40,000, underscoring sustained employer demand for directory services expertise.

This course covers core technologies including Samba4, LDAP, Kerberos, DNS (via Samba’s internal DNS backend), NTP, and Group Policy Objects (GPOs). Students engage in hands-on labs where they build a complete Active Directory Domain Controller from scratch on Linux, using tools like `samba-tool domain provision` and `samba-tool domain join`. The lab environment simulates real-world deployment scenarios on local virtual machines or cloud instances, guiding learners through configuring DNS resolution, setting up secure authentication, enabling RFC2307 Unix attributes, and establishing domain replication. A key project involves provisioning a primary DC, joining secondary DCs, and verifying cross-platform client integration with both Windows and Linux machines, ensuring operational readiness in mixed-network infrastructures.

By mastering Samba4 as an AD Domain Controller, participants gain skills recognized across enterprise IT environments seeking cost-effective alternatives to Microsoft Windows Server licensing. Graduates are well-positioned for roles involving identity management, systems administration, and infrastructure modernization, with Active Directory–skilled professionals earning median salaries of £40,000 in the UK and higher in specialized or cloud-integrated roles. Koenig Solutions enhances learning with Guaranteed-to-Run live training, official courseware, and flexible 1-on-1 instructor support, ensuring deep technical mastery. Upon completion, learners can lead deployments of secure, scalable, and license-compliant directory services in on-premise, hybrid, or cloud-based networks.
