- WHATS NEW IN Samba 3.0.0 RC2
- August 28 2003
- ==============================
+ WHATS NEW IN Samba 3 SVN
+ ========================
-This is the second release candidate snapshot of Samba 3.0.0. A release
-candidate implies that the code is very close to a final release, remember
-that this is still a non-production release intended for testing purposes.
-Use at your own risk.
-
-The purpose of this release candidate is to get wider testing of the major
-new pieces of code in the current Samba 3.0 development tree.
-Please refer to the section on "Known Issues" for more details.
-
-
-Major new features:
--------------------
-
-1) Active Directory support. Samba 3.0 is now able to
- join a ADS realm as a member server and authenticate
- users using LDAP/Kerberos.
-
-2) Unicode support. Samba will now negotiate UNICODE on the wire and
- internally there is now a much better infrastructure for multi-byte
- and UNICODE character sets.
-
-3) New authentication system. The internal authentication system has
- been almost completely rewritten. Most of the changes are internal,
- but the new auth system is also very configurable.
-
-4) New default filename mangling system.
-
-5) A new "net" command has been added. It is somewhat similar to
- the "net" command in windows. Eventually we plan to replace
- numerous other utilities (such as smbpasswd) with subcommands
- in "net".
-
-6) Samba now negotiates NT-style status32 codes on the wire. This
- improves error handling a lot.
-
-7) Better Windows 2000/XP/2003 printing support including publishing
- printer attributes in active directory.
-
-8) New loadable RPC modules.
-
-9) New default dual-daemon winbindd support for better performance.
-
-10) Support for migrating from a Windows NT 4.0 domain to a Samba
- domain and maintaining user, group and domain SIDs.
-
-11) Support for establishing trust relationships with Windows NT 4.0
- domain controllers.
-
-12) Initial support for a distributed Winbind architecture using
- an LDAP directory for storing SID to uid/gid mappings.
-
-13) Major updates to the Samba documentation tree.
-
-14) Full support for client and server SMB signing to ensure
- compatibility with default Windows 2003 security settings.
-
-Plus lots of other improvements!
-
-
-Additional Documentation
-------------------------
-
-Please refer to Samba documentation tree (included in the docs/
-subdirectory) for extensive explanations of installing, configuring
-and maintaining Samba 3.0 servers and clients. It is advised to
-begin with the Samba-HOWTO-Collection for overviews and specific
-tasks (the current book is up to approximately 400 pages) and to
-refer to the various man pages for information on individual options.

-######################################################################
-Upgrading from a previous Samba 3.0 beta
-########################################
-
-Beginning with Samba 3.0.0beta3, the RID allocation functions
-have been moved into winbindd. Previously these were handled
-by each passdb backend. This means that winbindd must be running
-to automatically allocate RIDs for users and/or groups. Otherwise,
-smbd will use the 2.2 algorithm for generating new RIDs.
-
-If you are using 'passdb backend = tdbsam' with a previous Samba
-3.0 beta release (or possibly alpha), it may be necessary to
-move the RID_COUNTER entry from /usr/local/samba/private/passdb.tdb
-to winbindd_idmap.tdb. To do this:
-
-1) Ensure that winbindd_idmap.tdb exists (launch winbindd at least
- once)
-2) build tdbtool by executing 'make tdbtool' in the source/tdb/
- directory
-3) run: (note that 'tdb>' is the tool's prompt for input)
-
- root# ./tdbtool /usr/local/samba/private/passdb.tdb
- tdb> show RID_COUNTER
- key 12 bytes
- RID_COUNTER
- data 4 bytes
- [000] 0A 52 00 00 .R.
-
- tdb> move RID_COUNTER /usr/local/samba/var/locks/winbindd_idmap.tdb
- ....
- record moved
-
-If you are using 'passdb backend = ldapsam', it will be necessary to
-store idmap entries in the LDAP directory as well (i.e. idmap backend
-= ldap). Refer to the 'net idmap' command for more information on
-migrating SID<->UNIX id mappings from one backend to another.
