UPGRADING
NEW FEATURES/CHANGES
====================
-New Minimum MIT Krb5 version for Samba AD Domain Controller
------------------------------------------------------------
+LDB no longer a standalone tarball
+----------------------------------
-Samba now requires MIT 1.21 when built against a system MIT Krb5 and
-acting as an Active Directory DC. This addresses the issues that were
-fixed in CVE-2022-37967 (KrbtgtFullPacSignature) and ensures that
-Samba builds against the MIT version that allows us to avoid that
-attack.
+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.
-Removed dependency on Perl JSON module
---------------------------------------
-
-Distributions are advised that the Perl JSON package is no longer
-required by Samba builds that use the imported Heimdal. The build
-instead uses Perl's JSON::PP built into recent perl5 versions.
-
-Current lists of packages required by Samba for major distributions
-are found in the bootstrap/generated-dists/ directory of a Samba
-source tree. While there will be some differences - due to features
-chosen by packagers - comparing these lists with the build dependencies
-in a package may locate other dependencies we no longer require.
-
-samba-tool user getpassword / syncpasswords ;rounds= change
------------------------------------------------------------
-
-The password access tool "samba-tool user getpassword" and the
-password sync tool "samba-tool user syncpasswords" allow attributes to
-be chosen for output, and accept parameters like
-pwdLastSet;format=GeneralizedTime
-
-These attributes then appear, in the same format, as the attributes in
-the LDIF output. This was not the case for the ;rounds= parameter of
-virtualCryptSHA256 and virtualCryptSHA512, for example as
---attributes="virtualCryptSHA256;rounds=50000"
+If you need ldb as a public library, say to build sssd, then use
+ ./configure --private-libraries='!ldb'
-This release makes the behaviour consistent between these two
-features. Installations using GPG-encrypted passwords (or plaintext
-storage) and the rounds= option, will find the output has changed
+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.
-from:
-virtualCryptSHA256: {CRYPT}$5$rounds=2561$hXem.M9onhM9Vuix$dFdSBwF
+This approach has been demonstrated already in Debian, which is already
+building Samba and LDB is this way.
-to:
-virtualCryptSHA256;rounds=2561: {CRYPT}$5$rounds=2561$hXem.M9onhM9Vuix$dFdSBwF
+As part of this work, the pyldb-util public library, not known to be
+used by any other software, is made private to Samba.
-Group Managed service account client-side features
---------------------------------------------------
-
-samba-tool has been extended to provide client-side support for Group
-Managed Service accounts. These accounts have passwords that change
-automatically, giving the advantages of service isolation without risk
-of poor, unchanging passwords.
-
-Where possible, Samba's existing samba-tool password handling
-commands, which in the past have only operated against the local
-sam.ldb have been extended to permit operation against a remote server
-with authenticated access to "-H ldap://$DCNAME"
+LDB Module API Python bindings removed
+--------------------------------------
-Supported operations include:
- - reading the current and previous gMSA password via
- "samba-tool user getpassword"
+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.
REMOVED FEATURES
================
-Get locally logged on users from utmp
--------------------------------------
-
-The Workstation Service Remote Protocol [MS-WKST] calls NetWkstaGetInfo
-level 102 and NetWkstaEnumUsers level 0 and 1 return the list of locally
-logged on users. Samba was getting the list from utmp, which is not
-Y2038 safe. This feature has been completely removed and Samba will
-always return an empty list.
-
smb.conf changes
================
Parameter Name Description Default
-------------- ----------- -------
- smb3 unix extensions Per share -
