Release Announcements
|
|
=====================
|
|
|
|
This is the first pre release of Samba 4.22. This is *not*
|
|
intended for production environments and is designed for testing
|
|
purposes only. Please report any defects via the Samba bug reporting
|
|
system at https://bugzilla.samba.org/.
|
|
|
|
Samba 4.22 will be the next version of the Samba suite.

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.
|
|
|
|
|
|
