527 Release Notes for Samba 3.6.0
528 August 9, 2011
529 =============================
532 This is the first release of Samba 3.6.0.
534 Major enhancements in Samba 3.6.0 include:
537 Changed security defaults
538 -------------------------
540 Samba 3.6 has adopted a number of improved security defaults that will
541 impact on existing users of Samba.
543 client ntlmv2 auth = yes
544 client use spnego principal = no
545 send spnego principal = no
547 The impact of 'client ntlmv2 auth = yes' is that by default we will not
548 use NTLM authentication as a client. This applies to the Samba client
549 tools such as smbclient and winbind, but does not change the separately
550 released in-kernel CIFS client. To re-enable the poorer NTLM encryption
551 set '--option=clientusentlmv2auth=no' on your smbclient command line, or
552 set 'client ntlmv2 auth = no' in your smb.conf
554 The impact of 'client use spnego principal = no' is that Samba will
555 use CIFS/hostname to obtain a kerberos ticket, acting more like
556 Windows when using Kerberos against a CIFS server in smbclient,
557 winbind and other Samba client tools. This will change which servers
558 we will successfully negotiate kerberos connections to. This is due
559 to Samba no longer trusting a server-provided hint which is not
560 available from Windows 2008 or later. For correct operation with all
561 clients, all aliases for a server should be recorded as a as a
562 servicePrincipalName on the server's record in AD. (For this reason,
563 this behavior change and parameter was also made in Samba 3.5.9)
565 The impact of 'send spnego principal = no' is to match Windows 2008 and
566 not to send this principal, making existing clients give more consistent
567 behaviour (more likely to fall back to NTLMSSP) between Samba and
568 Windows 2008, and between Windows versions that did and no longer use
569 this insecure hint.
572 SMB2 support
573 ------------
575 SMB2 support in 3.6.0 is fully functional (with one omission),
576 and can be enabled by setting:
578 max protocol = SMB2
580 in the [global] section of your smb.conf and re-starting
581 Samba. All features should work over SMB2 except the modification
582 of user quotas using the Windows quota management tools.
584 As this is the first release containing what we consider
585 to be a fully featured SMB2 protocol, we are not enabling
586 this by default, but encourage users to enable SMB2 and
587 test it. Once we have enough confirmation from Samba
588 users and OEMs that SMB2 support is stable in wide user
589 testing we will enable SMB2 by default in a future Samba
590 release.
593 Internal Winbind passdb changes
594 -------------------------------
596 Winbind has been changed to use the internal samr and lsa rpc pipe to get
597 local user and group information instead of calling passdb functions. The
598 reason is to use more of our infrastructure and test this infrastructure by
599 using it. With this approach more code in Winbind is shared.
602 New Spoolss code
603 ----------------
605 The spoolss and the old RAP printing code have been completely
606 overhauled and refactored.
608 All calls from lanman/printing code has been changed to go through the
609 spoolss RPC interfaces, this allows us to keep all checks in one place
610 and avoid special cases in the main printing code.
611 Printing code has been therefore confined within the spoolss code.
613 All the printing code, including the spoolss RPC interfaces has been
614 changed to use the winreg RPC interfaces to store all data.
615 All data has been migrated from custom, arbitrary TDB files to the
616 registry interface. This transition allow us to present correct data to
617 windows client accessing the server registry through the winreg RPC
618 interfaces to query for printer data. Data is served out from a real
619 registry implementation and therefore arguably 100% forward compatible.
621 Migration code from the previous TDB files formats is provided. This
622 code is automatically invoked the first time the new code is run on the
623 server. Although manual migration is also available using the 'net
624 printer migrate' command.
626 These changes not only make all the spoolss code much more closer to
627 "the spec", it also greatly improves our internal testing of both
628 spoolss and winreg interfaces, and reduces overall code duplication.
630 As part of this work, new tests have been also added to increase
631 coverage.
633 This code will also allow, in future, an easy transition to split out
634 the spooling functions into a separate daemon for those OEMs that do not
635 need printing functionality in their appliances, reducing the code
636 footprint.
639 ID Mapping Changes
640 ------------------
642 The id mapping configuration has been a source of much grief in the past.
643 For this release, id mapping has been rewritten yet again with the goal
644 of making the configuration more simple and more coherent while keeping
645 the needed flexibility and even adding to the flexibility in some respects.
647 The major change that implies the configuration simplifications is at
648 the heart of the id mapping system: The separation of the "idmap alloc
649 system" that is responsible for the unix id counters in the tdb, tdb2
650 and ldap idmap backends from the id mapping code itself has been removed.
651 The sids_to_unixids operation is now atomic and encapsulates (if needed)
652 the action of allocating a unix id for a mapping that is to be created.
653 Consequently all idmap alloc configuration parameters have vanished and
654 it is hence now also not possible any more to specify an idmap alloc
655 backend different from the idmap backend. Each idmap backend uses its
656 own idmap unixid creation mechanism transparently.
658 As a consequence of the id mapping changes, the methods that are used
659 for storing and deleting id mappings have been removed from the winbindd
660 API. The "net idmap dump/restore" commands have been rewritten to
661 not speak through winbindd any more but directly act on the databases.
662 This is currently available for the tdb and tdb2 backends, the implementation
663 for ldap still missing.
665 The allocate_id functionality is preserved for the unix id creator of the
666 default idmap configuration is also used as the source of unix ids
667 for the group mapping database and for the posix attributes in a
668 ldapsam:editposix setup.
670 As part of the changes, the default idmap configuration has been
671 changed to be more coherent with the per-domain configuration.
672 The parameters "idmap uid", "idmap gid" and "idmap range" are now
673 deprecated in favour of the systematic "idmap config * : range"
674 and "idmap config * : backend" parameters. The reason for this change
675 is that the old options only provided an incomplete and hence deceiving
676 backwards compatibility, which was a source of many problems with
677 upgrades. By introducing this change in configuration, it should be
678 brought to the conciousness of the users that even the simple
679 id mapping is not working exactly as in Samba 3.0 versions any more.
682 Endpoint Mapper
683 ---------------
685 As Microsoft is more and more relying on endpoint mapper and we didn't have a
686 complete implementation we decided to create an instance for Samba. The
687 endpoint mapper is like a DNS server but for ports. If you want to talk to a
688 certain RPC service over TCP/IP, you just ask the endpoint mapper on which
689 port it is running. Then you can connect to the service and make sure that it
690 is running.
692 The code is deactivated by default, because it needs more testing and it
693 doesn't scale yet. If you want to enable and test the endpoint mapper
694 you can set "rpc_server:epmapper = daemon" in the smb.conf file.
697 Internal restructuring
698 ----------------------
700 Ongoing internal restructuring for better separation of internal subsystem to
701 achieve a faster build, smaller binaries and cleaner dependencies for the samba3
702 waf build.
705 SMB Traffic Analyzer
706 --------------------
708 Added the new SMB Traffic Analyzer (SMBTA) VFS module protocol 2
709 featuring encryption, multiple arguments, and easier parseability. A new
710 tool 'smbta-util' has been created to control the encryption behaviour
711 of SMBTA. For compatibility, SMBTA by default operates on version 1.
712 There are programs consuming the data that the module sends.
714 More information can be found on
715 http://holger123.wordpress.com/smb-traffic-analyzer/
718 NFS quota backend on Linux
719 --------------------------
721 A new nfs quota backend for Linux has been added that is based
722 on the existing Solaris/FreeBSD implementation. This allows samba
723 to communicate correct diskfree information for nfs imports that
724 are re-exported as samba shares.
