Comparison
Zentyal vs a self-managed Samba AD
Both give you an Active Directory domain on Linux. Zentyal delivers it as a supported product with DNS, Kerberos, file sharing, mail, VPN and firewall already integrated; a hand-built Samba deployment gives you the same protocols and leaves the integration, upgrades and support to you.
The short answer
Choose raw Samba if you have Linux administrators with time to own the domain, enjoy configuring DNS and Kerberos by hand, and are comfortable planning your own major-version upgrades. Choose Zentyal if you want the same open-source foundation delivered as a tested release, administered from one web interface, with mail and gateway services in the box and a support team on the other end of a ticket.
Side-by-side comparison
| Area | Zentyal Server 8.1 | Self-managed Samba AD |
|---|---|---|
| Initial provisioning | Guided installer, domain up in under an hour | Manual samba-tool provisioning and DNS decisions |
| DNS and Kerberos | Configured and kept in sync automatically | Choose internal DNS or BIND9_DLZ and wire Kerberos yourself |
| Group Policy and sysvol | Managed, with replication handled by the platform | sysvol replication is not built in; usually scripted with rsync |
| Mail and groupware | Included and integrated with domain accounts | Separate project — Postfix, Dovecot, SOGo configured by hand |
| Firewall, VPN, proxy | Included in the same interface | Separate packages and configuration files |
| Web administration | Single interface for every module | Command line, plus third-party tools |
| Upgrades | Included in the subscription, tested per release | Self-managed, including major version jumps |
| Support | Commercial SLA from 4 business hours | Community mailing lists and forums |
| Cost | $230–$3,600 per server per year, or lifetime from $460 | No license cost; administrator time instead |
Where the time actually goes
The provisioning step is the easy part of a Samba domain. The recurring cost sits in sysvol replication between domain controllers, certificate and Kerberos renewals, keeping DNS authoritative for the domain, and the major-version upgrade every couple of years. Zentyal absorbs those tasks into the release and support cycle, which is what the license pays for.
Frequently asked questions
+Is Zentyal just Samba with a web interface?
Zentyal uses Samba for its Active Directory implementation, but the product is the integration: provisioning, DNS, Kerberos, certificate authority, file and print shares, mail, VPN and firewall are configured together and kept consistent by one management layer, and the whole stack is tested and packaged for each release.
+Can I build the same thing myself with Samba?
Yes, and many administrators do. The trade is time and risk: you own the provisioning, the BIND or internal DNS choice, Kerberos keytabs, sysvol replication, backup and — above all — the version upgrades. Zentyal packages that work and backs it with a support SLA.
+What does Zentyal add beyond Active Directory?
A complete mail and groupware stack (SMTP, IMAP, webmail, calendars, contacts, ActiveSync, antispam), network services (DNS, DHCP, firewall, VPN, HTTP proxy, certificate authority) and file sharing, all administered from the same interface as the domain.
+How are upgrades handled?
Zentyal commercial editions include software and security updates plus upgrades to new versions for the life of the subscription. On a self-managed Samba deployment, major-version upgrades and schema changes are your responsibility.
+Can I get commercial support for Samba AD through Zentyal?
Yes. Commercial Zentyal editions include access to the Zentyal support portal, with response times from 4 business hours on Enterprise. Single support tickets are also available for one-off issues on a licensed server.