-
-If the RID_COUNTER record does not exist, then these instructions are
-unneccessary and the new RID_COUNTER record will be correctly generated
-if needed.

-Databases
----------
-
-This section contains brief descriptions of any new databases

-${lock directory}/*tdb before upgrading to Samba 3.0. Samba will
-upgrade databases as they are opened (if necessary), but downgrading
-from 3.0 to 2.2 is an unsupported path.
-
-Name Description Backup?
----- ----------- -------
-account_policy User policy settings yes
-gencache Generic caching db no
-group_mapping Mapping table from Windows yes
- groups/SID to unix groups
-winbindd_idmap ID map table from SIDS to UNIX yes
- uids/gids.
-namecache Name resolution cache entries no
-netsamlogon_cache Cache of NET_USER_INFO_3 structure no
- returned as part of a successful
- net_sam_logon request
-printing/*.tdb Cached output from 'lpq no
- command' created on a per print
- service basis
-registry Read-only samba registry skeleton no
- that provides support for exporting
- various db tables via the winreg RPCs
-
-
-Changes in Behavior
--------------------
-
-The following issues are known changes in behavior between Samba 2.2 and
-Samba 3.0 that may affect certain installations of Samba.
-
- 1) When operating as a member of a Windows domain, Samba 2.2 would
- map any users authenticated by the remote DC to the 'guest account'
- if a uid could not be obtained via the getpwnam() call. Samba 3.0
- rejects the connection as NT_STATUS_LOGON_FAILURE. There is no
- current work around to re-establish the 2.2 behavior.
-
- 2) When adding machines to a Samba 2.2 controlled domain, the
- 'add user script' was used to create the UNIX identity of the
- machine trust account. Samba 3.0 introduces a new 'add machine
- script' that must be specified for this purpose. Samba 3.0 will
- not fall back to using the 'add user script' in the absence of
- an 'add machine script'
-
-
-######################################################################
-Passdb Backends and Authentication
-##################################
-
-There have been a few new changes that Samba administrators should be
-aware of when moving to Samba 3.0.
-
- 1) encrypted passwords have been enabled by default in order to
- inter-operate better with out-of-the-box Windows client
- installations. This does mean that either (a) a samba account
- must be created for each user, or (b) 'encrypt passwords = no'
- must be explicitly defined in smb.conf.
-
- 2) Inclusion of new 'security = ads' option for integration
- with an Active Directory domain using the native Windows
- Kerberos 5 and LDAP protocols.
-
- MIT kerberos 1.3.1 supports the ARCFOUR-HMAC-MD5 encryption
- type which is neccessary for servers on which the
- administrator password has not been changed, or kerberos-enabled
- SMB connections to servers that require Kerberos SMB signing.
- Besides this one difference, either MIT or Heimdal Kerberos
- distributions are usable by Samba 3.0.
-
-
-Samba 3.0 also includes the possibility of setting up chains
-of authentication methods (auth methods) and account storage
-backends (passdb backend). Please refer to the smb.conf(5)
-man page for details. While both parameters assume sane default
-values, it is likely that you will need to understand what the
-values actually mean in order to ensure Samba operates correctly.
-
-The recommended passdb backends at this time are
-
- * smbpasswd - 2.2 compatible flat file format
- * tdbsam - attribute rich database intended as an smbpasswd
- replacement for stand alone servers
- * ldapsam - attribute rich account storage and retrieval
- backend utilizing an LDAP directory.
- * ldapsam_compat - a 2.2 backward compatible LDAP account
- backend
-
-Certain functions of the smbpasswd(8) tool have been split between the
-new smbpasswd(8) utility, the net(8) tool, and the new pdbedit(8)
-utility. See the respective man pages for details.

-LDAP
-####
-
-This section outlines the new features affecting Samba / LDAP
-integration.
-
-New Schema
-----------
-
-A new object class (sambaSamAccount) has been introduced to replace
-the old sambaAccount. This change aids us in the renaming of attributes
-to prevent clashes with attributes from other vendors. There is a
-conversion script (examples/LDAP/convertSambaAccount) to modify and LDIF
-file to the new schema.
