Zentyal is an Easy to use and affordable Linux server for SMBs.
First-ever native Microsoft Active Directory® implementation on Linux that is easy to use. Zentyal Server incorporates all the network services required in a small and medium business environment: Directory & Domain Server, Mail Server, Gateway and Infrastructure Server.
Zentyal focuses primarly on improved Samba4 integration, with the goal of offering an easy-to-use Linux server that is natively compatible with the Microsoft® Active Directory.
Zentyal Server is based on Ubuntu Server and comes with the latest versions of all the integrated software. The single most important improvement Zentyal Server introduces is the integration of the latest Samba version (Samba 4.5.1) directly from upstream.
