4 This is the first release candidate of Samba 4.1. This is *not*
5 intended for production environments and is designed for testing
6 purposes only. Please report any defects via the Samba bug reporting
7 system at https://bugzilla.samba.org/.
9 Samba 4.1 will be the next version of the Samba suite and includes
10 all the technology found in both the Samba4 series and the stable 3.x
11 series. The primary additional features over Samba 3.6 are
12 support for the Active Directory logon protocols used by Windows 2000
15 If you are upgrading, or looking to develop, test or deploy Samba 4.1
16 releases candidates, you should backup all configuration and data.
22 Directory database replication (AD DC mode)
23 ===========================================
25 Directory replication has been reworked in order to improve the
26 correctness and efficiency.
27 As a net effect of it, replication with other domain controllers with
28 a heavily modified schema is now possible (ie. Windows 2012 DCs or
29 other Windows DC with exchange installed) and replication didn't fail
30 anymore in such environments.
33 Server-Side Copy Support
34 ========================
36 Samba 4.1.0 adds support for server-side copy operations via the SMB2
37 FSCTL_SRV_COPYCHUNK request. Clients making use of server-side copy
38 support, such as Windows Server 2012, should experience considerable
39 performance improvements for file copy operations, as file data need not
41 This feature is enabled by default on the smbd file server.
44 Btrfs Filesystem Integration
45 ============================
47 The Btrfs VFS module provided with Samba 4.1.0 further improves the
48 performance of server-side copy operations on shares backed by a Btrfs
49 filesystem. It does so by allowing multiple files to share the same
50 on-disk extents, avoiding the unnecessary duplication of source and
51 destination file data during a server-side copy operation.
53 This feature can be explicitly enabled on smbd shares backed by a Btrfs
54 filesystem with the smb.conf parameter:
61 The Samba Web Administration Tool (SWAT) has been removed.
