2 Release Notes for Samba 4.2.10
4 ==============================
7 This is a security release in order to address the following CVEs:
9 o CVE-2015-5370 (Multiple errors in DCE-RPC code)
11 o CVE-2016-2110 (Man in the middle attacks possible with NTLMSSP)
13 o CVE-2016-2111 (NETLOGON Spoofing Vulnerability)
15 o CVE-2016-2112 (LDAP client and server don't enforce integrity)
17 o CVE-2016-2113 (Missing TLS certificate validation)
19 o CVE-2016-2114 ("server signing = mandatory" not enforced)
21 o CVE-2016-2115 (SMB IPC traffic is not integrity protected)
23 o CVE-2016-2118 (SAMR and LSA man in the middle attacks possible)
25 The number of changes are rather huge for a security release,
26 compared to typical security releases.
28 Given the number of problems and the fact that they are all related
29 to man in the middle attacks we decided to fix them all at once
30 instead of splitting them.
32 In order to prevent the man in the middle attacks it was required
33 to change the (default) behavior for some protocols. Please see the
34 "New smb.conf options" and "Behavior changes" sections below.
42 Versions of Samba from 3.6.0 to 4.4.0 inclusive are vulnerable to
43 denial of service attacks (crashes and high cpu consumption)
44 in the DCE-RPC client and server implementations. In addition,
45 errors in validation of the DCE-RPC packets can lead to a downgrade
46 of a secure connection to an insecure one.
48 The above applies all possible server roles Samba can operate in.
50 Note that versions before 3.6.0 had completely different marshalling
51 functions for the generic DCE-RPC layer. It's quite possible that
52 that code has similar problems!
54 The downgrade of a secure connection to an insecure one may
55 allow an attacker to take control of Active Directory object
56 handles created on a connection created from an Administrator
57 account and re-use them on the now non-privileged connection,
58 compromising the security of the Samba AD-DC.
62 There are several man in the middle attacks possible with
63 NTLMSSP authentication.
65 E.g. NTLMSSP_NEGOTIATE_SIGN and NTLMSSP_NEGOTIATE_SEAL
66 can be cleared by a man in the middle.
68 This was by protocol design in earlier Windows versions.
70 Windows Server 2003 RTM and Vista RTM introduced a way
71 to protect against the trivial downgrade.
73 See MsvAvFlags and flag 0x00000002 in
74 https://msdn.microsoft.com/en-us/library/cc236646.aspx
76 This new feature also implies support for a mechlistMIC
77 when used within SPNEGO, which may prevent downgrades
78 from other SPNEGO mechs, e.g. Kerberos, if sign or
79 seal is finally negotiated.
81 The Samba implementation doesn't enforce the existence of
82 required flags, which were requested by the application layer,
83 e.g. LDAP or SMB1 encryption (via the unix extensions).
84 As a result a man in the middle can take over the connection.
85 It is also possible to misguide client and/or
86 server to send unencrypted traffic even if encryption
87 was explicitly requested.
89 LDAP (with NTLMSSP authentication) is used as a client
90 by various admin tools of the Samba project,
91 e.g. "net", "samba-tool", "ldbsearch", "ldbedit", ...
93 As an active directory member server LDAP is also used
94 by the winbindd service when connecting to domain controllers.
96 Samba also offers an LDAP server when running as
97 active directory domain controller.
99 The NTLMSSP authentication used by the SMB1 encryption
100 is protected by smb signing, see CVE-2015-5296.
104 It's basically the same as CVE-2015-0005 for Windows:
106 The NETLOGON service in Microsoft Windows Server 2003 SP2,
107 Windows Server 2008 SP2 and R2 SP1, and Windows Server 2012 Gold
108 and R2, when a Domain Controller is configured, allows remote
109 attackers to spoof the computer name of a secure channel's
110 endpoint, and obtain sensitive session information, by running a
111 crafted application and leveraging the ability to sniff network
112 traffic, aka "NETLOGON Spoofing Vulnerability".
114 The vulnerability in Samba is worse as it doesn't require
115 credentials of a computer account in the domain.
117 This only applies to Samba running as classic primary domain controller,
118 classic backup domain controller or active directory domain controller.
120 The security patches introduce a new option called "raw NTLMv2 auth"
121 ("yes" or "no") for the [global] section in smb.conf.
122 Samba (the smbd process) will reject client using raw NTLMv2
123 without using NTLMSSP.
