UPGRADING
NEW FEATURES/CHANGES
====================
+LDB no longer a standalone tarball
+----------------------------------
-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.
+LDB, Samba's LDAP-like local database and the power behind the Samba
+AD DC, is no longer available to build as a distinct tarball, but is
+instead provided as an optional public library.
-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.
+If you need ldb as a public library, say to build sssd, then use
+ ./configure --private-libraries='!ldb'
-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.
+This re-integration allows LDB tests to use the Samba's full selftest
+system, including our knownfail infrastructure, and decreases the work
+required during security releases as a coordinated release of the ldb
+tarball is not also required.
-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.
-
-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".
+This approach has been demonstrated already in Debian, which is already
+building Samba and LDB is this way.
+As part of this work, the pyldb-util public library, not known to be
+used by any other software, is made private to Samba.
-NT4-like 'classic' Samba domain controllers
--------------------------------------------
-
-Samba 4.13 deprecates Samba's original domain controller mode.
-
-Sites using Samba as a Domain Controller should upgrade from the
-NT4-like 'classic' Domain Controller to a Samba Active Directory DC
-to ensure full operation with modern windows clients.
-
-SMBv1 only protocol options deprecated
+LDB Module API Python bindings removed
--------------------------------------
-A number of smb.conf parameters for less-secure authentication methods
-which are only possible over SMBv1 are deprecated in this release.
+The LDB Modules API, which we do not promise a stable ABI or API for,
+was wrapped in python in early LDB development. However that wrapping
+never took into account later changes, and so has not worked for a
+number of years. Samba 4.21 and LDB 2.10 removes this unused and
+broken feature.