-
-Example:
-
- $ ldapsearch .... -b "ou=people,dc=..." > old.ldif
- $ convertSambaAccount <DOM SID> old.ldif new.ldif
-
-The <DOM SID> can be obtained by running 'net getlocalsid <DOMAINNAME>'
-on the Samba PDC as root.
-
-The old sambaAccount schema may still be used by specifying the
-"ldapsam_compat" passdb backend. However, the sambaAccount and
-associated attributes have been moved to the historical section of
-the schema file and must be uncommented before use if needed.
-The 2.2 object class declaration for a sambaAccount has not changed
-in the 3.0 samba.schema file.
-
-Other new object classes and their uses include:
-
- * sambaDomain - domain information used to allocate rids
- for users and groups as necessary. The attributes are added
- in 'ldap suffix' directory entry automatically if
- an idmap uid/gid range has been set and the 'ldapsam'
- passdb backend has been selected.
-
- * sambaGroupMapping - an object representing the
- relationship between a posixGroup and a Windows
- group/SID. These entries are stored in the 'ldap
- group suffix' and managed by the 'net groupmap' command.
-
- * sambaUnixIdPool - created in the 'ldap idmap suffix' entry
- automatically and contains the next available 'idmap uid' and
- 'idmap gid'
-
- * sambaIdmapEntry - object storing a mapping between a
- SID and a UNIX uid/gid. These objects are created by the
- idmap_ldap module as needed.
-
- * sambaSidEntry - object representing a SID alone, as a Structural
- class on which to build the sambaIdmapEntry.
-
-
-New Suffix for Searching
-------------------------
-
-The following new smb.conf parameters have been added to aid in directing
-certain LDAP queries when 'passdb backend = ldapsam://...' has been
-specified.
-
- * ldap suffix - used to search for user and computer accounts
- * ldap user suffix - used to store user accounts
- * ldap machine suffix - used to store machine trust accounts
- * ldap group suffix - location of posixGroup/sambaGroupMapping entries
- * ldap idmap suffix - location of sambaIdmapEntry objects
-
-If an 'ldap suffix' is defined, it will be appended to all of the
-remaining sub-suffix parameters. In this case, the order of the suffix
-listings in smb.conf is important. Always place the 'ldap suffix' first
-in the list.
-
-Due to a limitation in Samba's smb.conf parsing, you should not surround
-the DN's with quotation marks.
-
-
-IdMap LDAP support
-------------------
-
-Samba 3.0 supports an ldap backend for the idmap subsystem. The
-following options would inform Samba that the idmap table should be
-stored on the directory server onterose in the "ou=idmap,dc=plainjoe,
-dc=org" partition.
-
- [global]
- ...
- idmap backend = ldap:ldap://onterose/
- ldap idmap suffix = ou=idmap,dc=plainjoe,dc=org
- idmap uid = 40000-50000
- idmap gid = 40000-50000
-
-This configuration allows winbind installations on multiple servers to
-share a uid/gid number space, thus avoiding the interoperability problems
-with NFS that were present in Samba 2.2.
-
-
-
-######################################################################
-Trust Relationships and a Samba Domain
-######################################
-
-Samba 3.0.0beta2 is able to utilize winbindd as the means of
-allocating uids and gids to trusted users and groups. More
-information regarding Samba's support for establishing trust
-relationships can be found in the Samba-HOWTO-Collection included
-in the docs/ directory of this release.
-
-First create your Samba PDC and ensure that everything is
-working correctly before moving on the trusts.
-
-To establish Samba as the trusting domain (named SAMBA) from a Windows NT
-4.0 domain named WINDOWS:
-
- 1) create the trust account for SAMBA in "User Manager for Domains"
- 2) connect the trust from the Samba domain using
- 'net rpc trustdom establish GLASS'
-
-To create a trustlationship with SAMBA as the trusted domain:
-
- 1) create the initial trust account for GLASS using
- 'smbpasswd -a -i GLASS'. You may need to create a UNIX
- account for GLASS$ prior to this step (depending on your
- local configuration).