125 Note that this option also applies to Samba running as
126 standalone server and member server.
128 You should also consider using "lanman auth = no" (which is already the default)
129 and "ntlm auth = no". Have a look at the smb.conf manpage for further details,
130 as they might impact compatibility with older clients. These also
131 apply for all server roles.
135 Samba uses various LDAP client libraries, a builtin one and/or the system
136 ldap libraries (typically openldap).
138 As active directory domain controller Samba also provides an LDAP server.
140 Samba takes care of doing SASL (GSS-SPNEGO) authentication with Kerberos or NTLMSSP
141 for LDAP connections, including possible integrity (sign) and privacy (seal)
144 Samba has support for an option called "client ldap sasl wrapping" since version
145 3.2.0. Its default value has changed from "plain" to "sign" with version 4.2.0.
147 Tools using the builtin LDAP client library do not obey the
148 "client ldap sasl wrapping" option. This applies to tools like:
149 "samba-tool", "ldbsearch", "ldbedit" and more. Some of them have command line
150 options like "--sign" and "--encrypt". With the security update they will
151 also obey the "client ldap sasl wrapping" option as default.
153 In all cases, even if explicitly request via "client ldap sasl wrapping",
154 "--sign" or "--encrypt", the protection can be downgraded by a man in the
157 The LDAP server doesn't have an option to enforce strong authentication
158 yet. The security patches will introduce a new option called
159 "ldap server require strong auth", possible values are "no",
160 "allow_sasl_over_tls" and "yes".
162 As the default behavior was as "no" before, you may
163 have to explicitly change this option until all clients have
164 been adjusted to handle LDAP_STRONG_AUTH_REQUIRED errors.
165 Windows clients and Samba member servers already use
166 integrity protection.
170 Samba has support for TLS/SSL for some protocols:
171 ldap and http, but currently certificates are not
172 validated at all. While we have a "tls cafile" option,
173 the configured certificate is not used to validate
174 the server certificate.
176 This applies to ldaps:// connections triggered by tools like:
177 "ldbsearch", "ldbedit" and more. Note that it only applies
178 to the ldb tools when they are built as part of Samba or with Samba
179 extensions installed, which means the Samba builtin LDAP client library is
182 It also applies to dcerpc client connections using ncacn_http (with https://),
183 which are only used by the openchange project. Support for ncacn_http
184 was introduced in version 4.2.0.
186 The security patches will introduce a new option called
187 "tls verify peer". Possible values are "no_check", "ca_only",
188 "ca_and_name_if_available", "ca_and_name" and "as_strict_as_possible".
190 If you use the self-signed certificates which are auto-generated
191 by Samba, you won't have a crl file and need to explicitly
192 set "tls verify peer = ca_and_name".
196 Due to a regression introduced in Samba 4.0.0,
197 an explicit "server signing = mandatory" in the [global] section
198 of the smb.conf was not enforced for clients using the SMB1 protocol.
200 As a result it does not enforce smb signing and allows man in the middle attacks.
202 This problem applies to all possible server roles:
203 standalone server, member server, classic primary domain controller,
204 classic backup domain controller and active directory domain controller.
206 In addition, when Samba is configured with "server role = active directory domain controller"
207 the effective default for the "server signing" option should be "mandatory".
209 During the early development of Samba 4 we had a new experimental
210 file server located under source4/smb_server. But before
211 the final 4.0.0 release we switched back to the file server
214 But the logic for the correct default of "server signing" was not
215 ported correctly ported.
217 Note that the default for server roles other than active directory domain
218 controller, is "off" because of performance reasons.
222 Samba has an option called "client signing", this is turned off by default
223 for performance reasons on file transfers.
225 This option is also used when using DCERPC with ncacn_np.
227 In order to get integrity protection for ipc related communication
228 by default the "client ipc signing" option is introduced.
229 The effective default for this new option is "mandatory".
231 In order to be compatible with more SMB server implementations,
232 the following additional options are introduced:
233 "client ipc min protocol" ("NT1" by default) and
234 "client ipc max protocol" (the highest support SMB2/3 dialect by default).
235 These options overwrite the "client min protocol" and "client max protocol"
236 options, because the default for "client max protocol" is still "NT1".
237 The reason for this is the fact that all SMB2/3 support SMB signing,
238 while there are still SMB1 implementations which don't offer SMB signing
239 by default (this includes Samba versions before 4.0.0).
