UPGRADING
Users upgrading from Samba 3.x domain controllers and wanting to use
Samba 4.0 as an AD DC should use the 'samba-tool domain
classicupgrade' command. See the wiki for more details:
-https://wiki.samba.org/index.php/Samba4/samba3upgrade/HOWTO
+https://wiki.samba.org/index.php/Samba4/samba3upgrade/HOWTO
Users upgrading from Samba 4.0 alpha and beta releases since alpha15
should run 'samba-tool dbcheck --cross-ncs --fix' before re-starting
provision. This will set an underlying POSIX ACL if required (eg not
using the NTVFS file server).
+If you used the BIND9_FLATFILE or BIND9_DLZ features,
+you'll have to add '-dns' to the 'server services' option,
+as the internal dns server (SAMBA_INTERNAL) is the default now.

NEW FEATURES

issue.

-As DNS is an integral part of Active Directory, we also provide a DNS

-During the provision, a configuration file will be generated for bind

-minimal internal DNS server from within the Samba process, for easier
-'out of the box' configuration. Note however that this is not yet

To provide accurate timestamps to Windows clients, we integrate with
the NTP project to provide secured NTP replies. To use you need to

Some major user-visible changes include:
-- A fix for a segfault/abort on startup of the 'samba' binary in the
- credentials_secrets code.
-
-- A fix for samba-tool classicupgrade of pdb_ldap-based domains
-
-- A fix for samba-tool domain exportkeyab only exporting DES keys
-
-- Printing is now enabled on the AD DC
-
-- Fix bug #9124 - Samba fails to set "inherited" bit on inherited ACE's.
-
-- We now avoid printing secret attributes (such as unicodePwd and
- suppliementalCredentials) in ldb trace logs
-
-- s3-printing: fix bug 9123 lprng job tracking errors
-
-- A fix for building with MIT Kerberos
+- The smbd file server now offers SMB3 as the maximum protocol
+ by default. Samba can negotiate version 3 of the SMB protocol
+ and supports the required features, including all required
+ features of SMB 2.1 and SMB 2.0. Note that this does not imply
+ that Samba implements all features of SMB3 since many of them
+ are optional capabilities. Examples of features that Samba does
+ not implement yet are leases (SMB 2.1) and multi-channel (SMB 3).
+
+ Samba now offers an initial support for SMB2 durable file handles.
+ These are enabled by default and can be turned off on a per share
+ basis by setting "durable handles = no" on the share configuration.
+ Note that in order to prevent conflicts with other applications
+ accessing the same files, durable handles are only granted on
+ shares that are configured for CIFS/SMB2-only access, i.e. more
+ explicitly shares that are configured for minimal interoperability
+ with these settings:
+
+ kernel oplocks = no
+ kernel share modes = no
+ posix locking = no
+
+ The option "kernel share modes" has been introduced to be able
+ to turn the translation of SMB share modes into kernel flocks
+ off.
+
+- The 'provision' script was merged into 'samba-tool'
+ as 'samba-tool domain provision' the arguments are still
+ the same.
+
+- The 'updateprovision' script was renamed to 'samba_upgradeprovision'.
+
+- We changed the default dns implementation to the internal dns server
+ (SAMBA_INTERNAL). BIND9_FLATFILE and BIND9_DLZ are still available,
+ but you'll have to add '-dns' to the 'server services' option
+ to disable the internal dns server.
+ The default for 'allow dns updates' has changed to 'secure only'.
