Samba is the standard Windows interoperability suite of programs for Linux and Unix.
Samba is Free Software licensed under the GNU General Public License, the Samba project is a member of the Software Freedom Conservancy.
Since 1992, Samba has provided secure, stable and fast file and print services for all clients using the SMB/CIFS protocol, such as all versions of DOS and Windows, OS/2, Linux and many others.

The First Free Software Active Directory Compatible Server

Samba is an important component to seamlessly integrate Linux/Unix Servers and Desktops into Active Directory environments using the winbind daemon.
Samba 4.0 ships with an
LDAP directory server, Heimdal Kerberos authentication server, a secure Dynamic DNS server, and implementations of all necessary remote procedure calls for Active Directory. Samba 4.0 provides everything needed to serve as an Active Directory Compatible Domain Controller for all versions of Microsoft Windows clients currently supported by Microsoft, including the recently released Windows 8.

Aside from the usual stability, security and performance fixes, other highlights of this release are:
  • Support for SMB2.1 file serving
  • Support for integrated clustered file serving
  • Easy integration into existing Directory Services
Since Samba 4.0 was just released today, it is not likely that it has hit your distribution’s repository, but the beta version should be already there. You may read the release notes here. Official Samba documentations are available here.