241 Note that winbindd (in versions 4.2.0 and higher) enforces SMB signing
242 against active directory domain controllers despite of the
243 "client signing" and "client ipc signing" options.
245 o CVE-2016-2118 (a.k.a. BADLOCK):
247 The Security Account Manager Remote Protocol [MS-SAMR] and the
248 Local Security Authority (Domain Policy) Remote Protocol [MS-LSAD]
249 are both vulnerable to man in the middle attacks. Both are application level
250 protocols based on the generic DCE 1.1 Remote Procedure Call (DCERPC) protocol.
252 These protocols are typically available on all Windows installations
253 as well as every Samba server. They are used to maintain
254 the Security Account Manager Database. This applies to all
255 roles, e.g. standalone, domain member, domain controller.
257 Any authenticated DCERPC connection a client initiates against a server
258 can be used by a man in the middle to impersonate the authenticated user
259 against the SAMR or LSAD service on the server.
261 The client chosen application protocol, auth type (e.g. Kerberos or NTLMSSP)
262 and auth level (NONE, CONNECT, PKT_INTEGRITY, PKT_PRIVACY) do not matter
263 in this case. A man in the middle can change auth level to CONNECT
264 (which means authentication without message protection) and take over
267 As a result, a man in the middle is able to get read/write access to the
268 Security Account Manager Database, which reveals all passwords
269 and any other potential sensitive information.
271 Samba running as an active directory domain controller is additionally
272 missing checks to enforce PKT_PRIVACY for the
273 Directory Replication Service Remote Protocol [MS-DRSR] (drsuapi)
274 and the BackupKey Remote Protocol [MS-BKRP] (backupkey).
275 The Domain Name Service Server Management Protocol [MS-DNSP] (dnsserver)
276 is not enforcing at least PKT_INTEGRITY.
282 allow dcerpc auth level connect (G)
284 This option controls whether DCERPC services are allowed to be used with
285 DCERPC_AUTH_LEVEL_CONNECT, which provides authentication, but no per
286 message integrity nor privacy protection.
288 Some interfaces like samr, lsarpc and netlogon have a hard-coded default
289 of no and epmapper, mgmt and rpcecho have a hard-coded default of yes.
291 The behavior can be overwritten per interface name (e.g. lsarpc,
292 netlogon, samr, srvsvc, winreg, wkssvc ...) by using
293 'allow dcerpc auth level connect:interface = yes' as option.
295 This option yields precedence to the implementation specific restrictions.
296 E.g. the drsuapi and backupkey protocols require DCERPC_AUTH_LEVEL_PRIVACY.
297 The dnsserver protocol requires DCERPC_AUTH_LEVEL_INTEGRITY.
299 Default: allow dcerpc auth level connect = no
301 Example: allow dcerpc auth level connect = yes
303 client ipc signing (G)
305 This controls whether the client is allowed or required to use
306 SMB signing for IPC$ connections as DCERPC transport. Possible
307 values are auto, mandatory and disabled.
309 When set to mandatory or default, SMB signing is required.
311 When set to auto, SMB signing is offered, but not enforced and
312 if set to disabled, SMB signing is not offered either.
314 Connections from winbindd to Active Directory Domain Controllers
315 always enforce signing.
317 Default: client ipc signing = default
319 client ipc max protocol (G)
321 The value of the parameter (a string) is the highest protocol level that will
322 be supported for IPC$ connections as DCERPC transport.
324 Normally this option should not be set as the automatic negotiation phase
325 in the SMB protocol takes care of choosing the appropriate protocol.
327 The value default refers to the latest supported protocol, currently SMB3_11.
329 See client max protocol for a full list of available protocols.
330 The values CORE, COREPLUS, LANMAN1, LANMAN2 are silently upgraded to NT1.
332 Default: client ipc max protocol = default
334 Example: client ipc max protocol = SMB2_10
336 client ipc min protocol (G)
338 This setting controls the minimum protocol version that the will be
339 attempted to use for IPC$ connections as DCERPC transport.
341 Normally this option should not be set as the automatic negotiation phase
342 in the SMB protocol takes care of choosing the appropriate protocol.
344 The value default refers to the higher value of NT1 and the
345 effective value of "client min protocol".
347 See client max protocol for a full list of available protocols.
348 The values CORE, COREPLUS, LANMAN1, LANMAN2 are silently upgraded to NT1.
350 Default: client ipc min protocol = default
352 Example: client ipc min protocol = SMB3_11
354 ldap server require strong auth (G)
356 The ldap server require strong auth defines whether the
357 ldap server requires ldap traffic to be signed or
358 signed and encrypted (sealed). Possible values are no,
359 allow_sasl_over_tls and yes.
