Release Announcements ===================== This is the third release candidate 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. 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 CHANGES SINCE 4.22.0rc2 ======================= o Douglas Bagnall * BUG 15738: Creation of GPOs applicable to more than one group is impossible with Samba 4.20.0 and later. o Bjoern Baumbach * BUG 15806: samba-tool acl commands broken for relative path names * BUG 15807: pysmbd seg faults when file is not found. o Ralph Boehme * BUG 15796: Spotlight search results don't show file size and creation date. o Pavel Filipenský * BUG 15759: net ads create/join/winbind producing unix dysfunctional keytabs. o Volker Lendecke * BUG 15806: samba-tool acl commands broken for relative path names. * BUG 15807: pysmbd seg faults when file is not found. o Stefan Metzmacher * BUG 15680: Trust domains are not created. o Andreas Schneider * BUG 15680: Trust domains are not created. o Shweta Sodani * BUG 15703: General improvements for vfs_ceph_new module.
