This is the first stable release of the Samba 4.14 release series. Please read the release notes carefully before upgrading.

NEW FEATURES/CHANGES

Here is a copy of a clarification note added to the Samba code in the file: VFS-License-clarification.txt.

A clarification of our GNU GPL License enforcement boundary within the Samba Virtual File System (VFS) layer.

Samba is licensed under the GNU GPL. All code committed to the Samba project or that creates a “modified version” or software “based on” Samba must be either licensed under the GNU GPL or a compatible license.

Samba has several plug-in interfaces where external code may be called from Samba GNU GPL licensed code. The most important of these is the Samba VFS layer.

Samba VFS modules are intimately connected by header files and API definitions to the part of the Samba code that provides file services, and as such, code that implements a plug-in Samba VFS module must be licensed under the GNU GPL or a compatible license.

However, Samba VFS modules may themselves call third-party external libraries that are not part of the Samba project and are externally developed and maintained.

As long as these third-party external libraries do not use any of the Samba internal structure, APIs or interface definitions created by the Samba project (to the extent that they would be considered subject to the GNU GPL), then the Samba Team will not consider such third-party external libraries called from Samba VFS modules as “based on” and/or creating a “modified version” of the Samba code for the purposes of GNU GPL. Accordingly, we do not require such libraries be licensed under the GNU GPL or a GNU GPL compatible license.

• VFS – The effort to modernize Samba’s VFS interface has reached a major milestone with the next release Samba 4.14. For details please refer to the documentation at source3/modules/The_New_VFS.txt or visit the
• printing – Publishing printers in AD is more reliable and more printer features are added to the published information in AD. Samba now also supports Windows drivers for the ARM64 architecture.
• Client Group Policy – This release extends Samba to support Group Policy functionality for Winbind clients. Active Directory Administrators can set policies that apply Sudoers configuration, and cron jobs to run hourly, daily, weekly or monthly.
  To enable the application of Group Policies on a client, set the global smb.conf option ‘apply group policies’ to ‘yes’. Policies are applied on an interval of every 90 minutes, plus a random offset between 0 and 30 minutes.
  Policies applied by Samba are ‘non-tattooing’, meaning that changes can be reverted by executing the `samba-gpupdate –unapply` command. Policies can be re-applied using the `samba-gpupdate –force` command. To view what policies have been or will be applied to a system, use the `samba-gpupdate –rsop` command.
  Administration of Samba policy requires that a Samba ADMX template be uploaded to the SYSVOL share. The samba-tool command `samba-tool gpo admxload` is provided as a convenient method for adding this policy. Once uploaded, policies can be modified in the Group Policy Management Editor under Computer Configuration/Policies/Administrative Templates. Alternatively, Samba policy may be managed using the `samba-tool gpo manage` command. This tool does not require the admx templates to be installed.
• Python 3.6 or later required – Samba’s minimum runtime requirement for python was raised to Python 3.6 with samba 4.13. Samba 4.14 raises this minimum version to Python 3.6 also to build Samba. It is no longer possible to build Samba (even just the file server) with Python versions 2.6 and 2.7. As Python 2.7 has been End Of Life upstream since April 2020, Samba is dropping ALL Python 2.x support in this release.
• Miscellaneous samba tool changes – The ‘samba-tool’ subcommands to manage AD objects (eg users, computers and groups) now consistently use the “add” command when adding a new object to the AD. The previous deprecation warnings when using the ‘add’ commands have been removed. For compatibility reasons, both the ‘add’ and ‘create’ commands can be used now.
  Users, groups and contacts can now be renamed with the respective rename commands.
  Locked users can be unlocked with the new ‘samba-tool user unlock’ command.
  The ‘samba-tool user list’ and ‘samba-tool group listmembers’ commands provide additional options to hide expired and disabled user accounts (–hide-expired and –hide-disabled).

CTDB CHANGES

• The NAT gateway and LVS features now uses the term “leader” to refer to the main node in a group through which traffic is routed and “follower” for other members of a group. The command for determining the leader has changed to “ctdb natgw leader” (from “ctdb natgw master”). The configuration keyword for indicating that a node can not be the leader of a group has changed to “follower-only” (from “slave-only”). Identical changes were made for LVS.
• Remove “ctdb isnotrecmaster” command. It isn’t used by CTDB’s scripts and can be checked by users with “ctdb pnn” and “ctdb recmaster”.
