Release Notes for Samba 3.0.6
|
|
Aug 19, 2004
|
|
=============================
|
|
|
|
This is the latest stable release of Samba. This is the version
|
|
that production Samba servers should be running for all
|
|
current bug-fixes. There have been several issues fixes since
|
|
the 3.0.4/5 release and new features have been added as well.
|
|
See the "Changes" section for details on exact updates.
|
|
|
|
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.

|
|
feature.
|
|
* Correctly honor the info level parameter in 'rpcclient
|
|
enumprinters'.
|
|
* Reintroduce 'force unknown acl user' parameter. When getting a
|
|
security descriptor for a file, if the owner sid is not known,
|
|
the owner uid is set to the current uid. Same for group sid.
|
|
* Ensure that REG_SZ values in the SetPrinterData actually
|
|
get written in UNICODE strings rather than ASCII.
|
|
* Ensure that the last kerberos error return is not invalid.

|
|
and an explicit configure --libdir setting.
|
|
|
|
|
|
o <kawasa_r@itg.hitachi.co.jp>
|
|
* Correct more memory leaks and initialization bugs.
|

|
|
the NT security editor.

|
|
* Fix DOS error code bug in reply_chkpath().
|

|
cli_samr_enum_als_groups; it is more like an account_control
|
|
field with individual bits what to retrieve.
|
|
* Implement 'net rpc group rename' -- rename domain groups.
|
|
* Implement the 'cups server' option. This makes it possible
|
|
to have virtual smbd's connect to different cups daemons.
|
|
* Paranoia fixes when adding local aliases to a user's NT_TOKEN.
|
|
* Fix sid_to_gid() calls in winbindd to prevent loops.
|
|
* Ensure that local_sid_to_gid() sets the type of the group on
|
|
return.
|
|
* Make sure that the clients are given back the IP address to
|
|
which they connected in the case of a multi-homed host. Only
|
|
affects strings the spoolss printing replies.
|
|
* Fix the bad password lockout. This has not worked as pdb_ldap.c
|
|
did not ask for the modifyTimestamp attribute, so it could
|
|
not find it. Try not to regress by not putting that attrib
|
|
in the main list but append it manually for the relevant searches.
|
|
* Fix two memleaks in login_cache.c.
|
|
* fixes memory bloat when unmarshalling strings.

|
|
'read only' smb.conf option.

|
|
MAX_REF_DOMAINS) SIDs to fail.
|
|
* Allow the 'idmap backend' parameter to accept a list of
|
|
LDAP servers for failover purposes.
|
|
* Revert code in smbd to remove a tdb when it has become
|
|
corrupted.
|
|
* Add paranoid checks when mapping SIDs to a uid/gid to
|
|
ensure that the type is correct.
|
|
* Initial work on getting client support for sending mailslot
|
|
datagrams.
|
|

Release Notes for Samba 3.0.5
|
|
July 20, 2004
|
|
=============================
|
|
|
|
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.
|
|
|
|
######################## SECURITY RELEASE ########################
|
|
|
|
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.
|
|
|
|
-------------
|
|
CAN-2004-0600
|
|
-------------
|
|
|
|
Affected Versions: Samba 3.0.2 and later
|
|
|
|
The internal routine used by the Samba Web Administration
|
|
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.
|
|
|

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.

commits
|
|
-------
|
|
|
|
o Change the interface for init_unistr2 to not take a length
|
|
but a flags field. We were assuming that
|
|
2*strlen(mb_string) == length of ucs2-le string. (bug 480).
|
|
o Allow d_printf() to handle strings with escaped quotation
|
|
marks since the msg file includes the escape character (bug 489).

|
be done unconditionally (bug 550).
|
|
o Remove duplicate smbspool link on SWAT's front page (bug 541).

|
|
(e.g. smbpasswd command).

|
|
paths are validated the same way.

|
|
o Refuse to configure if --with-expsam=$BACKEND was used but no
|
|
libraries were found for $BACKEND.
|
|
o Move sysquotas autoconf tests to a separate file.
|

|
up value which just happens to be less than sizeof(fstring).
|

'winbind trusted domains only = yes' (bug 680).
|

|
|
suffix. It's not needed and provides inconsistent functionality
|
|
from the tdb backend.
|
|
o Patch to handle munged dial string for Windows 2000 TSE.
|
|
Thanks to Gaz de France, Direction de la Recherche, Service
|
|
Informatique Métier for their supporting this work by Aurelien

|
Degrémont <adegremont@idealx.com>.
|
|
o Correct the "smbldap_open: cannot access when not root error"
|
|
messages when looking up group information (bug 281).

