+Major new features:
+</p><div class="orderedlist"><ol type="1"><li><p>
+ Active Directory support. This release is able to join a ADS realm
+ as a member server and authenticate users using LDAP/kerberos.
+ </p></li><li><p>
+ Unicode support. Samba will now negotiate UNICODE on the wire and
+ internally there is now a much better infrastructure for multi-byte
+ and UNICODE character sets.
+ </p></li><li><p>
+ New authentication system. The internal authentication system has
+ been almost completely rewritten. Most of the changes are internal,
+ but the new auth system is also very configurable.
+ </p></li><li><p>
+ New filename mangling system. The filename mangling system has been
+ completely rewritten. An internal database now stores mangling maps
+ persistently. This needs lots of testing.
+ </p></li><li><p>
+ New &quot;net&quot; command. A new &quot;net&quot; command has been added. It is
+ somewhat similar to the &quot;net&quot; command in windows. Eventually we
+ plan to replace a bunch of other utilities (such as smbpasswd)
+ with subcommands in &quot;net&quot;, at the moment only a few things are
+ implemented.
+ </p></li><li><p>
+ Samba now negotiates NT-style status32 codes on the wire. This
+ improves error handling a lot.
+ </p></li><li><p>
+ Better Windows 2000/XP/2003 printing support including publishing
+ printer attributes in active directory
+ </p></li><li><p>
+ New loadable RPC modules
+ </p></li><li><p>
+ New dual-daemon winbindd support (-B) for better performance
+ </p></li><li><p>
+ Support for migrating from a Windows NT 4.0 domain to a Samba
+ domain and maintaining user, group and domain SIDs
+ </p></li><li><p>
+ Support for establishing trust relationships with Windows NT 4.0
+ domain controllers
+ </p></li><li><p>
+ Initial support for a distributed Winbind architecture using
+ an LDAP directory for storing SID to uid/gid mappings
+ </p></li><li><p>
+ Major updates to the Samba documentation tree.
+ </p></li></ol></div><p>
+Plus lots of other improvements!

+ The following issues are known changes in behavior between Samba 2.2 and
+ Samba 3.0 that may affect certain installations of Samba.
+ </p><div class="orderedlist"><ol type="1"><li><p>
+ When operating as a member of a Windows domain, Samba 2.2 would
+ map any users authenticated by the remote DC to the 'guest account'

+ rejects the connection as NT_STATUS_LOGON_FAILURE. There is no
+ current work around to re-establish the 2.2 behavior.
+ </p></li><li><p>
+ When adding machines to a Samba 2.2 controlled domain, the
+ 'add user script' was used to create the UNIX identity of the
+ machine trust account. Samba 3.0 introduces a new 'add machine
+ script' that must be specified for this purpose. Samba 3.0 will
+ not fall back to using the 'add user script' in the absence of
+ an 'add machine script'

+ There have been a few new changes that Samba administrators should be
+ aware of when moving to Samba 3.0.
+ </p><div class="orderedlist"><ol type="1"><li><p>
+ Encrypted passwords have been enabled by default in order to
+ inter-operate better with out-of-the-box Windows client
+ installations. This does mean that either (a) a samba account
+ must be created for each user, or (b) 'encrypt passwords = no'
+ must be explicitly defined in smb.conf.
+ </p></li><li><p>
+ Inclusion of new <a class="indexterm" name="id2955194"></a><i class="parameter"><tt>security</tt></i> = ads option for integration
+ with an Active Directory domain using the native Windows
+ Kerberos 5 and LDAP protocols.
+ </p></li></ol></div><p>
+ Samba 3.0 also includes the possibility of setting up chains
+ of authentication methods
+ (<a class="indexterm" name="id2955217"></a><i class="parameter"><tt>auth methods</tt></i>) and account
+ storage backends
+ (<a class="indexterm" name="id2955232"></a><i class="parameter"><tt>passdb backend</tt></i>).
+ Please refer to the <tt class="filename">smb.conf</tt>
+ man page and <a href="passdb.html" title="Chapter 11. Account Information Databases">the chapter about account information databases</a> for details. While both parameters assume sane default
+ values, it is likely that you will need to understand what the
+ values actually mean in order to ensure Samba operates correctly.
+ </p><p>
+ Certain functions of the smbpasswd(8) tool have been split between the
+ new smbpasswd(8) utility, the net(8) tool, and the new pdbedit(8)
+ utility. See the respective man pages for details.

