Release Announcements
=====================
-This is the first preview release of Samba 4.6. This is *not*
+This is the first preview release of Samba 4.11. 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 4.11 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").
+NEW FEATURES/CHANGES
+====================
-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.
+Default samba process model
+---------------------------
-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.
+The default for the --model argument passed to the samba executable has changed
+from 'standard' to 'prefork'. This means a difference in the number of samba
+child processes that are created to handle client connections. The previous
+default would create a separate process for every LDAP or NETLOGON client
+connection. For a network with a lot of persistent client connections, this
+could result in significant memory overhead. Now, with the new default of
+'prefork', the LDAP, NETLOGON, and KDC services will create a fixed number of
+worker processes at startup and share the client connections amongst these
+workers. The number of worker processes can be configured by the 'prefork
+children' setting in the smb.conf (the default is 4).
-Users who were using the wrong spelling "ressource" with two "s" can keep the
-setting, but are advised to switch to the correct spelling.
+Authentication Logging.
+-----------------------
-ID Mapping
-----------
-We discovered that the majority of users have an invalid or incorrect
-ID mapping configuration. We implemented checks in the 'testparm' tool to
-validate the ID mapping configuration. You should run it and check if it prints
-any warnings or errors after upgrading! If it does you should fix them. See the
-'IDENTITY MAPPING CONSIDERATIONS' section in the smb.conf manpage.
-There are some ID mapping backends which are not allowed to be used for the
-default backend. Winbind will no longer start if an invalid backend is
-configured as the default backend.
-
-To avoid problems in future we advise all users to run 'testparm' after
-changing the smb.conf file!
+Winbind now logs PAM_AUTH and NTLM_AUTH events, a new attribute "logonId" has
+been added to the Authentication JSON log messages. This contains a random
+logon id that is generated for each PAM_AUTH and NTLM_AUTH request and is passed
+to SamLogon, linking the windbind and SamLogon requests.
-NEW FEATURES/CHANGES
-====================
+The serviceDescription of the messages is set to "winbind", the authDescription
+is set to one of:
+ "PASSDB, <command>, <pid>"
+ "PAM_AUTH, <command>, <pid>"
+ "NTLM_AUTH, <command>, <pid>"
+where:
+ <command> is the name of the command makinmg the winbind request i.e. wbinfo
+ <pid> is the process id of the requesting process.
+
+The version of the JSON Authentication messages has been changed to 1.2 from 1.1
-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.
-
-Printing
---------
-Support for uploading printer drivers from newer Windows clients (Windows 10)
-has been added until our implementation of [MS-PAR] protocol is ready.
-Several issues with uploading different printing drivers have been addressed.
-
-The OS Version for the printing server has been increased to announce
-Windows Server 2003 R2 SP2. If a driver needs a newer version then you should
-check the smb.conf manpage for details.
-
-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
================
+Web server
+----------
+
+As a leftover from work related to the Samba Web Administration Tool (SWAT),
+Samba still supported a Python WSGI web server (which could still be turned on
+from the 'server services' smb.conf parameter). This service was unused and has
+now been removed from Samba.
+