361 A value of no allows simple and sasl binds over all transports.
363 A value of allow_sasl_over_tls allows simple and sasl binds (without sign or seal)
364 over TLS encrypted connections. Unencrypted connections only
365 allow sasl binds with sign or seal.
367 A value of yes allows only simple binds over TLS encrypted connections.
368 Unencrypted connections only allow sasl binds with sign or seal.
370 Default: ldap server require strong auth = yes
374 This parameter determines whether or not smbd(8) will allow SMB1 clients
375 without extended security (without SPNEGO) to use NTLMv2 authentication.
377 If this option, lanman auth and ntlm auth are all disabled, then only
378 clients with SPNEGO support will be permitted. That means NTLMv2 is only
379 supported within NTLMSSP.
381 Default: raw NTLMv2 auth = no
385 This controls if and how strict the client will verify the peer's
386 certificate and name. Possible values are (in increasing order): no_check,
387 ca_only, ca_and_name_if_available, ca_and_name and as_strict_as_possible.
389 When set to no_check the certificate is not verified at all,
390 which allows trivial man in the middle attacks.
392 When set to ca_only the certificate is verified to be signed from a ca
393 specified in the "tls ca file" option. Setting "tls ca file" to a valid file
394 is required. The certificate lifetime is also verified. If the "tls crl file"
395 option is configured, the certificate is also verified against
398 When set to ca_and_name_if_available all checks from ca_only are performed.
399 In addition, the peer hostname is verified against the certificate's
400 name, if it is provided by the application layer and not given as
401 an ip address string.
403 When set to ca_and_name all checks from ca_and_name_if_available are performed.
404 In addition the peer hostname needs to be provided and even an ip
405 address is checked against the certificate's name.
407 When set to as_strict_as_possible all checks from ca_and_name are performed.
408 In addition the "tls crl file" needs to be configured. Future versions
409 of Samba may implement additional checks.
411 Default: tls verify peer = as_strict_as_possible
413 tls priority (G) (backported from Samba 4.3 to Samba 4.2)
415 This option can be set to a string describing the TLS protocols to be
416 supported in the parts of Samba that use GnuTLS, specifically the AD DC.
418 The default turns off SSLv3, as this protocol is no longer considered
419 secure after CVE-2014-3566 (otherwise known as POODLE) impacted SSLv3 use
420 in HTTPS applications.
422 The valid options are described in the GNUTLS Priority-Strings
423 documentation at http://gnutls.org/manual/html_node/Priority-Strings.html
425 Default: tls priority = NORMAL:-VERS-SSL3.0
431 o The default auth level for authenticated binds has changed from
432 DCERPC_AUTH_LEVEL_CONNECT to DCERPC_AUTH_LEVEL_INTEGRITY.
433 That means ncacn_ip_tcp:server is now implicitly the same
434 as ncacn_ip_tcp:server[sign] and offers a similar protection
435 as ncacn_np:server, which relies on smb signing.
437 o The following constraints are applied to SMB1 connections:
439 - "client lanman auth = yes" is now consistently
440 required for authenticated connections using the
441 SMB1 LANMAN2 dialect.
442 - "client ntlmv2 auth = yes" and "client use spnego = yes"
443 (both the default values), require extended security (SPNEGO)
444 support from the server. That means NTLMv2 is only used within
447 o Tools like "samba-tool", "ldbsearch", "ldbedit" and more obey the
448 default of "client ldap sasl wrapping = sign". Even with
449 "client ldap sasl wrapping = plain" they will automatically upgrade
450 to "sign" when getting LDAP_STRONG_AUTH_REQUIRED from the LDAP

553 Release Notes for Samba 4.2.9
555 =============================
558 This is a security release in order to address the following CVEs:
560 o CVE-2015-7560 (Incorrect ACL get/set allowed on symlink path)
561 o CVE-2016-0771 (Out-of-bounds read in internal DNS server)
568 All versions of Samba from 3.2.0 to 4.4.0rc3 inclusive are vulnerable to
569 a malicious client overwriting the ownership of ACLs using symlinks.
