Release Notes for Samba 3.0.2a
February 13, 2004
==============================
Samba 3.0.2a is a minor patch release for the 3.0.2 code base
to address, in particular, a problem when using pdbedit to
sanitize (--force-initialized-passwords) Samba's tdbsam
backend. This is the latest stable release of Samba. This
is the version that all production Samba servers should be
running for all current bug-fixes.
******************* Attention! Achtung! Kree! *********************
Beginning with Samba 3.0.2, passwords for accounts with a last
change time (LCT-XXX in smbpasswd, sambaPwdLastSet attribute in
ldapsam, etc...) of zero (0) will be regarded as uninitialized
strings. This will cause authentication to fail for such
accounts. If you have valid passwords that meet this criteria,
you must update the last change time to a non-zero value. If you
do not, then 'pdbedit --force-initialized-passwords' will disable
these accounts and reset the password hashes to a string of X's.
******************* Attention! Achtung! Kree! *********************
Changes since 3.0.2
-------------------
commits
-------
Please refer to the CVS log for the SAMBA_3_0 branch for complete
details. The list of changes per contributor are as follows:
o Jeremy Allison
* Added paranoia checks in parsing code.
o Andrew Bartlett
* Ensure that changes to uninitialized passwords in ldapsam
are written to the DIT.
o Gerald (Jerry) Carter
* Fixed iterator in tdbsam.
* Fix bug that disabled accounts with a valid NT password
hash, but no LanMan hash.
o Steve French
* Added missing nosetuid and noexec options.
o Bostjan Golob
* BUG 1046: Don't overwrite usernames of entries returned
by getpwent_list().
o Sebastian Krahmer
* Fixed potential crash bug in NTLMSSP parsing code.
o Tim Potter
* Fixed logic in tdb_brlock error checking.
o Urban Widmark
* Set nosuid,nodev flags in smbmnt by default.

Release Notes for Samba 3.0.2
February 9, 2004
=============================
It has been confirmed that previous versions of Samba 3.0 are
susceptible to a password initialization bug that could grant an
attacker unauthorized access to a user account created by the
mksmbpasswd.sh shell script.
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CAN-2004-0082 to this issue.
Samba administrators not wishing to upgrade to the current
version should download the 3.0.2 release, build the pdbedit
tool, and run
root# pdbedit-3.0.2 --force-initialized-passwords
This will disable all accounts not possessing a valid password
(e.g. the password field has been set a string of X's).
Samba servers running 3.0.2 are not vulnerable to this bug
regardless of whether or not pdbedit has been used to sanitize
the passdb backend.
Some of the more visible bugs in 3.0.1 addressed in the 3.0.2
release include:
o Joining a Samba domain from Pre-SP2 Windows 2000 clients.
o Logging onto a Samba domain from Windows XP clients.
o Problems with the %U and %u smb.conf variables in relation to
Windows 9x/ME clients.
o Kerberos failures due to an invalid in memory keytab detection
test.
o Updates to the ntlm_auth tool.
o Fixes for various SMB signing errors.
o Better separation of WINS and DNS queries for domain controllers.
o Issues with nss_winbind FreeBSD and Solaris.
o Several crash bugs in smbd and winbindd.
o Output formatting fixes for smbclient for better compatibility
with scripts based on the 2.2 version.

know the winbindd pipe protocol.
o Adds a variant of the winbindd_getgroups() call called
winbindd_getusersids() that provides direct SID->SIDs listing of
a users supplementary groups. This is enough to allow non-Samba
applications to do ACL checking.

jobid back. This allow users to delete jobs with cups printing
backend (partial work on bug 770).
o Fix build of winbindd with static pdb modules.

The original 3.0.0 release notes follow
=======================================
WHATS NEW IN Samba 3.0.0
September 24, 2003
=======================================
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 module support for passdb backends and character
sets.
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.
15) Improvement of ACL mapping features based on code donated by
Andreas Grünbacher.
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.
We are very glad to be able to include the second edition of
"Using Samba" by Jay Ts, Robert Eckstein, and David Collier-Brown
(O'Reilly & Associates) in this release. The book is available
on-line at http://samba.org/samba/docs/ and is included with
the Samba Web Administration Tool (SWAT). Thanks to the authors and
publisher for making "Using Samba" under the GNU Free Documentation
License.
######################################################################
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
introduced in Samba 3.0. Please remember to backup your existing
${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=..." > sambaAcct.ldif
$ convertSambaAccount --sid= \
--input=sambaAcct.ldif --output=sambaSamAcct.ldif \
--changetype=[modify|add]
The can be obtained by running 'net getlocalsid
' on the Samba PDC as root. The changetype determines
the format of the generated LDIF output--either create new entries
or modify existing entries.
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:
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.
