Samba 3.0.11 Available for Download
==============================
Release Notes for Samba 3.0.11
Feb 5, 2005
==============================
This is the latest stable release of Samba. This is the version
that production Samba servers should be running for all current
bug-fixes. Please read the following important changes in this
release.
Common bugs fixed in 3.0.11 include:
o Crash in smbd when using CUPS printing.
o Parsing error of other SIDs included in the user_info_3
structure returned from domain controllers.
o Inefficiencies when searching non-AD LDAP directories.
o Failure to expand variables in user domain attributes
in tdbsam and ldapsam.
o Memory leaks.
o Failure to retrieve certain attribute when migrating from
a Windows DC to a Samba DC via 'net rpc vampire'.
o Numerous printing bugs bugs including memory
bloating on large/busy print servers.
o Compatibility issues with Exchange 5.5 SP4.
o sendfile fixes.
Additional features introduced in Samba 3.0.11:
o Winbindd performance improvements.
o More 'net rpc vampire' functionality.
o Support for the Windows privilege model to assign rights
to specific SIDs.
o New administrative options to the 'net rpc' command.
LDAP Changes
------------
If "ldap user suffix" or "ldap machine suffix" are defined in
smb.conf, all user-accounts must reside below the user suffix,
and all machine and inter-domain trust-accounts must be located
below the machine suffix. Previous Samba releases would fall
back to searching the 'ldap suffix' in some cases.
Privilege Model
---------------
Samba 3.0.11 supports the following assignable rights
SeMachineAccountPrivilege Add machines to domain
SePrintOperatorPrivilege Manage printers
SeAddUsersPrivilege Add users and groups to the domain
SeRemoteShutdownPrivilege Force shutdown from a remote system
SeDiskOperatorPrivilege Manage disk shares
These rights can be assigned to arbitrary users or groups
via the 'net rpc rights grant/revoke' command. More details
of Samba's privilege implementation can be found in the
Samba-HOWTO-Collection.

Release Notes for Samba 3.0.8
Nov 7, 2004
=============================
Common bugs fixed in 3.0.8 include:
o Compile fixes for HP-UX
o Fixes for the printer publishing code used when joined to
an AD domain.
o Incompatibilities with file system quotas.
o Several bugs in the spoolss printing code and print system
backends.
o Inconsistencies in the username map functionality when
configured on domain member servers.
o Various compile warnings and errors on various platforms.
o Fixes for kerberos interoperability with Windows 200x
domains when using DES keys.
o Fix for CAN-2004-0930 -- smbd remote DoS vulnerability.
o Fix for CAN-2004-0882 -- possible buffer overrun in smbd.
New features included in the 3.0.8 release are:
o New migration functionality added the the net tool
for files/directories, printers, and shares.
o New experimental idmap backend for assigning uids/gids
directly based on the user/group RID when acting as a
member of single domain without any trusts.
o Additional printer migration support for XP/2003 platforms.
Change in Winbindd Behavior
---------------------------
All usernames returned by winbindd are now converted to lower
case for better consistency. This means any winbind installation
relying on the winbind username will need to rename existing
directories and/or files based on the username (%u and %U) to lower
case (e.g. mv $name `echo $name | tr '[A-Z]' '[a-z]'`). This may
include mail spool files, home directories, valid user lines in
smb.conf, etc....
Change in Username Map
----------------------
Previous Samba releases would only support reading the fully qualified
username (e.g. DOMAIN\user) from the username map when performing a
kerberos login from a client. However, when looking up a map
entry for a user authenticated by NTLM[SSP], only the login name would be
used for matches. This resulted in inconsistent behavior sometimes
even on the same server.
Samba 3.0.8 obeys the following rules when applying the username
map functionality:
* When performing local authentication, the username map is
applied to the login name before attempting to authenticate
the connection.
* When relying upon a external domain controller for validating
authentication requests, smbd will apply the username map
to the fully qualified username (i.e. DOMAIN\user) only
after the user has been successfully authenticated.

