4 This is the first preview release of Samba 4.8. 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 4.8 will be the next version of the Samba suite.
22 Adds Group Policy support for the samba kdc. Applies password policies
23 (minimum/maximum password age, minimum password length, and password
24 complexity) and kerberos policies (user/service ticket lifetime and
27 Adds the samba_gpoupdate script for applying and unapplying
28 policy. Can be applied automatically by setting
30 'server services = +gpoupdate'.
32 Time Machine Support with vfs_fruit
33 ===================================
34 Samba can be configured as a Time Machine target for Apple Mac devices
35 through the vfs_fruit module. When enabling a share for Time Machine
36 support the relevant Avahi records to support discovery will be published
37 for installations that have been built against the Avahi client library.
39 Shares can be designated as a Time Machine share with the following setting:
41 'fruit:time machine = yes'
43 Support for lower casing the MDNS Name
44 ======================================
45 Allows the server name that is advertised through MDNS to be set to the
46 hostname rather than the Samba NETBIOS name. This allows an administrator
47 to make Samba registered MDNS records match the case of the hostname
48 rather than being in all capitals.
50 This can be set with the following settings:
56 Attributes deemed to be sensitive are now encrypted on disk. The sensitive
59 msDS-ExecuteScriptPassword
67 supplementalCredentials
73 This encryption is enabled by default on a new provision or join, it
74 can be disabled at provision or join time with the new option
77 However, an in-place upgrade will not encrypt the database.
79 Once encrypted, it is not possible to do an in-place downgrade (eg to
80 4.7) of the database. To obtain an unencrypted copy of the database a
81 new DC join should be performed, specifying the --plaintext-secrets
84 The key file "encrypted_secrets.key" is created in the same directory
85 as the database and should NEVER be disclosed. It is included by the
91 Parameter Name Description Default
92 -------------- ----------- -------
95 gpo update command New
96 map untrusted to domain Removed
97 oplock contention limit Removed
98 prefork children New 1
99 mdns name Added netbios
100 fruit:time machine Added false
103 winbind trusted domains only Removed
106 NT4-style replication based net commands removed
107 ================================================
109 The following commands and sub-commands have been removed from the
115 Also, replicating from a real NT4 domain with "net rpc vampire" and
116 "net rpc vampire keytab" has been removed.
118 The NT4-based commands were accidentially broken in 2013, and nobody
119 noticed the breakage. So instead of fixing them including tests (which
120 would have meant writing a server for the protocols, which we don't
121 have) we decided to remove them.
123 For the same reason, the "samsync", "samdeltas" and "database_redo"
124 commands have been removed from rpcclient.
126 "net rpc vampire keytab" from Active Directory domains continues to be
129 vfs_aio_linux module removed
130 ============================
132 The current Linux kernel aio does not match what Samba would
133 do. Shipping code that uses it leads people to false
134 assumptions. Samba implements async I/O based on threads by default,
135 there is no special module required to see benefits of read and write
136 request being sent do the disk in parallel.
138 smbclient reparse point symlink parameters reversed
139 ===================================================
141 A bug in smbclient caused the 'symlink' command to reverse the
142 meaning of the new name and link target parameters when creating a
143 reparse point symlink against a Windows server. As this is a
144 little used feature the ordering of these parameters has been
145 reversed to match the parameter ordering of the UNIX extensions
146 'symlink' command. The usage message for this command has also
147 been improved to remove confusion.
152 The two commands "net serverid list" and "net serverid wipe" have been
153 removed, because the file serverid.tdb is not used anymore.
155 "net serverid list" can be replaced by listing all files in the
156 subdirectory "msg.lock" of Samba's "lock directory". The unique id
157 listed by "net serverid list" is stored in every process' lockfile in
160 "net serverid wipe" is not necessary anymore. It was meant primarily
161 for clustered environments, where the serverid.tdb file was not
162 properly cleaned up after single node crashes. Nowadays smbd and
163 winbind take care of cleaning up the msg.lock and msg.sock directories
