2 Release Notes for Samba 3.2.0pre3
3 Mar 28, 2008
4 =================================
6 This is the third 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.
28 o Support for Vista clients authenticating via Kerberos.
30 Winbind and Active Directory Integration:
31 o Full support for Windows 2003 cross-forest, transitive trusts
32 and one-way domain trusts.
33 o Support for userPrincipalName logons via pam_winbind and NSS
34 lookups.
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).
39 Joining:
40 o New NetApi library for domain join related queries (libnetapi.so)
41 and example GTK+ Domain join gui.
42 o New client and server support for remotely joining and unjoining
43 Domains.
44 o Support for joining into Windows 2008 domains.
46 Users & Groups:
47 o New ldb backend for local group mapping tables
48 o Raised level of security defaults for authentication operations.
51 Documentation:
52 o Inclusion of an HTML version of the 3rd edition of "Using Samba"
53 from O'Reilly Publishing.
56 Now Licensed under the GNU GPLv3
57 ================================
59 The Samba Team has adopted the Version 3 of the GNU General Public
60 License for the 3.2 and later releases. The GPLv3 is the updated
61 version of the GPLv2 license under which Samba is currently
62 distributed. It has been updated to improve compatibility with other
63 licenses and to make it easier to adopt internationally, and is an
64 improved version of the license to better suit the needs of Free
65 Software in the 21st Century.
67 The original announcement is available on-line at
69 http://news.samba.org/announcements/samba_gplv3/
72 New Security Defaults for Authentication
73 ========================================
75 Support for LanMan passwords is now disabled in both client and server
76 applications. Additionally, clear text authentication requests are
77 disabled by default in client utilities such as smbclient and all
78 libsmbclient based applications. This will affect connection both
79 to and from hosts running DOS, Windows 9x/ME, and OS/2. Please refer
80 to the "Changes" section for details on the exact parameters that were
81 updated.
84 Registry Configuration Backend
85 ==============================
87 Samba is now able to use a registry based configuration backed to
88 supplement smb.conf setting. This feature may be enabled by setting
89 "config backend = registry" and "registry shares = yes" in the [global]
90 section of smb.conf and may be managed using the "net conf" command.
92 More information may be obtained from the smb.conf(5) and net(8) man
93 pages.
96 Removed Features
97 ================
99 Both the Python bindings and the libmsrpc shared library have been
100 removed from the tree due to lack of an official maintainer.
102 As smbfs is no longer supported in current kernel versions, smbmount has
103 been removed in this Samba version. Please use cifs (mount.cifs) instead.
104 See examples/scripts/mount/mount.smbfs as an example for a wrapper which
105 calls mount.cifs instead of smbmount/mount.smbfs.
108 Modified API for libsmbclient
109 ==============================================================================
111 Maintaining ABI compatibility for libsmbclient has become increasingly
112 difficult to accomplish, while also keeping the code organization such that it
113 is easily readable. Towards the goal of maintaining ABI compatibility and
114 also keeping the code easy to maintain and enhance, the API has been enhanced.
115 In particular, the fields in the SMBCCTX context structure are no longer
116 intended to be read/write by the user, and are marked as deprecated. An
117 application that previously accessed the members of the SMBCCTX context
118 structure will now encounter warnings if recompiled. This is intentional, to
119 encourage implementation of the small changes required for the new interface.
120 The number of changes is expected to be quite small for the vast majority of
121 applications, and no changes need be made for many applications. The changes
122 required for KDE (konqueror) to conform to the new interface, for example, are
123 only four lines in only one file.
125 Instead of the application manually changing or reading values in the context
126 structure, there are now setter and getter functions for each configurable
127 member in that structure. Similarly, the smbc_option_get() and
128 smbc_option_set() functions are deprecated in favor of the setter/getter
129 interface. The setters and getters are all documented in libsmbclient.h
130 under these comment blocks:
132 Getters and setters for CONFIGURATION
133 Getters and setters for OPTIONS
134 Getters and setters for FUNCTIONS
135 Callable functions for files
136 Callable functions for directories
137 Callable functions applicable to both files and directories
139 Example changes that may be required to eliminate "deprecated" warnings:
141 /* Set the debug level */
142 context->debug = 99;
143 changes to:
144 smbc_setDebug(context, 99);
146 /* Specify the authentication callback function */
147 context->callbacks.auth_fn = auth_smbc_get_data;
148 changes to:
149 smbc_setFunctionAuthData(context, auth_smbc_get_data);
151 /* Specify the new-style authentication callback with context parameter */
152 smbc_option_set("auth_function", auth_smbc_get_data_with_ctx);
153 changes to:
154 smbc_setFunctionAuthDataWithContext(context, auth_smbc_get_data_with_ctx);
156 /* Set kerberos flags */
157 context->flags = (SMB_CTX_FLAG_USE_KERBEROS |
158 SMB_CTX_FLAG_FALLBACK_AFTER_KERBEROS);
159 changes to:
160 smbc_setOptionUseKerberos(context, 1);
161 smbc_setOptionFallbackAfterKerberos(context, 1);