=============================
Release Notes for Samba 3.0.6
Aug 19, 2004
=============================
Common bugs fixed in 3.0.6 include:
o Schannel failure in winbindd.
o Numerous memory leaks.
o Incompatibilities between the 'write list' and 'force user'
smb.conf options.
o Premature optimization of the open_directory() internal
function that broke tools such as the ArcServe backup
agent, Macromedia HomeSite, and Robocopy.
o Corrupt workgroup names in nmbd's browse.dat.
o Sharing violation errors commonly seen when opening
when serving Microsoft Office documents from a Samba
file share.
o Browsing problems caused by an apostrophe (') in the
computer's description field.
o Problems creating special file types from UNIX CIFS
clients and enabling 'unix extensions'.
o Fix stalls in smbd caused by inaccessible LDAP servers.
o Remove various memory leaks.
o Fix issues in the password lockout feature.
New features introduced in this release include:
O Support symlinks created by CIFS clients which
can be followed on the server.
o Using a cups server other than localhost.
o Maintaining the service principal entry in the system
keytab for integration with other kerberized services.
Please refer to the 'use kerberos keytab' entry in
smb.conf(5). When using the heimdal kerberos libraries,
you must also specify the following in /etc/krb5.conf:
[libdefaults]
default_keytab_name = FILE:/etc/krb5.keytab
o Support for maintaining individual printer names
stored separately from the printer's sharename.
o Support for maintaining user password history.
o Support for honoring the logon times for user in a
Samba domain.
--------------------------------------------
unix extensions = yes (default) and symlinks
--------------------------------------------
Beginning with Samba 3.0.6pre1 (formerly known as 3.0.5pre1),
clients supporting the UNIX extensions to the CIFS protocol
can create symlinks to absolute paths which will be **followed**
by the server. This functionality has been requested in order
to correctly support certain applications when the user's home
directory is mounted using some type of CIFS client (e.g. the
cifsvfs in the Linux 2.6 kernel).
If this behavior is not acceptable for your production environment
you can set 'wide links = no' in the specific share declaration in
the server's smb.conf. Be aware that disabling wide link support
out of a share in Samba may impact the server's performance due
to the fact that smbd will now have to check each path additional
times before traversing it.
------------------------
Password History Support
------------------------
The new password history feature allows smbd to check the new
password in password change requests against a list of the user's
previous passwords. The number of previous passwords to save can
be set using pdbedit (4 in this example):
root# pdbedit -P "password history" -C 4
When using the ldapsam passdb backend, it is vital to secure the
following attributes from access by non-administrative users:
* sambaNTPassword
* sambaLMPassword
* sambaPasswordHistory
You should refer to your directory server's documentation on how
to implement this restriction.
Changes since 3.0.5

=============================
Please note that Samba 3.0.5 is identical to Samba 3.0.4 with
the exception of correcting the two security issues outlined
below.

Summary: Multiple Potential Buffer Overruns in Samba 3.0.x
CVE ID: CAN-2004-0600, CAN-2004-0686
(http://cve.mitre.org/)
This is the latest stable release of Samba. This is the version
that production Samba servers should be running for all current
bug-fixes.
It has been confirmed that versions of Samba 3 prior to v3.0.4
are vulnerable to two potential buffer overruns. The individual
details are given below.

Affected Versions: Samba 3.0.2 and later

Tool (SWAT v3.0.2 and later) to decode the base64 data
during HTTP basic authentication is subject to a buffer
overrun caused by an invalid base64 character. It is
recommended that all Samba v3.0.2 or later installations
running SWAT either (a) upgrade to v3.0.5, or (b) disable
the swat administration service as a temporary workaround.
This same code is used internally to decode the
sambaMungedDial attribute value when using the ldapsam
passdb backend. While we do not believe that the base64
decoding routines used by the ldapsam passdb backend can
be exploited, sites using an LDAP directory service with
Samba are strongly encouraged to verify that the DIT only
allows write access to sambaSamAccount attributes by a
sufficiently authorized user.
The Samba Team would like to heartily thank Evgeny Demidov
for analyzing and reporting this bug.
-------------
CAN-2004-0686
-------------
Affected Versions: Samba 3.0.0 and later
A buffer overrun has been located in the code used to support
the 'mangling method = hash' smb.conf option. Please be aware
that the default setting for this parameter is 'mangling method
= hash2' and therefore not vulnerable.
Affected Samba 3 installations can avoid this possible security
bug by using the default hash2 mangling method. Server
installations requiring the hash mangling method are encouraged
to upgrade to Samba 3.0.5.

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.
o Make sure we don't append the 'ldap suffix' when writing out the
'ldap XXX suffix' values in SWAT (bug 328).

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'

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=
