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.

+CHANGES SINCE beta8

$ git clone git://git.samba.org/samba.git

+$ git log samba-4.0.0beta8..samba-4.0.0rc1
Some major user-visible changes include:
-- ACLs are now set during provision at the POSIX layer for the sysvol
- share. This allows group policies to be modified by Domain
- Administrators (Policy Administrators) that are not the actual
- Administrator user.
-
-- A number of verified fixes for expanding memory use across the AD
- domain controller, including in the Bind9 DLZ module.
-
-- A fix for bug #9097 (the winbind in the AD DC would lock up under
- parallel requests).
-
-- wbinfo --ping-dc now returns helpful information on what failed and
- against which DC it failed
-
-- SMB3 encryption support
-
-- New 'samba-tool ntacl' commands:
- - samba-tool ntacl sysvolreset
- - samba-tool ntacl sysvolcheck
-
-Less visible, but important changes under the hood include:
-
-- Continued work to support SMB2 and SMB3
-
-- Continued work to use async IO to improve file server performance.
-
-- Patches to ensure that talloc_tos() and talloc_stackframe() are
- always used correctly.
-
-- We can now test the implementation of NT -> POSIX ACL mapping in a
- unit test with VFS bindings exposing both to python. We also store
- the posix ACL in a tdb during make test, allowing testing of this
- feature on all platforms, regardless of local FS settings.
-
-- Python bindings for the source3 async libsmb library (for use in testing)
+- 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'.
KNOWN ISSUES
============
+- 'samba-tool domain classicupgrade' will fail when setting ACLs on
+ the GPO folders with NT_STATUS_INVALID_ONWER in the default
+ configuration. This happens if, as is typical a 'domain admins'
+ group (-512) is mapped in the passdb backend being upgraded. This
+ is because the group mapping to a GID only prevents Samba from
+ allocating a uid for that group. The uid is needed so the 'domain
+ admins' group can own the GPO file objects.
+
+ To work around this issue, remove the 'domain admins' group before
+ upgrade, as it will be re-created automatically. You will
+ of course need to fill in the group membership again. A future release
+ will make this automatic, or find some other workaround.
