+This is the first preview release of Samba 4.7. This is *not*
intended for production environments and is designed for testing
purposes only. Please report any defects via the Samba bug reporting
system at https://bugzilla.samba.org/.
-Samba 4.6 will be the next version of the Samba suite.
+Samba 4.7 will be the next version of the Samba suite.
UPGRADING
=========
-vfs_fruit option "fruit:resource" spelling correction
------------------------------------------------------
-
-Due to a spelling error in the vfs_fruit option parsing for the "fruit:resource"
-option, users who have set this option in their smb.conf were still using the
-default setting "fruit:resource = file" as the parser was looking for the string
-"fruit:ressource" (two "s").
-
-After upgrading to this Samba version 4.6, you MUST either remove the option
-from your smb.conf or set it to the default "fruit:resource = file", otherwise
-your macOS clients will not be able to access the resource fork data.
-
-This version Samba 4.6 accepts both the correct and incorrect spelling, but the
-next Samba version 4.7 will not accept the wrong spelling.
-
-Users who were using the wrong spelling "ressource" with two "s" can keep the
-setting, but are advised to switch to the correct spelling.
NEW FEATURES/CHANGES
====================
-Kerberos client encryption types
---------------------------------
-Some parts of Samba (most notably winbindd) perform Kerberos client
-operations based on a Samba-generated krb5.conf file. A new
-parameter, "kerberos encryption types" allows configuring the
-encryption types set in this file, thereby allowing the user to
-enforce strong or legacy encryption in Kerberos exchanges.
-
-The default value of "all" is compatible with previous behavior, allowing
-all encryption algorithms to be negotiated. Setting the parameter to "strong"
-only allows AES-based algorithms to be negotiated. Setting the parameter to
-"legacy" allows only RC4-HMAC-MD5 - the legacy algorithm for Active Directory.
-This can solves some corner cases of mixed environments with Server 2003R2 and
-newer DCs.
-
-
-new option for owner inheritance
---------------------------------
-The "inherit owner" smb.conf parameter instructs smbd to set the
-owner of files to be the same as the parent directory's owner.
-Up until now, this parameter could be set to "yes" or "no".
-A new option, "unix only", enables this feature only for the UNIX owner
-of the file, not affecting the SID owner in the Windows NT ACL of the
-file. This can be used to emulate something very similar to folder quotas.
-
-
-REMOVED FEATURES
-================
-
+The "strict sync" global parameter has been changed from
+a default of "no" to "yes". This means smbd will by default
+obey client requests to synchronize unwritten data in operating
+system buffers safely onto disk. This is a safer default setting
+for modern SMB1/2/3 clients.
+
+Authentication and Authorization audit support
+----------------------------------------------
+
+Detailed authentication and authorization audit information is now
+logged to Samba's debug logs under the "auth_audit" debug class,
+including in particular the client IP address triggering the audit
+line. Additionally, if Samba is compiled against the jansson JSON
+library, a JSON representation is logged under the "auth_json_audit"
+debug class.
+
+Audit support is comprehensive for all authentication and
+authorisation of user accounts in the Samba Active Directory Domain
+Controller, as well as the implicit authentication in password
+changes. In the file server and classic/NT4 domain controller, NTLM
+authentication, SMB and RPC authorization is covered, however password
+changes are not at this stage, and this support is not currently
+backed by a testsuite.
smb.conf changes
================
Parameter Name Description Default
-------------- ----------- -------
- kerberos encryption types New all
- inherit owner New option
- fruit:resource Spelling correction
+ auth event notification New parameter no
+ auth methods Deprecated
+ map untrusted to domain Deprecated
+ strict sync Default changed yes
+
+Removal of lpcfg_register_defaults_hook()
+-----------------------------------------
+The undocumented and unsupported function lpcfg_register_defaults_hook()
+that was used by external projects to call into Samba and modify
+smb.conf default parameter settings has been removed. If your project
+was using this call please raise the issue on
+samba-technical@lists.samba.org in order to design a supported
+way of obtaining the same functionality.
+
+Change of loadable module interface
+-----------------------------------
+
+The _init function of all loadable modules in Samba has changed
+from:
+
+NTSTATUS _init(void);
+
+to:
+
+NTSTATUS _init(TALLOC_CTX *);
+
+This allows a program loading a module to pass in a long-lived
+talloc context (which must be guaranteed to be alive for the
+lifetime of the module). This allows modules to avoid use of
+the talloc_autofree_context() (which is inherently thread-unsafe)
+and still be valgrind-clean on exit. Modules that don't need to
+free long-lived data on exist should use the NULL talloc context.
KNOWN ISSUES
