Samba moved into 4.0 in December 2012 , Jeremey quotes We released Samba 4.0, containing the first compatible Free Software implementation of Microsoft's Active Directory protocols.

After the major release of 4.0.0 , Samba announced the security release 4.0.1 on January 2013.

Samba moved into 4.0 in December 2012 , Jeremey quotes We released Samba 4.0, containing the first compatible Free Software implementation of Microsoft's Active Directory protocols. 'Samba 4.0 comprises 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. The Samba 4.0 Active Directory Compatible Server provides support for features such as Group Policy, Roaming Profiles, Windows Administration tools and integrates with Microsoft
Exchange and Free Software compatible services such as   OpenChange.

As we know Samba is the most celebrated solution for networking non-Microsoft platforms (mostly Unix Platforms) with Windows machines. So what is so special about this release, well we have , here now the full compatibility suite for Microsofts active directory protocols, which says its revolutionary. This is a major step forward for the Samba team as well as the storage industry as a whole.

Most interesting feature, it also supports windows 8 on the fly, lets have the highlights here:

  • Support forNTVFS file server.
  • Support for two DNS solutions (a simple internal DNS server and a complex BIND plugin that uses the BIND DLZ mechanism).
  • Support for the Microsoft SMB 2.1 file serving protocol.
  • Experimental support for Microsoft SMB3 file serving protocol.
  • Support for Integrated Clustered File Server, through the clustered tdb"(ctdb) technology.
  • Improved winbind, now with support for easy integration with the MicrosoftActive Directory services.
  • Microsoft Exchange integration.
  • OpenChange integration.
  • NTP project integration for secured NTP replies.
  • Added a new Python scripting interface.

Its a major overhaul if we consider 3.x versions because it supports AD which is a mainstay of enterprise IT environments, and Microsoft is committed to support for interoperability across platforms. In an important addition, it also includes a modular "Virtual File System" (VFS) interface that vendors can use to quickly and efficiently customize Samba to take advantage of any specific features of their underlying technology without having to modify any of the core Samba code. From advanced file systems to network traffic analysis, the Samba VFS layer allows external code to be easily integrated with Samba. Example modules are provided as source code for vendors to customize as they wish.

Microsoft AD is the ONLY reason many companies (Apple shops included) have Microsoft servers. People cannot imagine how disruptive is a fully operational Samba 4.0 AD for Microsoft.

Its been great compliment for Opensource and Linux Community .It seems that Microsoft has finally learned that an ecosystem requires more than one player, and the storage and server teams at Microsoft should be commended for their embrace of competitors like Samba!