|
|
This fixes the bug that prevented local users from
|
|
matching an AD user when not running winbindd (bug 698).
|
|
o Fix a problem with configure on *BSD systems. Make sure
|
|
we add -liconv etc to LDFLAGS.

|
|
server goes away.

|
|
(bug 590).
|
|

|
|
monitor used by Windows NT and later clients (bug 660).
|
|
o Fix several reported problems with point-n-print from
|
|
Windows 2000/XP clients due to a bug in the EnumPrinterDataEx()
|
|
reply (bug 338, 527 & 643).
|
|
o Fix a handful of potential memory leaks in the LDAP code used
|
|
by ldapsam[_compat] and the LDAP idmap backend.
|
|
o Fix for pdbedit error code returns (bug 763).
|
|
o Make sure we only enumerate group mapping entries (not
|
|
/etc/group) even when doing local aliases.
|
|
o Relax check on the pipe name in a dce/rpc bind response to work
|
|
around issues with establishing trusts to a Windows 2003 domain.
|
|
o Ensure we mangle names ending in '.' in hash2 mangling method.
|
|
o Correct parsing issues with munged dial string.
|
|
o Fix bugs in quota support for XFS.
|
|
o Add a cleaner method for applications that need to provide
|
|
name->SID mappings to do this via NSS rather than having to
|
|
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).
|
|
o Fix renames across file systems.
|
|
o Ensure that items in a list of strings containing whitespace are
|
|
written out surrounded by single quotes. This means that both
|
|
double and single quotes are now used to surround strings in
|
|
smb.conf (bug 481).
|
|
o Enable SWAT to correctly determine if winbindd is running (bug
|

|
|
using CUPS (bug 467).

|
|
o Disable NTLM2 for RPC pipes.
|
|
o Allow the client to specify the NTLM2 flags got NTLMSSP
|
|
authentication.
|
|
o Change the name of the job passed off to cups from "Test Page"
|
|
to "smbprn.00000033 Test Page" so that we can get the smb
|
|
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.
|
|
o Retrieve the correct ACL group bits if the file has an ACL
|
|
(bug 802).
|
|
o Implement "net rpc group members": Get members of a domain group
|
|
in human-readable format.
|
|
o Add MacOSX (Darwin) specific charset module code.
|
|
o Use samr_dispinfo(level == 1) for enumerating domain users so we
|
|
can include the full name in gecos field (bug 587).
|
|
o Add support for winbind's NSS library on FeeeBSD 5.1 (bug 797).
|
|
o Implement 'net rpc group list [global|local|builtin]*' for a

|
|
o Don't mistake pre-existing UNIX jobs for smb jobs (remainder of
|
|
bug 770).
|
|
o Add 'Replicator' and 'RAS Servers' to list of builtin SIDs
|
|
(bug 608).
|
|
o Fix inverted logic in hosts allow/deny checks caused by
|
|
s/strcmp/strequal/ (bug 846).

|
|
o Fix typo in 'hash' mangling algorithm.
|
|
o Support munged dial for ldapsam (bug 800).
|
|
o Fix process_incoming_data() to return the number of bytes handled
|
|
this call whether we have a complete PDU or not; fixes bug
|
|
with multiple PDU request rpc's broken over SMBwriteX calls
|
|
each.
|
|
o Fix incorrect smb flags2 for connections to pre-NT servers
|
|
(causes smbclient to fail to OS2 for example) (bug 821).

o Fix bugs in hosts allow/deny when using a mismatched
|
|
network/netmask pair.

|
|
is NULL (partial work on bug 687).

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.

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.
|
|
|
|

|
---- ----------- -------
|
|
account_policy User policy settings yes
|
|
gencache Generic caching db no
|
|
group_mapping Mapping table from Windows yes

|
|
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=<Domain SID> \
|
|
--input=sambaAcct.ldif --output=sambaSamAcct.ldif \
|
|
--changetype=[modify|add]
|
|
|
|
The <DOM SID> can be obtained by running 'net getlocalsid
|
|
<DOMAINNAME>' 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: <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.
