[Samba] "[Announce] Samba 4.6.0rc1 Available for Download"
Release Announcements
====================
This is the first preview release of Samba 4.6. 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 4.6 will be the next version of the Samba suite.
UPGRADING
========
vfs_fruit option "fruit:resource" spelling correction
-----------------------------------------------------
Due to a spelling error in the vfs_fruit option parsing for the
"fruit:resource"
option, users who have set this option in their smb.conf were still using the
default setting "fruit:resource = file" as the parser was looking for
the string
"fruit:ressource" (two "s").
After upgrading to this Samba version 4.6, you MUST either remove the option
from your smb.conf or set it to the default "fruit:resource = file",
otherwise
your macOS clients will not be able to access the resource fork data.
This version Samba 4.6 accepts both the correct and incorrect spelling, but the
next Samba version 4.7 will not accept the wrong spelling.
Users who were using the wrong spelling "ressource" with two
"s" can keep the
setting, but are advised to switch to the correct spelling.
ID Mapping
----------
We discovered that the majority of users have an invalid or incorrect
ID mapping configuration. We implemented checks in the 'testparm' tool
to
validate the ID mapping configuration. You should run it and check if it prints
any warnings or errors after upgrading! If it does you should fix them. See the
'IDENTITY MAPPING CONSIDERATIONS' section in the smb.conf manpage.
There are some ID mapping backends which are not allowed to be used for the
default backend. Winbind will no longer start if an invalid backend is
configured as the default backend.
To avoid problems in future we advise all users to run 'testparm' after
changing the smb.conf file!
NEW FEATURES/CHANGES
===================
Kerberos client encryption types
--------------------------------
Some parts of Samba (most notably winbindd) perform Kerberos client
operations based on a Samba-generated krb5.conf file. A new
parameter, "kerberos encryption types" allows configuring the
encryption types set in this file, thereby allowing the user to
enforce strong or legacy encryption in Kerberos exchanges.
The default value of "all" is compatible with previous behavior,
allowing
all encryption algorithms to be negotiated. Setting the parameter to
"strong"
only allows AES-based algorithms to be negotiated. Setting the parameter to
"legacy" allows only RC4-HMAC-MD5 - the legacy algorithm for Active
Directory.
This can solves some corner cases of mixed environments with Server 2003R2 and
newer DCs.
Printing
--------
Support for uploading printer drivers from newer Windows clients (Windows 10)
has been added until our implementation of [MS-PAR] protocol is ready.
Several issues with uploading different printing drivers have been addressed.
The OS Version for the printing server has been increased to announce
Windows Server 2003 R2 SP2. If a driver needs a newer version then you should
check the smb.conf manpage for details.
new option for owner inheritance
--------------------------------
The "inherit owner" smb.conf parameter instructs smbd to set the
owner of files to be the same as the parent directory's owner.
Up until now, this parameter could be set to "yes" or "no".
A new option, "unix only", enables this feature only for the UNIX
owner
of the file, not affecting the SID owner in the Windows NT ACL of the
file. This can be used to emulate something very similar to folder quotas.
Multi-process Netlogon support
------------------------------
The Netlogon server in the Samba AD DC can now run as multiple
processes. The Netlogon server is a part of the AD DC that handles
NTLM authentication on behalf of domain members, including file
servers, NTLM-authenticated web servers and 802.1x gateways. The
previous restriction to running as a single process has been removed,
and it will now run in the same process model as the rest of the
'samba' binary.
As part of this change, the NETLOGON service will now run on a distinct
TCP port, rather than being shared with all other RPC services (LSA,
SAMR, DRSUAPI etc).
new options for controlling TCP ports used for RPC services
-----------------------------------------------------------
The new 'rpc server port' option controls the default port used for
RPC services other than Netlogon. The Netlogon server honours instead
the 'rpc server port:netlogon' option. The default value for both
these options is the first available port including or after 1024.
Improve AD performance and replication improvements
---------------------------------------------------
Samba's LDB and replication code continues to improve, particularly in
respect to the handling of large numbers of linked attributes. We now
respect an 'uptodateness vector' which will dramatically reduce the
over-replication of links from new DCs. We have also made the parsing
of on-disk linked attributes much more efficient.
DNS improvements
----------------
The samba-tool dns subcommand is now much more robust and can delete
records in a number of situations where it was not possible to do so
in the past.
On the server side, DNS names are now more strictly validated.
CTDB changes
------------
* "ctdb event" is a new top-level command for interacting with event
scripts
"ctdb event status" replaces "ctdb scriptstatus" - the
latter is
maintained for backward compatibility but the output format has been
cleaned up
"ctdb event run" replaces "ctdb eventscript"
"ctdb event script enable" replaces "ctdb enablescript"
"ctdb event script disable" replaces "ctdb disablescript"
The new command "ctdb event script list" lists event scripts.
* CTDB's back-end for running event scripts has been replaced by a
separate, long-running daemon ctdbd_eventd.
* Running ctdb interactively will log to stderr
* CTDB logs now include process id for each process
* CTDB tags log messages differently. Changes include:
ctdb-recoverd: Messages from CTDB's recovery daemon
ctdb-recovery: Messages from CTDB database recovery
ctdb-eventd: Messages from CTDB's event daemon
ctdb-takeover: Messgaes from CTDB's public IP takeover subsystem
* The mapping between symbolic and numeric debug levels has changed
Configurations containing numeric debug levels should be updated.
Symbolic debug levels are recommended. See the DEBUG LEVEL section
of ctdb(7) for details.
* Tunable IPAllocAlgorithm replaces LCP2PublicIPs, DeterministicIPs
See ctdb-tunables(7) for details
* CTDB's configuration tunables should be consistently set across a cluster
This has always been the cases for most tunables but this fact is
now documented.
* CTDB ships with recovery lock helper call-outs for etcd and Ceph RADOS
To build/install these, use the --enable-etcd-reclock and
--enable-ceph-reclock configure options.

Hello, First of all, happy New Year to everyone… What better way to start the New Year with a new version of Samba! There’s no mention if the Win2012R2 schema support is ready for production. Can we have an update on this please? Alternatively, are there Bugzilla reports that we can follow to get updates? Thank You!

I don't normally track new features like this in Bugzilla, but you can see if there is ticket there. Honestly, I had really expected that one of our users would have written the patches by now, at least to have Samba use the new schema in a fresh provision. That part is mostly a matter of parsing the supplied schema files and loading it in the DB. That code is all in Python. Upgrades are harder, and making it come in over replication is probably also a pain, but 4.5 should have fixed some of that, but clearly not everything.