+ <a href="unicode.html" title="Chapter 27. Unicode/Charsets">Unicode support</a> for details.
+ </p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2955299"></a>LDAP</h3></div></div><div></div></div><p>
+ This section outlines the new features affecting Samba / LDAP integration.
+ </p><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id2955311"></a>New Schema</h4></div></div><div></div></div><p>
+ A new object class (sambaSamAccount) has been introduced to replace
+ the old sambaAccount. This change aids us in the renaming of attributes
+ to prevent clashes with attributes from other vendors. There is a
+ conversion script (examples/LDAP/convertSambaAccount) to modify and LDIF
+ file to the new schema.
+ </p><p>
+ Example:
+ </p><pre class="screen">
+ <tt class="prompt">$ </tt>ldapsearch .... -b &quot;ou=people,dc=...&quot; &gt; old.ldif
+ <tt class="prompt">$ </tt>convertSambaAccount &lt;DOM SID&gt; old.ldif new.ldif
+ </pre><p>
+ The &lt;DOM SID&gt; can be obtained by running 'net getlocalsid &lt;DOMAINNAME&gt;
+ on the Samba PDC as root.
+ </p><p>
+ The old sambaAccount schema may still be used by specifying the
+ &quot;ldapsam_compat&quot; passdb backend. However, the sambaAccount and
+ associated attributes have been moved to the historical section of
+ the schema file and must be uncommented before use if needed.
+ The 2.2 object class declaration for a sambaAccount has not changed
+ in the 3.0 samba.schema file.
+ </p><p>
+ Other new object classes and their uses include:
+ </p><div class="itemizedlist"><ul type="disc"><li><p>
+ sambaDomain - domain information used to allocate rids
+ for users and groups as necessary. The attributes are added
+ in 'ldap suffix' directory entry automatically if
+ an idmap uid/gid range has been set and the 'ldapsam'
+ passdb backend has been selected.
+ </p></li><li><p>
+ sambaGroupMapping - an object representing the
+ relationship between a posixGroup and a Windows
+ group/SID. These entries are stored in the 'ldap
+ group suffix' and managed by the 'net groupmap' command.
+ </p></li><li><p>
+ sambaUnixIdPool - created in the 'ldap idmap suffix' entry
+ automatically and contains the next available 'idmap uid' and
+ 'idmap gid'
+ </p></li><li><p>
+ sambaIdmapEntry - object storing a mapping between a
+ SID and a UNIX uid/gid. These objects are created by the
+ idmap_ldap module as needed.
+ </p></li></ul></div></div><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id2955433"></a>New Suffix for Searching</h4></div></div><div></div></div><p>
+ The following new smb.conf parameters have been added to aid in directing
+ certain LDAP queries when 'passdb backend = ldapsam://...' has been
+ specified.
+ </p><div class="itemizedlist"><ul type="disc"><li><p>ldap suffix - used to search for user and computer accounts</p></li><li><p>ldap user suffix - used to store user accounts</p></li><li><p>ldap machine suffix - used to store machine trust accounts</p></li><li><p>ldap group suffix - location of posixGroup/sambaGroupMapping entries</p></li><li><p>ldap idmap suffix - location of sambaIdmapEntry objects</p></li></ul></div><p>
+ If an 'ldap suffix' is defined, it will be appended to all of the
+ remaining sub-suffix parameters. In this case, the order of the suffix
+ listings in smb.conf is important. Always place the 'ldap suffix' first
+ in the list.
+ </p><p>
+ Due to a limitation in Samba's smb.conf parsing, you should not surround
+ the DN's with quotation marks.

+ Samba 3.0 supports an ldap backend for the idmap subsystem. The
+ following options would inform Samba that the idmap table should be
+ stored on the directory server onterose in the &quot;ou=idmap,dc=plainjoe,
+ dc=org&quot; partition.
+ </p><table class="simplelist" border="0" summary="Simple list"><tr><td> </td></tr><tr><td><i class="parameter"><tt>[global]</tt></i></td></tr><tr><td>...</td></tr><tr><td><i class="parameter"><tt>idmap backend = ldap:ldap://onterose/</tt></i></td></tr><tr><td><i class="parameter"><tt>ldap idmap suffix = ou=idmap,dc=plainjoe,dc=org</tt></i></td></tr><tr><td><i class="parameter"><tt>idmap uid = 40000-50000</tt></i></td></tr><tr><td><i class="parameter"><tt>idmap gid = 40000-50000</tt></i></td></tr></table><p>
+ This configuration allows winbind installations on multiple servers to
+ share a uid/gid number space, thus avoiding the interoperability problems
+ with NFS that were present in Samba 2.2.
