UPGRADING
=========
NEW FEATURES/CHANGES
====================
SMB3 Directory Leases
---------------------
Starting with Samba 4.22 SMB3 Directory Leases are supported. The new global option "smb3 directory leases" controls whether the feature is enabled or not. By default, SMB3 Directory Leases are enabled on non-clustered Samba and disabled on clustered Samba, based on the "clustering" option. See man smb.conf for more details.
SMB3 Directory Leases allow clients to cache directory listings and, depending on the workload, result in a decent reduction in SMB requests from clients.
Netlogon Ping over LDAP and LDAPS
---------------------------------
Samba must query domain controller information via simple queries on the AD rootdse's netlogon attribute. Typically this is done via connectionless LDAP, using UDP on port 389. The same information is also available via classic LDAP rootdse queries over TCP. Samba can now be configured to use TCP via the new "client netlogon ping protocol" parameter to enable running in environments where firewalls completely block port 389 or UDP traffic to domain controllers.
REMOVED FEATURES
================
The "nmbd proxy logon" feature was removed. This was used before Samba4 acquired a NBT server.
The parameter "cldap port" has been removed. CLDAP runs over UDP port 389, we don't see a reason why this should ever be changed to a different port. Moreover, we had several places in the code where Samba did not respect this parameter, so the behaviour was at least inconsistent.
fruit:posix_rename
------------------
This option of the vfs_fruit VFS module that could be used to enable POSIX directory rename behaviour for OS X clients has been removed as it could result in severe problems for Windows clients.
As a possible workaround it is possible to prevent creation of .DS_Store files (a Finder thingy to store directory view settings) on network mounts by running
$ defaults write com.apple.desktopservices DSDontWriteNetworkStores true
on the Mac.
smb.conf changes
================
Parameter Name Description Default
-------------- ----------- -------
smb3 directory leases New Auto
vfs mkdir use tmp name New Auto
client netlogon ping protocol New cldap
fruit:posix_rename Removed
cldap port Removed

The Samba Team
The release candidate for Samba 4.22 is now available for download, introducing new features including SMB3 Directory Leases, which enable clients to cache directory listings, thereby minimizing SMB requests. The global option "smb3 directory leases" governs the activation or deactivation of this feature. Samba is now capable of utilizing TCP through the "client netlogon ping protocol" parameter, facilitating operation in environments where firewalls restrict access to port 389 or UDP traffic directed towards domain controllers. The "nmbd proxy logon" feature has been eliminated, and the "cldap port" parameter has been removed due to inconsistent behavior.
