3 Feb 29, 2008
4 =================================
6 This is the second preview release of Samba 3.2.0. This is *not*
7 intended for production environments and is designed for testing
8 purposes only. Please report any defects via the Samba bug reporting
9 system at https://bugzilla.samba.org/.
11 Please be aware that Samba is now distributed under the version 3
12 of the new GNU General Public License. You may refer to the COPYING
13 file that accompanies these release notes for further licensing details.
15 Major enhancements in Samba 3.2.0 include:
17 File Serving:
18 o Use of IDL generated parsing layer for several DCE/RPC
19 interfaces.
20 o Removal of the 1024 byte limit on pathnames and 256 byte limit on
21 filename components to honor the MAX_PATH setting from the host OS.
22 o Introduction of a registry based configuration system.
23 o Improved CIFS Unix Extensions support.
24 o Experimental support for file serving clusters.
25 o Support for IPv6 in the server, and client tools and libraries.
26 o Support for storing alternate data streams in xattrs.
27 o Encrypted SMB transport in client tools and libraries, and server.
29 Winbind and Active Directory Integration:
30 o Full support for Windows 2003 cross-forest, transitive trusts
31 and one-way domain trusts.
32 o Support for userPrincipalName logons via pam_winbind and NSS
33 lookups.
34 o Support in pam_winbind for logging on using the userPrincipalName.
35 o Expansion of nested domain groups via NSS calls.
36 o Support for Active Directory LDAP Signing policy.
37 o New LGPL Winbind client library (libwbclient.so).
40 Users & Groups:
41 o New ldb backend for local group mapping tables
42 o Raised level of security defaults for authentication operations.
45 Documentation:
46 o Inclusion of an HTLM version of the 3rd edition of "Using Samba"
47 from O'Reilly Publishing.
50 Now Licensed under the GNU GPLv3
51 ================================
53 The Samba Team has adopted the Version 3 of the GNU General Public
54 License for the 3.2 and later releases. The GPLv3 is the updated
55 version of the GPLv2 license under which Samba is currently
56 distributed. It has been updated to improve compatibility with other
57 licenses and to make it easier to adopt internationally, and is an
58 improved version of the license to better suit the needs of Free
59 Software in the 21st Century.
61 The original announcement is available on-line at
63 http://news.samba.org/announcements/samba_gplv3/
66 New Security Defaults for Authentication
67 ========================================
69 Support for LanMan passwords is now disabled in both client and server
70 applications. Additionally, clear text authentication requests are
71 disabled by default in client utilities such as smbclient and all
72 libsmbclient based applications. This will affect connection both
73 to and from hosts running DOS, Windows 9x/ME, and OS/2. Please refer
74 to the "Changes" section for details on the exact parameters that were
75 updated.
79 Registry Configuration Backend
80 ==============================
82 Samba is now able to use a registry based configuration backed to
83 supplement smb.conf setting. This feature may be enabled by setting
84 "config backend = registry" and "registry shares = yes" in the [global]
85 section of smb.conf and may be managed using the "net conf" command.
87 More information may be obtained from the smb.conf(5) and net(8) man
88 pages.
91 Removed Features
92 ================
94 Both the Python bindings and the libmsrpc shared library have been
95 removed from the tree due to lack of an official maintainer.
