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/.

UPGRADING
=========
-NTLMv1 authentication disabled by default
------------------------------------------
-
-In order to improve security we have changed
-the default value for the "ntlm auth" option from
-"yes" to "no". This may have impact on very old
-client which doesn't support NTLMv2 yet.
-
-The primary user of NTLMv1 is MSCHAPv2 for VPNs and 802.1x.
-
-By default Samba will only allow NTLMv2 via NTLMSSP now,
-as we have the following default "lanman auth = no",
-"ntlm auth = no" and "raw NTLMv2 auth = no".
-
NEW FEATURES/CHANGES
====================
-Support for LDAP_SERVER_NOTIFICATION_OID
-----------------------------------------
-
-The ldap server has support for the LDAP_SERVER_NOTIFICATION_OID
-control. This can be used to monitor the active directory database
-for changes.
-
-KCC improvements for sparse network replication
------------------------------------------------
-
-The Samba KCC will now be the default knowledge consistency checker in
-Samba AD. Instead of using full mesh replication between every DC, the
-KCC will set up connections to optimize replication latency and cost
-(using site links to calculate the routes). This change should allow
-larger domains to function significantly better in terms of replication
-traffic and the time spent performing DRS replication.
-
-VLV - Virtual List View
------------------------
-
-The VLV Control allows applications to page the LDAP directory in the
-way you might expect a live phone book application to operate, without
-first downloading the entire directory.
-
-DRS Replication for the AD DC
------------------------------
-
-DRS Replication in Samba 4.5 is now much more efficient in handling
-linked attributes, particularly in large domains with over 1000 group
-memberships or other links.
-
-Replication is also much more reliable in the handling of tree
-renames, such as the rename of an organizational unit containing many
-users. Extensive tests have been added to ensure this code remains
-reliable, particularly in the case of conflicts between objects added
-with the same name on different servers.
-
-Schema updates are also handled much more reliably.
-
-replPropertyMetaData Changes
-----------------------------
-
-During the development of the DRS replication, tests showed that Samba
-stores the replPropertyMetaData object incorrectly. To address this,
-be aware that dbcheck will now detect and offer to fix all objects in
-the domain for this error.
-
-Linked attributes on deleted objects
-------------------------------------
-
-In Active Directory, an object that has been tombstoned or recycled
-has no linked attributes. However, Samba incorrectly maintained such
-links, slowing replication and run-time performance. dbcheck now
-offers to remove such links, and they are no longer kept after the
-object is tombstoned or recycled.
-
-Improved AD DC performance
---------------------------
-
-Many other improvements have been made to our LDAP database layer in
-the AD DC, to improve performance, both during samba-tool domain
-provision and at runtime.
-
-Other dbcheck improvements
---------------------------
-
- - samba-tool dbcheck can now find and fix a missing or corrupted
- 'deleted objects' container.
- - BUG 11433: samba-dbcheck no longer offers to resort auxiliary class values
- in objectClass as these were then re-sorted at the next dbcheck indefinitely.
-
-Tombstone Reanimation
----------------------
-
-Samba now supports tombstone reanimation, a feature in the AD DC
-allowing tombstones, that is objects which have been deleted, to be
-restored with the original SID and GUID still in place.
-
-Multiple DNS Forwarders on the AD DC
-------------------------------------
-
-Multiple DNS forwarders are now supported on the AD DC, allowing
-samba to fall back between two different DNS servers for forwarded queries.
-
-Password quality plugin support in the AD DC
---------------------------------------------
-
-The check password script now operates correctly in the AD DC (this
-was silently ignored in past releases)
-
-pwdLastSet is now correctly honoured
-------------------------------------
-
-BUG 9654: the pwdLastSet attribute is now correctly handled (this previously
-permitted passwords that next expire).
-
-net ads dns unregister
-----------------------
-
-It is now possible to remove the DNS entries created with 'net ads register'
-with the matching 'net ads unregister' command.
-
-Samba-tool improvements
-------------------------
-
-Running samba-tool on the command line should now be a lot snappier. The tool
-now only loads the code specific to the subcommand that you wish to run.
-
-SMB 2.1 Leases enabled by default
----------------------------------
-
-Leasing is an SMB 2.1 (and higher) feature which allows clients to
-aggressively cache files locally above and beyond the caching allowed
-by SMB 1 oplocks. This feature was disabled in previous releases, but
-the SMB2 leasing code is now considered mature and stable enough to be
-enabled by default.
