+This is the first preview release of Samba 3.6. 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/.
-Major enhancements in Samba 3.4.0 include:
-Authentication Changes:
-o Changed the way smbd handles untrusted domain names given during user
- authentication
+Major enhancements in Samba 3.6.0 include:
+
+
+Changed security defaults
+-------------------------
+
+Samba 3.6 has adopted a number of improved security defaults that will
+impact on existing users of Samba.
+
+ client ntlmv2 auth = yes
+ client use spnego principal = no
+ send spnego principal = no
+
+The impact of 'client ntlmv2 auth = yes' is that by default we will not
+use NTLM authentication as a client. This applies to the Samba client
+tools such as smbclient and winbind, but does not change the separately
+released in-kernel CIFS client. To re-enable the poorer NTLM encryption
+set '--option=clientusentlmv2auth=no' on your smbclient command line, or
+set 'client ntlmv2 auth = no' in your smb.conf
+
+The impact of 'client use spnego principal = no' is that we may be able
+to use Kerberos to communicate with a server less often in smbclient,
+winbind and other Samba client tools. We may fall back to NTLMSSP in
+more situations where we would previously rely on the insecure
+indication from the 'NegProt' CIFS packet. This mostly occursed when
+connecting to a name alias not recorded as a servicePrincipalName for
+the server. This indication is not available from Windows 2008 or later
+in any case, and is not used by modern Windows clients, so this makes
+Samba's behaviour consistent with other clients and against all servers.
+
+The impact of 'send spnego principal = no' is to match Windows 2008 and
+not to send this principal, making existing clients give more consistent
+behaviour (more likely to fall back to NTLMSSP) between Samba and
+Windows 2008, and between Windows versions that did and no longer use
+this insecure hint.
+
+
+SMB2 support
+------------
+
+SMB2 support in 3.6.0 is fully functional (with one omission),
+and can be enabled by setting:
+
+max protocol = SMB2
+
+in the [global] section of your smb.conf and re-starting
+Samba. All features should work over SMB2 except the modification
+of user quotas using the Windows quota management tools.
+
+As this is the first release containing what we consider
+to be a fully featured SMB2 protocol, we are not enabling
+this by default, but encourage users to enable SMB2 and
+test it. Once we have enough confirmation from Samba
+users and OEMs that SMB2 support is stable in wide user
+testing we will enable SMB2 by default in a future Samba
+release.
+
+
+Internal Winbind passdb changes
+-------------------------------
+
+Winbind has been changed to use the internal samr and lsa rpc pipe to get
+local user and group information instead of calling passdb functions. The
+reason is to use more of our infrastructure and test this infrastructure by
+using it. With this approach more code in Winbind is shared.
+
+
+New Spoolss code
+----------------
+
+The spoolss and the old RAP printing code have been completely
+overhauled and refactored.
+
+All calls from lanman/printing code has been changed to go through the
+spoolss RPC interfaces, this allows us to keep all checks in one place
+and avoid special cases in the main printing code.
+Printing code has been therefore confined within the spoolss code.
+
+All the printing code, including the spoolss RPC interfaces has been
+changed to use the winreg RPC interfaces to store all data.
+All data has been migrated from custom, arbitrary TDB files to the
+registry interface. This transition allow us to present correct data to
+windows client accessing the server registry through the winreg RPC
+interfaces to query for printer data. Data is served out from a real
+registry implementation and therefore arguably 100% forward compatible.
+
+Migration code from the previous TDB files formats is provided. This
+code is automatically invoked the first time the new code is run on the
+server. Although manual migration is also available using the 'net
+printer migrate' command.
+
+These changes not only make all the spoolss code much more closer to
+"the spec", it also greatly improves our internal testing of both
+spoolss and winreg interfaces, and reduces overall code duplication.
+
+As part of this work, new tests have been also added to increase
+coverage.
+
+This code will also allow, in future, an easy transition to split out
+the spooling functions into a separate daemon for those OEMs that do not
+need printing functionality in their appliances, reducing the code
+footprint.
+
+
+SMB Traffic Analyzer
+--------------------
+
+Added the new SMB Traffic Analyzer (SMBTA) VFS module protocol 2
+featuring encryption, multiple arguments, and easier parseability. A new
+tool 'smbta-util' has been created to control the encryption behaviour
+of SMBTA. For compatibility, SMBTA by default operates on version 1.
+There are programs consuming the data that the module sends.
+
+More information can be found on
+http://holger123.wordpress.com/smb-traffic-analyzer/
+
+
+NFS quota backend on Linux
+--------------------------
+
+A new nfs quota backend for Linux has been added that is based
+on the existing Solaris/FreeBSD implementation. This allows samba
+to communicate correct diskfree information for nfs imports that
+are re-exported as samba shares.

+Changes

+
+smb.conf changes
+----------------
-Authentication Changes
-======================
+ Parameter Name Description Default
+ -------------- ----------- -------
-Previously, when Samba was a domain member and a client was connecting using an
-untrusted domain name, such as BOGUS\user smbd would remap the untrusted
-domain to the primary domain smbd was a member of and attempt authentication
-using that DOMAIN\user name. This differed from how a Windows member server
-would behave. Now, smbd will replace the BOGUS name with it's SAM name. In
-the case where smbd is acting as a PDC this will be DOMAIN\user. In the case
-where smbd is acting as a domain member server this will be WORKSTATION\user.
-Thus, smbd will never assume that an incoming user name which is not qualified
-with the same primary domain, is part of smbd's primary domain.
+ async smb echo handler New No
+ client ntlmv2 auth Changed Default Yes
+ client use spnego principal New No
+ ctdb locktime warn threshold New 0
+ idmap alloc backend Removed
+ idmap read only New No
+ log writeable files on exit New No
+ multicast dns register New Yes
+ ncalrpc dir New
+ send spnego principal New No
+ smb2 max credits New 128
+ smb2 max read New 1048576
+ smb2 max trans New 1048576
+ smb2 max write New 1048576
+ strict allocate Changed Default Yes
+ username map cache time New 0
+ winbind max clients New 200
-While this behavior matches Windows, it may break some workflows which depended
-on smbd to always pass through bogus names to the DC for verification. A new
-parameter "map untrusted to domain" can be enabled to revert to the legacy
-behavior.