571 An authenticated malicious client can use SMB1 UNIX extensions to
572 create a symlink to a file or directory, and then use non-UNIX SMB1
573 calls to overwrite the contents of the ACL on the file or directory
577 All versions of Samba from 4.0.0 to 4.4.0rc3 inclusive, when deployed as
578 an AD DC and choose to run the internal DNS server, are vulnerable to an
579 out-of-bounds read issue during DNS TXT record handling caused by users
580 with permission to modify DNS records.
582 A malicious client can upload a specially constructed DNS TXT record,
583 resulting in a remote denial-of-service attack. As long as the affected
584 TXT record remains undisturbed in the Samba database, a targeted DNS
585 query may continue to trigger this exploit.
587 While unlikely, the out-of-bounds read may bypass safety checks and
588 allow leakage of memory from the server in the form of a DNS TXT reply.
590 By default only authenticated accounts can upload DNS records,
591 as "allow dns updates = secure only" is the default.
592 Any other value would allow anonymous clients to trigger this
593 bug, which is a much higher risk.

708 Release Notes for Samba 4.2.7
710 =============================
713 This is a security release in order to address the following CVEs:
715 o CVE-2015-3223 (Denial of service in Samba Active Directory
717 o CVE-2015-5252 (Insufficient symlink verification in smbd)
718 o CVE-2015-5299 (Missing access control check in shadow copy
720 o CVE-2015-5296 (Samba client requesting encryption vulnerable
722 o CVE-2015-8467 (Denial of service attack against Windows
723 Active Directory server)
724 o CVE-2015-5330 (Remote memory read in Samba LDAP server)
726 Please note that if building against a system libldb, the required
727 version has been bumped to ldb-1.1.24. This is needed to ensure
728 we build against a system ldb library that contains the fixes
729 for CVE-2015-5330 and CVE-2015-3223.
736 All versions of Samba from 4.0.0 to 4.3.2 inclusive (resp. all
737 ldb versions up to 1.1.23 inclusive) are vulnerable to
738 a denial of service attack in the samba daemon LDAP server.
740 A malicious client can send packets that cause the LDAP server in the
741 samba daemon process to become unresponsive, preventing the server
742 from servicing any other requests.
744 This flaw is not exploitable beyond causing the code to loop expending
748 All versions of Samba from 3.0.0 to 4.3.2 inclusive are vulnerable to
749 a bug in symlink verification, which under certain circumstances could
750 allow client access to files outside the exported share path.
752 If a Samba share is configured with a path that shares a common path
753 prefix with another directory on the file system, the smbd daemon may
754 allow the client to follow a symlink pointing to a file or directory
755 in that other directory, even if the share parameter "wide links" is
756 set to "no" (the default).
759 All versions of Samba from 3.2.0 to 4.3.2 inclusive are vulnerable to
760 a missing access control check in the vfs_shadow_copy2 module. When
761 looking for the shadow copy directory under the share path the current
762 accessing user should have DIRECTORY_LIST access rights in order to
763 view the current snapshots.
765 This was not being checked in the affected versions of Samba.
768 Versions of Samba from 3.2.0 to 4.3.2 inclusive do not ensure that
769 signing is negotiated when creating an encrypted client connection to
772 Without this a man-in-the-middle attack could downgrade the connection
773 and connect using the supplied credentials as an unsigned, unencrypted
777 Samba, operating as an AD DC, is sometimes operated in a domain with a
778 mix of Samba and Windows Active Directory Domain Controllers.
780 All versions of Samba from 4.0.0 to 4.3.2 inclusive, when deployed as
781 an AD DC in the same domain with Windows DCs, could be used to
782 override the protection against the MS15-096 / CVE-2015-2535 security
785 Prior to MS16-096 it was possible to bypass the quota of machine
786 accounts a non-administrative user could create. Pure Samba domains
787 are not impacted, as Samba does not implement the
788 SeMachineAccountPrivilege functionality to allow non-administrator
789 users to create new computer objects.
792 All versions of Samba from 4.0.0 to 4.3.2 inclusive (resp. all
793 ldb versions up to 1.1.23 inclusive) are vulnerable to
794 a remote memory read attack in the samba daemon LDAP server.
796 A malicious client can send packets that cause the LDAP server in the
797 samba daemon process to return heap memory beyond the length of the
800 This memory may contain data that the client should not be allowed to
801 see, allowing compromise of the server.
803 The memory may either be returned to the client in an error string, or
804 stored in the database by a suitabily privileged user. If untrusted
805 users can create objects in your database, please confirm that all DN
806 and name attributes are reasonable.