-
-Open File Description (OFD) Locks
----------------------------------
-
-On systems that support them (currently only Linux), the fileserver now
-uses Open File Description (OFD) locks instead of POSIX locks to implement
-client byte range locks. As these locks are associated with a specific
-file descriptor on a file this allows more efficient use when multiple
-descriptors having file locks are opened onto the same file. An internal
-tunable "smbd:force process locks = true" may be used to turn off OFD
-locks if there appear to be problems with them.
-
-Password sync as active directory domain controller
----------------------------------------------------
-
-The new commands 'samba-tool user getpassword'
-and 'samba-tool user syncpasswords' provide
-access and syncing of various password fields.
-
-If compiled with GPGME support (--with-gpgme) it's
-possible to store cleartext passwords in a PGP/OpenGPG
-encrypted form by configuring the new "password hash gpg key ids"
-option. This requires gpgme devel and python packages to be installed
-(e.g. libgpgme11-dev and python-gpgme on debian/ubuntu).
-
-Python crypto requirements
---------------------------
-
-Some samba-tool subcommands require python-crypto and/or
-python-m2crypto packages to be installed.
-
-SmartCard/PKINIT improvements
------------------------------
-
-"samba-tool user create" accepts --smartcard-required
-and "samba-tool user setpassword" accepts --smartcard-required
-and --clear-smartcard-required.
-
-Specifying --smartcard-required results in the UF_SMARTCARD_REQUIRED
-flags being set in the userAccountControl attribute.
-At the same time the account password is reset to a random
-NTHASH value.
-
-Interactive password logons are rejected, if the UF_SMARTCARD_REQUIRED
-bit is set in the userAccountControl attribute of a user.
-
-When doing a PKINIT based kerberos logon the KDC adds the
-required PAC_CREDENTIAL_INFO element to the authorization data.
-That means the NTHASH is shared between the PKINIT based client and
-the domain controller, which allows the client to do NTLM based
-authentication on behalf of the user. It also allows on offline
-logon using a smartcard to work on Windows clients.
-
-CTDB changes
-------------
-
-* New improved ctdb tool
-
- ctdb tool has been completely rewritten using new client API.
- Usage messages are much improved.
-
-* Sample CTDB configuration file is installed as ctdbd.conf.
-
-* The use of real-time scheduling when taking locks has been narrowed
- to limit potential performance impacts on nodes
-
-* CTDB_RECOVERY_LOCK now supports specification of an external helper
- to take and hold the recovery lock
-
- See the RECOVERY LOCK section in ctdb(7) for details. Documentation
- for writing helpers is provided in doc/cluster_mutex_helper.txt.
-
-* "ctdb natgwlist" has been replaced by a top level "ctdb natgw"
- command that has "master", "list" and "status" subcommands
-
-* The onnode command no longer supports the "recmaster", "lvs" and
- "natgw" node specifications
-
-* Faster resetting of TCP connections to public IP addresses during
- failover
-
-* Tunables MaxRedirectCount, ReclockPingPeriod,
- DeferredRebalanceOnNodeAdd are now obsolete/ignored
-
-* "ctdb listvars" now lists all variables, including the first one
-
-* "ctdb xpnn", "ctdb rebalanceip" and "ctdb rebalancenode" have been
- removed
-
- These are not needed because "ctdb reloadips" should do the correct
- rebalancing.
-
-* Output for the following commands has been simplified:
-
- ctdb getdbseqnum
- ctdb getdebug
- ctdb getmonmode
- ctdb getpid
- ctdb getreclock
- ctdb getpid
- ctdb pnn
-
- These now simply print the requested output with no preamble. This
- means that scripts no longer need to strip part of the output.
-
- "ctdb getreclock" now prints nothing when the recovery lock is not
- set.
-
-* Output for the following commands has been improved:
-
- ctdb setdebug
- ctdb uptime
-
-* "ctdb process-exists" has been updated to only take a PID argument
-
- The PNN can be specified with -n <PNN>. Output also cleaned up.
-
-* LVS support has been reworked - related commands and configuration
- variables have changed
-
- "ctdb lvsmaster" and "ctdb lvs" have been replaced by a top level
- "ctdb lvs" command that has "master", "list" and "status"
- subcommands.
-
- See the LVS sections in ctdb(7) and ctdbd.conf(5) for details,
- including configuration changes.
-
-* Improved sample NFS Ganesha call-out
-
-
