    Release Announcements
    =====================

    This is the third preview release of Samba 3.2.0. This is *not*
    intended for production environments and is designed for testing
    purposes only. Please report any defects via the Samba bug reporting
    system at https://bugzilla.samba.org/.

    Please be aware that Samba is now distributed under the version 3
    of the new GNU General Public License. You may refer to the COPYING
    file that accompanies these release notes for further licensing details.

    Major enhancements in Samba 3.2.0 include:

    File Serving:
    o Use of IDL generated parsing layer for several DCE/RPC
    interfaces.
    o Removal of the 1024 byte limit on pathnames and 256 byte limit on
    filename components to honor the MAX_PATH setting from the host OS.
    o Introduction of a registry based configuration system.
    o Improved CIFS Unix Extensions support.
    o Experimental support for file serving clusters.
    o Support for IPv6 in the server, and client tools and libraries.
    o Support for storing alternate data streams in xattrs.
    o Encrypted SMB transport in client tools and libraries, and server.
    o Support for Vista clients authenticating via Kerberos.

    Winbind and Active Directory Integration:
    o Full support for Windows 2003 cross-forest, transitive trusts
    and one-way domain trusts.
    o Support for userPrincipalName logons via pam_winbind and NSS
    lookups.
    o Expansion of nested domain groups via NSS calls.
    o Support for Active Directory LDAP Signing policy.
    o New LGPL Winbind client library (libwbclient.so).

    Joining:
    o New NetApi library for domain join related queries (libnetapi.so)
    and example GTK+ Domain join gui.
    o New client and server support for remotely joining and unjoining
    Domains.
    o Support for joining into Windows 2008 domains.

    Users & Groups:
    o New ldb backend for local group mapping tables
    o Raised level of security defaults for authentication operations.


    Documentation:
    o Inclusion of an HTML version of the 3rd edition of "Using Samba"
    from O'Reilly Publishing.


    Now Licensed under the GNU GPLv3
    ================================

    The Samba Team has adopted the Version 3 of the GNU General Public
    License for the 3.2 and later releases. The GPLv3 is the updated
    version of the GPLv2 license under which Samba is currently
    distributed. It has been updated to improve compatibility with other
    licenses and to make it easier to adopt internationally, and is an
    improved version of the license to better suit the needs of Free
    Software in the 21st Century.

    The original announcement is available on-line at

    http://news.samba.org/announcements/samba_gplv3/


    New Security Defaults for Authentication
    ========================================

    Support for LanMan passwords is now disabled in both client and server
    applications. Additionally, clear text authentication requests are
    disabled by default in client utilities such as smbclient and all
    libsmbclient based applications. This will affect connection both
    to and from hosts running DOS, Windows 9x/ME, and OS/2. Please refer
    to the "Changes" section for details on the exact parameters that were
    updated.


    Registry Configuration Backend
    ==============================

    Samba is now able to use a registry based configuration backed to
    supplement smb.conf settings. This feature may be enabled by setting
    "config backend = registry" in the [global] section of smb.conf for a
    registry only configuration, or by specifying "include = registry" to
    include global options from registry for a mixed setup.

    The new parameter "registry shares = yes" in the [global] section of
    smb.conf can be used to activate share definitions from registry.
    These shares are loaded on demand by the server. Registry shares are
    automatically activated by the global registry options above.

    The configuration stored in registry can be conveniently managed using
    the "net conf" command.

    More information may be obtained from the smb.conf(5) and net(8) man
    pages.


    Removed Features
    ================

    Both the Python bindings and the libmsrpc shared library have been
    removed from the tree due to lack of an official maintainer.

    As smbfs is no longer supported in current kernel versions, smbmount has
    been removed in this Samba version. Please use cifs (mount.cifs) instead.
    See examples/scripts/mount/mount.smbfs as an example for a wrapper which
    calls mount.cifs instead of smbmount/mount.smbfs.


    Modified API for libsmbclient
    ================================================== ============================

    Maintaining ABI compatibility for libsmbclient has become increasingly
    difficult to accomplish, while also keeping the code organization such that it
    is easily readable. Towards the goal of maintaining ABI compatibility and
    also keeping the code easy to maintain and enhance, the API has been enhanced.
    In particular, the fields in the SMBCCTX context structure are no longer
    intended to be read/write by the user, and are marked as deprecated. An
    application that previously accessed the members of the SMBCCTX context
    structure will now encounter warnings if recompiled. This is intentional, to
    encourage implementation of the small changes required for the new interface.
    The number of changes is expected to be quite small for the vast majority of
    applications, and no changes need be made for many applications. The changes
    required for KDE (konqueror) to conform to the new interface, for example, are
    only four lines in only one file.

    Instead of the application manually changing or reading values in the context
    structure, there are now setter and getter functions for each configurable
    member in that structure. Similarly, the smbc_option_get() and
    smbc_option_set() functions are deprecated in favor of the setter/getter
    interface. The setters and getters are all documented in libsmbclient.h
    under these comment blocks:

    Getters and setters for CONFIGURATION
    Getters and setters for OPTIONS
    Getters and setters for FUNCTIONS
    Callable functions for files
    Callable functions for directories
    Callable functions applicable to both files and directories

    Example changes that may be required to eliminate "deprecated" warnings:

    /* Set the debug level */
    context->debug = 99;
    changes to:
    smbc_setDebug(context, 99);

    /* Specify the authentication callback function */
    context->callbacks.auth_fn = auth_smbc_get_data;
    changes to:
    smbc_setFunctionAuthData(context, auth_smbc_get_data);

    /* Specify the new-style authentication callback with context parameter */
    smbc_option_set("auth_function", auth_smbc_get_data_with_ctx);
    changes to:
    smbc_setFunctionAuthDataWithContext(context, auth_smbc_get_data_with_ctx);

    /* Set kerberos flags */
    context->flags = (SMB_CTX_FLAG_USE_KERBEROS |
    SMB_CTX_FLAG_FALLBACK_AFTER_KERBEROS);
    changes to:
    smbc_setOptionUseKerberos(context, 1);
    smbc_setOptionFallbackAfterKerberos(context, 1);

    Can someone explain that some more. Is that a tightening or loosing
    of the restriction?
    Or point me do a discussion about how it was decided to do this?

    === My concern
    IIRC MAX_PATH is 512 under Windows, but it is a lie that cannot be
    trusted. It is just the limit for the old API. The new Unicode APIs
    do not honor that define. I'm concerned this may be true of other
    filesystems / OSes.

    In particular with Robocopy that comes with Windows 2003 Resource Kit
    you can work with pathnames up to 32K I believe it is. (See the
    Robocopy release notes for details). A lot of tools are still
    restricted to 512 chars, but I am fairly confident that 512 is no
    longer a fundamental limitation with newer Windows products.

    This is a losening of the restriction. Incoming paths from clients
    can now be as long as the PATH_MAX of the system hosting Samba.

    > Or point me do a discussion about how it was decided to do this?


    Look back in Samba-technical for the comments from Volker and
    myself on restructuring to smb_request and removal of pstrings.

    We should now be able to work with any Windows pathname a client
    generates, no more 1024 byte restriction.

    It's simply a removal of static path buffers (char[1024])
    to dynamically allocated ones.
