Samba Team Releases Samba 4.0 

December 11th 2012. 

The Samba Team is proud to announce the release of Samba 4.0, a major 
new release of the award-winning Free Software file, print and 
authentication server suite for Microsoft Windows clients. 

The First Free Software Active Directory Compatible Server 

As the culmination of ten years' work, the Samba Team has created the 
first compatible Free Software implementation of Microsoft’s Active 
Directory protocols. Familiar to all network administrators, the 
Active Directory protocols are the heart of modern directory service 

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. 

The Samba 4.0 Active Directory Compatible Server can also be joined to 
an existing Microsoft Active Directory domain, and Microsoft Active 
Directory Domain Controllers can be joined to a Samba 4.0 Active 
Directory Compatible Server, showing true peer-to-peer 
interoperability of the Microsoft and Samba implementations of the 
Active Directory protocols. 

Acknowledging the value of the interoperability of the Samba 4.0 
Active Directory Compatible Server, Steve van Maanen, the co-founder 
of Starsphere LLC, an IT services company in Tokyo, said: 

"Thanks to Samba4, I have two fully replicating Active Directory 
Domain controllers that boot in under 10 seconds ! It is nice to have 
alternatives, and Samba4 is a great one." 

Upgrade scripts are also provided for organizations using the previous 
Microsoft Windows NT Domain Controller functionality in Samba 3.x, to 
allow them to migrate smoothly to Samba 4.0. 

Suitable for low-power and embedded applications, yet scaling to large 
clusters, Samba 4.0 is efficient and flexible. Its Python programming 
interface and administration toolkit help in enterprise deployments. 

Created Using Microsoft Documentation 

The Samba 4.0 Active Directory Compatible Server was created with help 
from the official protocol documentation published by Microsoft 
Corporation and the Samba Team would like acknowledge the 
documentation help and interoperability testing by Microsoft engineers 
that made our implementation interoperable. 

"Active Directory is a mainstay of enterprise IT environments, and 
Microsoft is committed to support for interoperability across 
platforms," said Thomas Pfenning, director of development, Windows 
Server. "We are pleased that the documentation and interoperability 
labs that Microsoft has provided have been key in the development of 
the Samba 4.0 Active Directory functionality." 

Introducing SMB2.1 File Serving Support 

Samba 4.0 includes the first Free Software implementation of 
Microsoft's SMB2.1 file serving protocol. Building on the success of 
the SMB2.0 server in Samba 3.6, the Samba 4.0 file server component is 
an evolution of the trusted Samba file serving code that is used 
worldwide by vendors of file servers, such as IBM's clustered Scale 
Out Network Attached Storage (SONAS), and many other commercial 

In addition, the Samba 4.0 file server contains an initial 
implementation of SMB3, which will be further developed in later Samba 
4 releases into a fully-featured SMB3 clustered file server 

Future developments of our SMB3 server and client suite, in 
combination with our expanding number of SMB3 tests, will keep driving 
the performance improvements and improved compatibility with Microsoft 
Windows that Samba users have come to expect from our software. 

Integrated Clustered File Server Support 

Building on our success as the first commercial implementation of a 
clustered SMB/CIFS server, Samba 4.0 provides industry-leading 
scalability and performance as a clustered SMB2/SMB/CIFS file server, 
using our "clustered tdb" (ctdb) technology - also available as Free 

Clustered Samba provides a "Single Server" view of clustered file 
storage, allowing clients to connect to the least loaded server and 
still providing a completely coherent view of the underlying clustered 
file system. 

Written and tested to be compatible with most clustered file systems, 
both Free Software and proprietary, Samba 4.0 with ctdb provides a 
scalable clustered file server solution with full Windows file sharing 

Samba and ctdb have been shipping in production file serving products 
for many years, to some of the most demanding customers in the world. 

Easy Integration into Existing Directory Services 

Samba 4.0 ships with an improved winbind, which allows Samba 4.0 file 
servers to easily integrate into existing Active Directory services as 
member servers. Both Microsoft Active Directory and Samba 4.0 Active 
Directory Compatible servers are supported. 

Stability, Security and Performance 

Samba 4.0 has been tested using our widely accepted smbtorture test 
suite, created by the Samba Team to test Samba itself and now used by 
most of the companies writing SMB3/SMB2/SMB/CIFS file server software 
to test their own products. We also regularly test interoperability 
with other major vendors at plug-fest events to make sure Samba 4.0 
deployments work correctly with existing customer equipment. 

In addition, Samba is one of eleven open source projects that leading 
software integrity vendor Coverity has certified as "secure" and has 
reached Coverity "Integrity Rung 2" certification. 

The Samba Team provides immediate responses to any security 
vulnerabilities, and provides fixes to all vendors using the Samba 
code in coordination with industry standard security reporting 

A Modular Toolbox for OEM Vendor Needs 

As Free Software, Samba 4.0 is the ideal choice for Original Equipment 
Manufacturers (OEMs) to use for their file, print and authentication 
products. It is easily integrated into a whole host of different 
tasks, and can be customized at will by the vendor to satisfy their 

In addition, Samba 4.0 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 

Samba is the leading choice for Microsoft Windows connectivity 

Samba is the leading technology choice for Windows file serving on 
Linux and UNIX platforms and in embedded Network Attached Storage 
(NAS) solutions. Samba is used by vendors selling NAS solutions 
ranging from high end clustered business-critical systems, to low end 
consumer devices, and everything in between. Samba is fully IPv6 
enabled and meets all mandates for modern network interoperability. 

Commercial support is available for Samba from many different vendors. 

Getting Samba 4.0 

Samba 4.0 source code is available now from the Samba Web site.