813 * BUG 11552: CVE-2015-8467: samdb: Match MS15-096 behaviour for

817 * BUG 11325: CVE-2015-3223: Fix LDAP \00 search expression attack DoS.
818 * BUG 11395: CVE-2015-5252: Fix insufficient symlink verification (file
819 access outside the share).
820 * BUG 11529: CVE-2015-5299: s3-shadow-copy2: Fix missing access check on
823 o Douglas Bagnall <douglas.bagnall@catalyst.net.nz>
824 * BUG 11599: CVE-2015-5330: Fix remote read memory exploit in LDB.

1535 Release Notes for Samba 4.2.0
1537 =============================
1540 This is is the first stable release of Samba 4.2.
1542 Samba 4.2 will be the next version of the Samba suite.
1545 Samba User Survey 2015
1546 ======================
1548 https://www.surveygizmo.com/s3/2020369/Samba-User-Survey-2015
1550 Please take our survey. It will help us improve Samba by understanding
1551 your knowledge and needs. The survey runs until end of March 2015 and
1552 won't ask for any personal info. The full results will be shared with
1553 the Samba Team, and statistical summaries will be shared with the
1554 Samba community after the SambaXP conference (http://sambaxp.org).
1557 IMPORTANT NOTE ABOUT THE SUPPORT END OF SAMBA 3
1558 =================================================
1560 With the final release of Samba 4.2, the last series of Samba 3 has
1561 been discontinued! People still running 3.6.x or earlier,should
1562 consider moving to a more recent and maintained version (4.0 - 4.2).
1563 One of the common misconceptions is that Samba 4.x automatically
1564 means "Active Directory only": This is wrong!
1566 Acting as an Active Directory Domain Controller is just one of the
1567 enhancements included in Samba 4.0 and later. Version 4.0 was just the
1568 next release after the 3.6 series and contains all the features of the
1569 previous ones - including the NT4-style (classic) domain support. This
1570 means you can update a Samba 3.x NT4-style PDC to 4.x, just as you've
1571 updated in the past (e.g. from 3.4.x to 3.5.x). You don't have to move
1572 your NT4-style domain to an Active Directory!
1574 And of course the possibility remains unchanged, to setup a new NT4-style
1575 PDC with Samba 4.x, like done in the past (e.g. with openLDAP backend).
1576 Active Directory support in Samba 4 is additional and does not replace
1577 any of these features. We do understand the difficulty presented by
1578 existing LDAP structures and for that reason there isn't a plan to
1579 decommission the classic PDC support. It remains tested by the continuous
1582 The code that supports the classic Domain Controller is also the same
1583 code that supports the internal 'Domain' of standalone servers and
1584 Domain Member Servers. This means that we still use this code, even
1585 when not acting as an AD Domain Controller. It is also the basis for
1586 some of the features of FreeIPA and so it gets development attention
1587 from that direction as well.
1593 Read the "Winbindd/Netlogon improvements" section (below) carefully!
1599 Transparent File Compression
1600 ============================
1602 Samba 4.2.0 adds support for the manipulation of file and folder
1603 compression flags on the Btrfs filesystem.
1604 With the Btrfs Samba VFS module enabled, SMB2+ compression flags can
1605 be set remotely from the Windows Explorer File->Properties->Advanced
1606 dialog. Files flagged for compression are transparently compressed
1607 and uncompressed when accessed or modified.
1609 Previous File Versions with Snapper
1610 ===================================
1612 The newly added Snapper VFS module exposes snapshots managed by
1613 Snapper for use by Samba. This provides the ability for remote
1614 clients to access shadow-copies via Windows Explorer using the
1615 "previous versions" dialog.
1617 Winbindd/Netlogon improvements
1618 ==============================
1620 The whole concept of maintaining the netlogon secure channel
1621 to (other) domain controllers was rewritten in order to maintain
1622 global state in a netlogon_creds_cli.tdb. This is the proper fix
1623 for a large number of bugs:
1625 https://bugzilla.samba.org/show_bug.cgi?id=6563
1626 https://bugzilla.samba.org/show_bug.cgi?id=7944
1627 https://bugzilla.samba.org/show_bug.cgi?id=7945
1628 https://bugzilla.samba.org/show_bug.cgi?id=7568
1629 https://bugzilla.samba.org/show_bug.cgi?id=8599
1631 In addition a strong session key is now required by default,
1632 which means that communication to older servers or clients
1633 might be rejected by default.
