|

12 | <para>
|
---|
13 | This chapter provides a detailed record of changes made during the 3.x series releases. At this time this
|
---|
14 | series consists of the 3.0.x series that is under the GNU GPL version 2 license, and the Samba 3.2.x series
|
---|
15 | that is being released under the terms of the GNU GPL version 3 license.

|
---|
20 | <para>
|
---|
21 | Samba is a fluid product in which there may be significant changes between releases. Some of these changes are
|
---|
22 | brought about as a result of changes in the protocols that are used by Microsoft Windows network clients as a
|
---|
23 | result of security or functionality updates through official Microsoft patches and updates. Samba must track
|
---|
24 | such changes, particularly where they affect the internal operation of Samba itself.
|
---|
25 | </para>
|
---|
26 |
|
---|
27 | <para>
|
---|
28 | Please refer to any notes below that make explicit mention of the version of Samba you are using. In general,
|
---|
29 | all changes that apply to a new release will apply to follow-on releases also. For example, changes to Samba
|
---|
30 | 3.0.23 affect all releases up to an including 3.0.25 and later. Samba 3.2.x was originaly cut from Samba
|
---|
31 | 3.0.25 before 3.2.0-specific changes were applied. Unless a 3.0.x series feature is specifically revoked, the
|
---|
32 | behavior of the 3.2.x series can be expected to follow the earlier pattern.

47 | This chapter deals exclusively with the differences between Samba-3.0.25 and Samba-2.2.8a.
|
---|
48 | It points out where configuration parameters have changed, and provides a simple guide for
|
---|
49 | the move from 2.2.x to 3.0.25.

|
---|
56 | <para>
|
---|
57 | Samba-3.0.25 default behavior should be approximately the same as Samba-2.2.x.
|
---|
58 | The default behavior when the new parameter <smbconfoption name="passdb backend"/>
|
---|
59 | is not defined in the &smb.conf; file provides the same default behavior as Samba-2.2.x
|
---|
60 | with <smbconfoption name="encrypt passwords">Yes</smbconfoption> and
|
---|
61 | will use the <filename>smbpasswd</filename> database.

65 | <indexterm><primary>behavior approximately same</primary></indexterm>
|
---|
66 | <indexterm><primary>differing protocol</primary></indexterm>
|
---|
67 | So why say that <emphasis>behavior should be approximately the same as Samba-2.2.x</emphasis>? Because
|
---|
68 | Samba-3.0.25 can negotiate new protocols, such as support for native Unicode, that may result in
|
---|
69 | differing protocol code paths being taken. The new behavior under such circumstances is not
|
---|
70 | exactly the same as the old one. The good news is that the domain and machine SIDs will be
|
---|
71 | preserved across the upgrade.

|

79 | If the Samba-2.2.x system is using an LDAP backend, and there is no time to update the LDAP
|
---|
80 | database, then make sure that <smbconfoption name="passdb backend">ldapsam_compat</smbconfoption>
|
---|
81 | is specified in the &smb.conf; file. For the rest, behavior should remain more or less the same.
|
---|
82 | At a later date, when there is time to implement a new Samba-3-compatible LDAP backend, it is possible
|
---|
83 | to migrate the old LDAP database to the new one through use of the <command>pdbedit</command>.

618 | When operating as a member of a Windows domain, Samba-2.2 would map any users authenticated by the remote DC
|
---|
619 | to the <quote>guest account</quote> if a UID could not be obtained via the getpwnam() call. Samba-3 rejects
|
---|
620 | the connection with the error message <quote>NT_STATUS_LOGON_FAILURE.</quote> There is no current workaround
|
---|
621 | to re-establish the Samba-2.2 behavior.

|

627 | When adding machines to a Samba-2.2 controlled domain, the
|
---|
628 | <quote>add user script</quote> was used to create the UNIX identity of the
|
---|
629 | machine trust account. Samba-3 introduces a new <quote>add machine
|
---|
630 | script</quote> that must be specified for this purpose. Samba-3 will
|
---|
631 | not fall back to using the <quote>add user script</quote> in the absence of
|
---|
632 | an <quote>add machine script</quote>.

669 | the &smb.conf; man page and <link linkend="passdb">Account Information Databases</link>, for

670 | details. While both parameters assume sane default values, it is likely that you will need to understand what

671 | the values actually mean in order to ensure Samba operates correctly.

700 | A new object class (sambaSamAccount) has been introduced to replace
|
---|
701 | the old sambaAccount. This change aids in the renaming of attributes
|
---|
702 | to prevent clashes with attributes from other vendors. There is a
|
---|
703 | conversion script (examples/LDAP/convertSambaAccount) to modify an LDIF
|
---|
704 | file to the new schema.

|

741 | associated attributes have been moved to the historical section of
|
---|
742 | the schema file and must be uncommented before use if needed.
|

743 | The Samba-2.2 object class declaration for a <literal>sambaAccount</literal> has not changed

842 | Samba-3 supports an LDAP backend for the idmap subsystem. The

843 | following options inform Samba that the idmap table should be

844 | stored on the directory server <emphasis>onterose</emphasis> in the ou=Idmap,dc=quenya,dc=org partition.