- 2) connect the trust from a WINDOWS DC using "User Manager
- for Domains"
-
-Now join winbindd on the Samba PDC to the SAMBA domain using
-the normal steps for adding a Samba server to an NT4 domain:
-(note that smbd & nmbd must be running at this point)
-
- root# net rpc join -U root
- Password: <enter root password from smbpasswd file here>
-
-Start winbindd and test the join with 'wbinfo -t'.
-
-Now test the trust relationship by connecting to the SAMBA DC
-(e.g. POGO) as a user from the WINDOWS domain:
-
- $ smbclient //pogo/netlogon -U Administrator -W WINDOWS
- Password:
-
-Now connect to the WINDOWS DC (e.g. CRYSTAL) as a Samba user:
-
- $ smbclient //crystal/netlogon -U root -W WINDOWS
- Password:

-######################################################################
-Changes in Winbind
-##################
-
-Beginning with Samba3.0.0beta3, winbindd has been given new account
-manage functionality equivalent to the 'add user script' family of
-smb.conf parameters. The idmap design has also been changed to
-centralize control of foreign SID lookups and matching to UNIX
-uids and gids.
-
-
-Brief Description of Changes
-----------------------------
-
-1) The sid_to_uid() family of functions (smbd/uid.c) have been
- reverted to the 2.2.x design. This means that when resolving a
- SID to a UID or similar mapping:
-
- a) First consult winbindd
- b) perform a local lookup only if winbindd fails to
- return a successful answer
-
- There are some variations to this, but these two rules generally
- apply.
-
-2) All idmap lookups have been moved into winbindd. This means that
- a server must run winbindd (and support NSS) in order to achieve
- any mappings of SID to dynamically allocated UNIX ids. This was
- a conscious design choice.
-
-3) New functions have been added to winbindd to emulate the 'add user
- script' family of smbd functions without requiring that external
- scripts be defined. This functionality is controlled by the 'winbind
- enable local accounts' smb.conf parameter (enabled by default).
-
- However, this account management functionality is only supported
- in a local tdb (winbindd_idmap.tdb). If these new UNIX accounts
- must be shared among multiple Samba servers (such as a PDC and BDCs),
- it will be necessary to define your own 'add user script', et. al.
- programs that place the accounts/groups in some form of directory
- such as NIS or LDAP. This requirement was deemed beyond the scope
- of winbind's account management functions. Solutions for
- distributing UNIX system information have been deployed and tested
- for many years. We saw no need to reinvent the wheel.
-
-4) A member of a Samba controlled domain running winbindd is now able
- to map domain users directly onto existing UNIX accounts while still
- automatically creating accounts for trusted users and groups. This
- behavior is controlled by the 'winbind trusted domains only' smb.conf
- parameter (disabled by default to provide 2.2.x winbind behavior).
-
-5) Group mapping support is wrapped in the local_XX_to_XX() functions
- in smbd/uid.c. The reason that group mappings are not included
- in winbindd is because the purpose of Samba's group map is to
- match any Windows SID with an existing UNIX group. These UNIX
- groups can be created by winbindd (see next section), but the
- SID<->gid mapping is retreived by smbd, not winbindd.
-
-
-Examples
---------
-
-* security = server running winbindd to allocate accounts on demand
-
-* Samba PDC running winbindd to handle the automatic creation of UNIX
- identities for machine trust accounts
-
-* Automtically creating UNIX user and groups when migrating a Windows NT
- 4.0 PDC to a Samba PDC. Winbindd must be running when executing
- 'net rpc vampire' for this to work.

-Known Issues
-############
-
-* The smbldap perl scripts for managing user entries in an LDAP
- directory have not be updated to function with the Samba 3.0
- schema changes. This (or an equivalent solution) work is planned
- to be completed prior to the stable 3.0.0 release.
