4 This is the first preview release of Samba 4.10. This is *not*
5 intended for production environments and is designed for testing
6 purposes only. Please report any defects via the Samba bug reporting
7 system at https://bugzilla.samba.org/.
9 Samba 4.10 will be the next version of the Samba suite.
22 A new 'samba-tool gpo export' command has been added that can export a
23 set of Group Policy Objects from a domain in a generalised XML format.
25 A corresponding 'samba-tool gpo restore' command has been added to
26 rebuild the Group Policy Objects from the XML after generalization.
27 (The administrator needs to correct the values of XML entities between
28 the backup and restore to account for the change in domain).
33 The KDC now supports the pre-fork process model and worker processes will be
34 forked for the KDC when the pre-fork process model is selected for samba.
36 prefork 'prefork children'
37 --------------------------
39 The default value for this smdb.conf parameter has been increased from 1 to
45 DCERPC now supports pre-forked NETLOGON processes. The netlogon processes are
46 pre-forked when the prefork process model is selected for samba.
48 Offline domain backups
49 ----------------------
51 The 'samba-tool domain backup' command has been extended with a new 'offline'
52 option. This safely creates a backup of the local DC's database directly from
53 disk. The main benefits of an offline backup are it's quicker, it stores more
54 database details (for forensic purposes), and the samba process does not have
55 to be running when the backup is made. Refer to the samba-tool help for more
56 details on using this command.
58 Group membership statistics
59 ---------------------------
61 A new 'samba-tool group stats' command has been added. This provides summary
62 information about how the users are spread across groups in your domain.
63 The 'samba-tool group list --verbose' command has also been updated to include
64 the number of users in each group.
66 prefork process restart
67 -----------------------
69 The pre-fork process model now restarts failed processes. The delay between
70 restart attempts is controlled by the "prefork backoff increment" (default = 10)
71 and "prefork maximum backoff" (default = 120) smbd.conf parameters. A linear
72 back off strategy is used with "prefork backoff increment" added to the
73 delay between restart attempts up until it reaches "prefork maximum backoff".
75 Using the default sequence the restart delays (in seconds) are:
76 0, 10, 20, ..., 120, 120, ...
78 standard process model
79 ----------------------
81 When using the standard process model samba forks a new process to handle ldap
82 and netlogon connections. Samba now honours the 'max smbd processes' smb.conf
83 parameter. The default value of 0, indicates there is no limit. The limit
84 is applied individually to netlogon and ldap. When the process limit is
85 exceeded Samba drops new connections immediately.
90 The version of python which is now the default for samba is python3.
91 'configure' & 'make' will execute using python3. It is possible to still
92 specify an additional python version with '--extra-python'
93 e.g. '--extra-python=/usr/bin/python2'. It should be noted that support for
94 this option will be deprecated in a future release.
96 What if I need to build with python2? To build with python2 you *must* set
97 the 'PYTHON' environent variable to override the python3 default for both
98 'configure' and 'make' steps.
100 'PYTHON=python2 ./configure.developer'
102 'PYTHON=python2 make'
104 Note: Support for python2 (with the exception of a build configured with
105 'PYTHON=python2 ./configure --disable-python' and built with
106 'PYTHON=python2 make' will be deprecated in the next release.
111 Authentication messages now contain the Windows Event Id "eventId" and logon
112 type "logonType". The supported event codes and logon types are:
114 4624 Successful logon
115 4625 Unsuccessful logon
122 The version number for Authentication messages is now 1.1, changed from 1.0
124 Password change messages now contain the Windows Event Id "eventId", the
125 supported event Id's are:
126 4723 Password changed
129 The version number for PasswordChange messages is now 1.1, changed from 1.0
131 Group membership change messages now contain the Windows Event Id "eventId",
132 the supported event Id's are:
133 4728 A member was added to a security enabled global group
134 4729 A member was removed from a security enabled global group
135 4732 A member was added to a security enabled local group
136 4733 A member was removed from a security enabled local group
137 4746 A member was added to a security disabled local group
138 4747 A member was removed from a security disabled local group
139 4751 A member was added to a security disabled global group
140 4752 A member was removed from a security disabled global group
141 4756 A member was added to a security enabled universal group
142 4757 A member was removed from a security enabled universal group
143 4761 A member was added to a security disabled universal group
144 4762 A member was removed from a security disabled universal group
147 The version number for GroupChange messages is now 1.1, changed from 1.0. Also
148 A GroupChange message is generated when a new user is created to log that the
149 user has been added to their primary group.
151 The leading "JSON <message type>:" and source file prefix of the JSON formatted
152 log entries has been removed to make the parsing of the JSON log messages
153 easier. JSON log entries now start with 2 spaces followed by an opening brace
162 MIT Kerberos build of the AD DC
163 -------------------------------
165 While not removed, the MIT Kerberos build of the Samba AD DC is still
166 considered experimental. Because Samba will not issue security
167 patches for this configuration, such builds now require the explicit
168 configure option: --with-experimental-mit-ad-dc
170 For further details see
171 https://wiki.samba.org/index.php/Running_a_Samba_AD_DC_with_MIT_Kerberos_KDC
176 The samba_backup script has been removed. This has now been replaced by the
177 'samba-tool domain backup offline' command.
182 Parameter Name Description Default
183 -------------- ----------- -------
184 prefork backoff increment Delay added to process restart 10 (seconds)
186 prefork maximum backoff Maximum delay for process between 120 (seconds)
187 process restart attempts

193 "smbd:max async dosmode"

195 sharemode" but for SMB getinfo
