Release Announcements
---------------------
This is the latest stable release of the Samba 4.22 release series.
Important Change in Upcoming Microsoft Update
---------------------------------------------
On 8th of July, Microsoft will release an important security update for
Active Directory Domain Controllers for Windows Server versions prior to
2025.
This update includes a change to the Microsoft RPC Netlogon protocol,
which improves security by tightening access checks for a set of RPC
requests. Samba running as domain members in these environments will be
impacted by this change if a specific configuration is used, see below
for which configuration is affected.
Windows Server version 2025 is already equipped with these specific
security hardenings, and Microsoft is now planning to deploy them to all
supported Windows Server versions down to Windows Server 2008.
Who is affected?
Samba installations acting as member servers in Windows AD domains will
be affected if they are configured to use the 'ad' idmapping backend.
Samba servers not using this configuration will not be affected by the
change – at least to our current knowledge and understanding of the
change – and no further action is required.
Current versions of Samba with the affected configuration will no longer
function correctly once the Microsoft update has been applied. Users
will not be able to connect to the SMB service provided by Samba for any
domain configured to use the 'ad' idmapping backend.