1635 For the client side we have the following new options:
1636 "require strong key" (yes by default), "reject md5 servers" (no by default).
1637 E.g. for Samba 3.0.37 you need "require strong key = no" and
1638 for NT4 DCs you need "require strong key = no" and "client NTLMv2 auth = no",
1640 On the server side (as domain controller) we have the following new options:
1641 "allow nt4 crypto" (no by default), "reject md5 client" (no by default).
1642 E.g. in order to allow Samba < 3.0.27 or NT4 members to work
1643 you need "allow nt4 crypto = yes"
1645 winbindd does not list group memberships for display purposes
1646 (e.g. getent group <domain\<group>) anymore by default.
1647 The new default is "winbind expand groups = 0" now,
1648 the reason for this is the same as for "winbind enum users = no"
1649 and "winbind enum groups = no". Providing this information is not always
1650 reliably possible, e.g. if there are trusted domains.
1652 Please consult the smb.conf manpage for more details on these new options.
1654 Winbindd use on the Samba AD DC
1655 ===============================
1657 Winbindd is now used on the Samba AD DC by default, replacing the
1658 partial rewrite used for winbind operations in Samba 4.0 and 4.1.
1660 This allows more code to be shared, more options to be honoured, and
1661 paves the way for support for trusted domains in the AD DC.
1663 If required the old internal winbind can be activated by setting
1664 'server services = +winbind -winbindd'. Upgrading users with a server
1665 services parameter specified should ensure they change 'winbind' to
1666 'winbindd' to obtain the new functionality.
1668 The 'samba' binary still manages the starting of this service, there
1669 is no need to start the winbindd binary manually.
1671 Winbind now requires secured connections
1672 ========================================
1674 To improve protection against rogue domain controllers we now require
1675 that when we connect to an AD DC in our forest, that the connection be
1676 signed using SMB Signing. Set 'client signing = off' in the smb.conf
1679 Also and DCE/RPC pipes must be sealed, set 'require strong key =
1680 false' and 'winbind sealed pipes = false' to disable.
1682 Finally, the default for 'client ldap sasl wrapping' has been set to
1683 'sign', to ensure the integrity of LDAP connections. Set 'client ldap
1684 sasl wrapping = plain' to disable.
1686 Larger IO sizes for SMB2/3 by default
1687 =====================================
1689 The default values for "smb2 max read", "smb2 max write" and "smb2 max trans"
1690 have been changed to 8388608 (8MiB) in order to match the default of
1696 The SMB2 protocol allows clients to aggressively cache files
1697 locally above and beyond the caching allowed by SMB1 and SMB2 oplocks.
1699 Called SMB2 leases, this can greatly reduce traffic on an SMB2
1700 connection. Samba 4.2 now implements SMB2 leases.
1702 It can be turned on by setting the parameter "smb2 leases = yes"
1703 in the [global] section of your smb.conf. This parameter is set
1704 to off by default until the SMB2 leasing code is declared fully stable.
1706 Improved DCERPC man in the middle detection
1707 ===========================================
1709 The DCERPC header signing has been implemented
1710 in addition to the dcerpc_sec_verification_trailer
1713 Overhauled "net idmap" command
1714 ==============================
1716 The command line interface of the "net idmap" command has been
1717 made systematic, and subcommands for reading and writing the autorid idmap
1718 database have been added. Note that the writing commands should be
1719 used with great care. See the net(8) manual page for details.
1724 The tdb library, our core mechanism to store Samba-specific data on disk and
1725 share it between processes, has been improved to support process shared robust
1726 mutexes on Linux. These mutexes are available on Linux and Solaris and
1727 significantly reduce the overhead involved with tdb. To enable mutexes for
1730 dbwrap_tdb_mutexes:* = yes
1732 in the [global] section of your smb.conf.
1734 Tdb file space management has also been made more efficient. This
1735 will lead to smaller and less fragmented databases.
1737 Messaging improvements
1738 ======================
1740 Our internal messaging subsystem, used for example for things like oplock
1741 break messages between smbds or setting a process debug level dynamically, has
1742 been rewritten to use unix domain datagram messages.
1747 Samba's file server clustering component CTDB is now integrated in the
1748 Samba tree. This avoids the confusion of compatibility of Samba and CTDB
1749 versions as existed previously.
