[Samba] [Announce] Samba 4.1.0 Available for Download
=================================================================
"Insanity: doing the same thing
over and over again and expecting
different results."

Release Announcements
---------------------
This is is the first stable release of Samba 4.1.
Samba 4.1 will be the next version of the Samba suite and includes
all the technology found in both the Samba4 series and the stable 3.x
series. The primary additional features over Samba 3.6 are
support for the Active Directory logon protocols used by Windows 2000
and above.
Major enhancements in Samba 4.1.0 include:
Client tools support SMB2/3
==========================
Samba 4.1.0 contains the first release of our client tools
and client library that work over the new protocols SMB2 or SMB3.
Note that SMB3 only works either to a Samba server version 4.0.0
or above, or to a Windows Server running Windows 2012 or Windows 8.
The default protocol for smbclient and smbcacls is still
SMB1 (the NT1 protocol dialect). An SMB2 or SMB3 connection
can be selected in one of two ways. The easiest way to test
the new protocol connection is to add the -mMAX_PROTOCOL
command line switch to either smbclient or smbcacls.
For example, to connect using SMB3 with smbclient a user
would type:
smbclient //server/share -Uuser%password -mSMB3
Another example of connecting using SMB2 using smbcacls
would be:
smbcacls //server/share -Uuser%password -mSMB2 filename
Note that when connecting using SMB2 or SMB3 protocols
the UNIX extensions are no longer available inside the
smbclient command set. This is due to UNIX extensions
not yet being defined for the SMB2 or SMB3 protocols.
The second way to select SMB2 or SMB3 connections is to
set the "client max protocol" parameter in the [global]
section of your smb.conf.
Setting this parameter will cause all client connections
from Samba and its client tools to offer the requested
max protocol to a server on every connection request.
For example, to cause all client tools (including winbindd,
rpcclient, and the libsmbclient library) to attempt use SMB3
by default add the line:
client max protocol = SMB3
to the [global] section of your smb.conf. This has not
been as widely tested as the -mPROTOCOL options, but
is intended to work correctly in the final release of
4.1.0.
Encrypted transport
==================
Although Samba servers have supported encrypted transport
connections using the UNIX extensions for many years,
selecting SMB3 transport allows encrypted transport
connections to Windows servers that support SMB3, as
well as Samba servers.
In order to enable this, add the "-e" option to the
smbclient command line.
For example, to connect to a Windows 2012 server over
SMB3 and select an encrypted transport you would use
the following command line:
smbclient //Win2012Server/share -Uuser%password -mSMB3 -e
Directory database replication (AD DC mode)
==========================================
Directory replication has been reworked in order to improve the
correctness and efficiency.
As a net effect of it, replication with other domain controllers with
a heavily modified schema is now possible (ie. Windows 2012 DCs or
other Windows DC with exchange installed) and replication didn't fail
anymore in such environments.
Server-Side Copy Support
=======================
Samba 4.1.0 adds support for server-side copy operations via the SMB2
FSCTL_SRV_COPYCHUNK request. Clients making use of server-side copy
support, such as Windows Server 2012, should experience considerable
performance improvements for file copy operations, as file data need not
traverse the network.
This feature is enabled by default on the smbd file server.
Btrfs Filesystem Integration
===========================
The Btrfs VFS module provided with Samba 4.1.0 further improves the
performance of server-side copy operations on shares backed by a Btrfs
filesystem. It does so by allowing multiple files to share the same
on-disk extents, avoiding the unnecessary duplication of source and
destination file data during a server-side copy operation.
This feature can be explicitly enabled on smbd shares backed by a Btrfs
filesystem with the smb.conf parameter:
vfs objects = btrfs
REMOVED COMPONENTS
=================
The Samba Web Administration Tool (SWAT) has been removed.
Details why SWAT has been removed can be found on the samba-technical mailing
list:
