Release Announcements
|
|
=====================
|
|
|
|
This is the first pre release of Samba 4.19. 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 4.19 will be the next version of the Samba suite.

UPGRADING

NEW FEATURES/CHANGES
|
|
====================
|
|
|
|
Migrated smbget to use common command line parser
|
|
-------------------------------------------------
|
|
|
|
The smbget utility implemented its own command line parsing logic. After
|
|
discovering an issue we decided to migrate it to use the common command line
|
|
parser. This has some advantages as you get all the feature it provides like
|
|
Kerberos authentication. The downside is that breaks the options interface.
|
|
The support for smbgetrc has been removed. You can use an authentication file
|
|
if needed, this is documented in the manpage.
|
|
|
|
Please check the smbget manpage or --help output.
|
|
|
|
gpupdate changes
|
|
----------------
|
|
|
|
The libgpo.get_gpo_list function has been deprecated in favor of
|
|
an implementation written in python. The new function can be imported via
|
|
`import samba.gp`. The python implementation connects to Active Directory
|
|
using the SamDB module, instead of ADS (which is what libgpo uses).
|
|
|
|
Improved winbind logging and a new tool for parsing the winbind logs
|
|
--------------------------------------------------------------------
|
|
|
|
Winbind logs (if smb.conf 'winbind debug traceid = yes' is set) contain new
|
|
trace header fields 'traceid' and 'depth'. Field 'traceid' allows to track the
|
|
trace records belonging to the same request. Field 'depth' allows to track the
|
|
request nesting level. A new tool samba-log-parser is added for better log
|
|
parsing.
|
|
|
|
AD database prepared to FL 2016 standards for new domains
|
|
---------------------------------------------------------
|
|
|
|
While Samba still provides only Functional Level 2008R2 by default,
|
|
Samba as an AD DC will now, in provision ensure that the blank
|
|
database is already prepared for Functional Level 2016, with AD Schema
|
|
2019.
|
|
|
|
This preparation is of the default objects in the database, adding
|
|
containers for Authentication Policies, Authentication Silos and AD
|
|
claims in particular. These DB objects must be updated to allow
|
|
operation of the new features found in higher functional levels.
|
|
|
|
Kerberos Claims, Authentication Silos and NTLM authentication policies
|
|
----------------------------------------------------------------------
|
|
|
|
An initial, partial implementation of Active Directory Functional
|
|
Level 2012, 2012R2 and 2016 is available in this release.
|
|
|
|
While we continue to develop these features, existing domains can
|
|
test the feature by selecting the functional level in provision or
|
|
raising the DC functional level by setting
|
|
|
|
ad dc functional level = 2016
|
|
|
|
in the smb.conf
|
|
|
|
The smb.conf file on each DC must have 'ad dc functional level = 2016'
|
|
set to have the partially complete feature available. This will also,
|
|
at first startup, update the server's own AD entry with the configured
|
|
functional level.
|
|
|
|
For new domains, add these parameters to 'samba-tool provision'
|
|
|
|
--option="ad dc functional level = 2016" --function-level=2016
|
|
|
|
The second option, setting the overall domain functional level
|
|
indicates that all DCs should be at this functional level.
|
|
|
|
To raise the domain functional level of an existing domain, after
|
|
updating the smb.conf and restarting Samba run
|
|
samba-tool domain schemaupgrade --schema=2019
|
|
samba-tool domain functionalprep --function-level=2016
|
|
samba-tool domain level raise --domain-level=2016 --forest-level=2016
|
|
|
|
Updated GnuTLS requirement / in-tree cryptography removal
|
|
----------------------------------------------------------
|
|
|
|
Samba requires GnuTLS 3.6.13 and prefers GnuTLS 3.6.14 or later.
|
|
|
|
This has allowed Samba to remove all of our in-tree cryptography,
|
|
except that found in our Heimdal import. Samba's runtime cryptography
|
|
needs are now all provided by GnuTLS.
|
|
|
|
(The GnuTLS vesion requirement is raised to 3.7.2 on systems without
|
|
the Linux getrandom())
|
|
|
|
We also use Python's cryptography module for our testing.
|
|
|
|
The use of well known cryptography libraries makes Samba easier for
|
|
end-users to validate and deploy, and for distributors to ship. This
|
|
is the end of a very long journey for Samba.