1751 To build the Samba file server with cluster support, use the configure
1752 command line option --with-cluster-support. This will build clustered
1753 file server against the in-tree CTDB and will also build CTDB.
1754 Building clustered samba with previous versions of CTDB is no longer
1757 Samba Registry Editor
1758 =====================
1760 The utitlity to browse the samba registry has been overhauled by our Google
1761 Summer of Code student Chris Davis. Now samba-regedit has a
1762 Midnight-Commander-like theme and UI experience. You can browse keys and edit
1763 the diffent value types. For a data value type a hexeditor has been
1766 Bad Password Lockout in the AD DC
1767 =================================
1769 Samba's AD DC now implements bad password lockout (on a per-DC basis).
1771 That is, incorrect password attempts are tracked, and accounts locked
1772 out if too many bad passwords are submitted. There is also a grace
1773 period of 60 minutes on the previous password when used for NTLM
1774 authentication (matching Windows 2003 SP1: https://support2.microsoft.com/kb/906305).
1776 The relevant settings can be seen using 'samba-tool domain
1777 passwordsettings show' (the new settings being highlighted):
1779 Password informations for domain 'DC=samba,DC=example,DC=com'
1781 Password complexity: on
1782 Store plaintext passwords: off
1783 Password history length: 24
1784 Minimum password length: 7
1785 Minimum password age (days): 1
1786 Maximum password age (days): 42
1787 * Account lockout duration (mins): 30 *
1788 * Account lockout threshold (attempts): 0 *
1789 * Reset account lockout after (mins): 30 *
1791 These values can be set using 'samba-tool domain passwordsettings set'.
1793 Correct defaults in the smb.conf manpages
1794 =========================================
1796 The default values for smb.conf parameters are now correctly specified
1797 in the smb.conf manpage, even when they refer to build-time specified
1798 paths. Provided Samba is built on a system with the right tools
1799 (xsltproc in particular) required to generate our man pages, then
1800 these will be built with the exact same embedded paths as used by the
1801 configuration parser at runtime. Additionally, the default values
1802 read from the smb.conf manpage are checked by our test suite to match
1803 the values seen in testparm and used by the running binaries.
1805 Consistent behaviour between samba-tool testparm and testparm
1806 =============================================================
1808 With the exception of the registry backend, which remains only
1809 available in the file server, the behaviour of the smb.conf parser and
1810 the tools 'samba-tool testparm' and 'testparm' is now consistent,
1811 particularly with regard to default values. Except with regard to
1812 registry shares, it is no longer needed to use one tool on the AD
1813 DC, and another on the file server.
1818 A VFS module for basic WORM (Write once read many) support has been
1819 added. It allows an additional layer on top of a Samba share, that provides
1820 a basic set of WORM functionality on the client side, to control the
1821 writeability of files and folders.
1823 As the module is simply an additional layer, share access and permissions
1824 work like expected - only WORM functionality is added on top. Removing the
1825 module from the share configuration, removes this layer again. The
1826 filesystem ACLs are not affected in any way from the module and treated
1829 The module does not provide complete WORM functions, like some archiving
1830 products do! It is not audit-proof, because the WORM function is only
1831 available on the client side, when accessing a share through SMB! If
1832 the same folder is shared by other services like NFS, the access only
1833 depends on the underlying filesystem ACLs. Equally if you access the
1834 content directly on the server.
1836 For additional information, see
1837 https://wiki.samba.org/index.php/VFS/vfs_worm
1839 vfs_fruit, a VFS module for OS X clients
1840 ========================================
1842 A new VFS module that provides enhanced compatibility with Apple SMB
1843 clients and interoperability with a Netatalk 3 AFP fileserver.
1845 The module features enhanced performance with reliable named streams
1846 support, interoperability with special characters commonly used by OS
1847 X client (eg '*', '/'), integrated file locking and Mac metadata
1848 access with Netatalk 3 and enhanced performance by implementing
1849 Apple's SMB2 extension codenamed "AAPL".
1851 The modules behaviour is fully configurable, please refer to the
1852 manpage vfs_fruit for further details.
1854 smbclient archival improvements
1855 ===============================
1857 Archive creation and extraction support in smbclient has been rewritten
1858 to use libarchive. This fixes a number of outstanding bugs in Samba's
1859 previous custom tar implementation and also adds support for the
1860 extraction of zipped archives.
1861 smbclient archive support can be enabled or disabled at build time with
1862 corresponding --with[out]-libarchive configure parameters.
