Samba AD for small business: what it does and what it can't

Samba can act as an Active Directory domain controller that Windows PCs join. It is not a full copy of Windows Server. Here is what it does, what Samba's own documentation says is missing, and how a NetYard plan works around each gap.

What it does for a small shop

  • Windows 10 and 11 PCs join the domain and each person signs in with one password
  • Shared drives by team and a home folder per person
  • Group Policy, edited from a Windows PC with Microsoft's free RSAT tools
  • DNS for the office network
  • No client access licenses. Samba and Debian are free and open source

What Samba's own documentation says (checked October 19, 2026)

  • The Samba wiki FAQ says Samba AD is stable for production and that AD domain controller support arrived in version 4.0, released in December 2012.
  • The same FAQ says some features are unimplemented, such as Sysvol replication: Samba does not support the DFS-R protocol Windows uses to copy Sysvol between domain controllers.
  • It also says the Samba AD DC file service does not support network browsing, so Network Neighbourhood can look empty.
  • Samba's security documentation says password changes on a Samba read-only domain controller are rejected rather than passed on to a writable one.

How NetYard plans around each gap

GapWhat NetYard does
On-premises ExchangeEmail stays in Google Workspace or Microsoft 365
Microsoft Enterprise CANot planned. We raise it on the call if a program needs one
Read-only domain controllersNot planned for a single small office
Sysvol replication between DCsRaised on the call if you need a second domain controller
Network browsingShares are mapped by group, so nobody has to browse for them
Windows-only server programsListed on the free call, before anything is bought

What NetYard does

NetYard writes the plan for free: addressing, a Samba Active Directory on Debian that Windows PCs join, shared drives by team, guest Wi-Fi on its own network, a WireGuard VPN stub, a shopping list, install scripts, a user CSV, and a runbook. If you would rather not run it yourself, First Deploy AI builds it from that same written plan for $1,750 setup ($875 to start), then $250/mo. Hardware is bought separately.

Stay on Windows Server if

  • You need on-premises Exchange or a Microsoft Enterprise CA
  • You run several sites that need read-only domain controllers
  • A line-of-business program only runs on a Windows server

A Samba plan fits if

  • One office, Windows PCs, shared drives, and printers
  • Email already lives in Google Workspace or Microsoft 365
  • You want to stop buying CALs

Questions

Is Samba AD stable enough for a small business?

The Samba wiki FAQ says Samba AD is stable for production environments, with AD DC support since version 4.0 in December 2012. Checked October 19, 2026.

What can Samba not do?

NetYard does not plan on-premises Exchange, a Microsoft Enterprise CA, or read-only domain controllers on Samba. Samba's docs also list Sysvol replication and network browsing as unimplemented. Email stays in Google Workspace or Microsoft 365.

Can Windows PCs still get Group Policy?

Yes. Windows PCs joined to a Samba domain receive Group Policy, and you edit policies from a Windows PC with Microsoft's free RSAT tools.
