+Samba 4.0 beta8 is not a final Samba release, however we are now making
good progress towards a Samba 4.0 release. However, this is expected to be the
last beta release before we start on our release candidate series.
For pure file server work, the binaries users would expect from that
series (nmbd, winbindd, smbpasswd) continue to be available. When
running an AD DC, you only need to run 'samba' (not
-nmbd/smbd/winbind), as the required services are co-ordinated by this
+nmbd/smbd/winbind), as the required services are co-coordinated by this
master binary.
As DNS is an integral part of Active Directory, we also provide a DNS
Python programs to interface to Samba's internals, and many tools and
internal workings of the DC code is now implemented in python.

-CHANGES SINCE beta6
+CHANGES SINCE beta8
+===================
+
+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.

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
+- A fix for a segfault/abort on startup of the 'samba' binary in the
+ credentials_secrets code.
-- SMB3 encryption support
+- A fix for samba-tool classicupgrade of pdb_ldap-based domains
-- New 'samba-tool ntacl' commands:
- - samba-tool ntacl sysvolreset
- - samba-tool ntacl sysvolcheck
+- A fix for samba-tool domain exportkeyab only exporting DES keys
-Less visible, but important changes under the hood include:
+- Printing is now enabled on the AD DC
-- Continued work to support SMB2 and SMB3
+- Fix bug #9124 - Samba fails to set "inherited" bit on inherited ACE's.
-- Continued work to use async IO to improve file server performance.
+- We now avoid printing secret attributes (such as unicodePwd and
+ suppliementalCredentials) in ldb trace logs
-- Patches to ensure that talloc_tos() and talloc_stackframe() are
- always used correctly.
+- s3-printing: fix bug 9123 lprng job tracking errors
-- 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)
+- A fix for building with MIT Kerberos
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.
