| 2 | Release Notes for Samba 3.0.2a |
|---|
| 3 | February 13, 2004 |
|---|
| 4 | ============================== |
|---|
| 5 | |
|---|
| 6 | Samba 3.0.2a is a minor patch release for the 3.0.2 code base |
|---|
| 7 | to address, in particular, a problem when using pdbedit to |
|---|
| 8 | sanitize (--force-initialized-passwords) Samba's tdbsam |
|---|
| 9 | backend. This is the latest stable release of Samba. This |
|---|
| 10 | is the version that all production Samba servers should be |
|---|
| 11 | running for all current bug-fixes. |
|---|
| 12 | |
|---|
| 13 | ******************* Attention! Achtung! Kree! ********************* |
|---|
| 14 | |
|---|
| 15 | Beginning with Samba 3.0.2, passwords for accounts with a last |
|---|
| 16 | change time (LCT-XXX in smbpasswd, sambaPwdLastSet attribute in |
|---|
| 17 | ldapsam, etc...) of zero (0) will be regarded as uninitialized |
|---|
| 18 | strings. This will cause authentication to fail for such |
|---|
| 19 | accounts. If you have valid passwords that meet this criteria, |
|---|
| 20 | you must update the last change time to a non-zero value. If you |
|---|
| 21 | do not, then 'pdbedit --force-initialized-passwords' will disable |
|---|
| 22 | these accounts and reset the password hashes to a string of X's. |

| 81 | ============================= |
|---|
| 82 | Release Notes for Samba 3.0.2 |
|---|
| 83 | February 9, 2004 |
|---|
| 84 | ============================= |
|---|
| 85 | |
|---|
| 86 | It has been confirmed that previous versions of Samba 3.0 are |
|---|
| 87 | susceptible to a password initialization bug that could grant an |
|---|
| 88 | attacker unauthorized access to a user account created by the |
|---|
| 89 | mksmbpasswd.sh shell script. |
|---|
| 90 | |
|---|
| 91 | The Common Vulnerabilities and Exposures project (cve.mitre.org) |
|---|
| 92 | has assigned the name CAN-2004-0082 to this issue. |
|---|
| 93 | |
|---|
| 94 | Samba administrators not wishing to upgrade to the current |
|---|
| 95 | version should download the 3.0.2 release, build the pdbedit |
|---|
| 96 | tool, and run |
|---|
| 97 | |
|---|
| 98 | root# pdbedit-3.0.2 --force-initialized-passwords |
|---|
| 99 | |
|---|
| 100 | This will disable all accounts not possessing a valid password |
|---|
| 101 | (e.g. the password field has been set a string of X's). |
|---|
| 102 | |
|---|
| 103 | Samba servers running 3.0.2 are not vulnerable to this bug |
|---|
| 104 | regardless of whether or not pdbedit has been used to sanitize |
|---|
| 105 | the passdb backend. |
|---|
| 106 | |
|---|
| 107 | Some of the more visible bugs in 3.0.1 addressed in the 3.0.2 |
|---|

|---|
| 113 | Windows 9x/ME clients. |
|---|
| 114 | o Kerberos failures due to an invalid in memory keytab detection |
|---|
| 115 | test. |
|---|
| 116 | o Updates to the ntlm_auth tool. |
|---|
| 117 | o Fixes for various SMB signing errors. |
|---|
| 118 | o Better separation of WINS and DNS queries for domain controllers. |
|---|
| 119 | o Issues with nss_winbind FreeBSD and Solaris. |
|---|
| 120 | o Several crash bugs in smbd and winbindd. |
|---|

|---|
| 122 | with scripts based on the 2.2 version. |

|---|
| 417 | |
|---|
| 418 | o Change the interface for init_unistr2 to not take a length |

|---|
| 458 | name for a user if he/she has one (bug 406). |
|---|
| 459 | o Fix up error code returns from Samba4 tester. Ensure invalid |

| 479 | non-C99 compliant implementations of snprintf(). |
|---|
| 480 | o Use @PICSUFFIX@ instead of .po in Makefile.in (bug 574). |
|---|
| 481 | o Make sure we break out of samsync loop on error. |
|---|
| 482 | o Ensure error code path doesn't free unmalloc()'d memory |
|---|
| 483 | (bug 628). |

|---|
| 516 | o New files for support of initshutdown pipe. Win2k doesn't |

| 539 | o Lowercase netgroups lookups (bug 703). |
|---|
| 540 | o Use the actual size of the buffer in strftime instead of a made |

| 550 | o Compile tdbdump by default. |
|---|
| 551 | o Apply patches to fix iconv detection for FreeBSD. |
|---|
| 552 | o Do not allow the 'guest account' to be added to a passdb backend |

|---|
| 556 | lookup fails (bug 698). |
|---|
| 557 | o Add const for lp_set_name_resolve_order() to avoid compiler |
|---|
| 558 | warnings (bug 471). |
|---|
| 559 | o Add support for the %i macro in smb.conf to stand in for the for |
|---|
| 560 | the local IP address to which a client connected. |
|---|
| 561 | o Allow winbindd to match local accounts to domain SID when |
|---|
| 562 | 'winbind trusted domains only = yes' (bug 680). |
|---|
| 563 | o Remove code in idmap_ldap that searches the user suffix and group |
|---|
| 564 | suffix. It's not needed and provides inconsistent functionality |
|---|
| 565 | from the tdb backend. |
|---|
| 566 | o Patch to handle munged dial string for Windows 200 TSE. |
|---|
| 567 | o Correct the "smbldap_open: cannot access when not root error" |
|---|
| 568 | messages when looking up group information (bug 281). |
|---|
| 569 | o Skip over the winbind separator when looking up a user. |
|---|
| 570 | This fixes the bug that prevented local users from |
|---|
| 571 | matching an AD user when not running winbindd (bug 698). |
|---|
| 572 | o Fix a problem with configure on *BSD systems. Make sure |
|---|
| 573 | we add -liconv etc to LDFLAGS. |
|---|
| 574 | o Fix core dump bug when "security = server" and the authentication |

| 579 | o Fix bug preventing print jobs from display in the queue |
|---|
| 580 | monitor used by Windows NT and later clients (bug 660). |
|---|
| 581 | o Fix several reported problems with point-n-print from |
|---|
| 582 | Windows 2000/XP clients due to a bug in the EnumPrinterDataEx() |
|---|
| 583 | reply (bug 338, 527 & 643). |
|---|
| 584 | o Fix a handful of potential memory leaks in the LDAP code used |
|---|
| 585 | by ldapsam[_compat] and the LDAP idmap backend. |
|---|
| 586 | o Fix for pdbedit error code returns (bug 763). |
|---|
| 587 | o Make sure we only enumerate group mapping entries (not |
|---|
| 588 | /etc/group) even when doing local aliases. |
|---|
| 589 | o Relax check on the pipe name in a dce/rpc bind response to work |
|---|
| 590 | around issues with establishing trusts to a Windows 2003 domain. |
|---|
| 591 | o Ensure we mangle names ending in '.' in hash2 mangling method. |
|---|
| 592 | o Correct parsing issues with munged dial string. |
|---|
| 593 | o Fix bugs in quota support for XFS. |
|---|
| 594 | o Add a cleaner method for applications that need to provide |
|---|
| 595 | name->SID mappings to do this via NSS rather than having to |
|---|
| 596 | know the winbindd pipe protocol. |
|---|
| 597 | o Adds a variant of the winbindd_getgroups() call called |
|---|
| 598 | winbindd_getusersids() that provides direct SID->SIDs listing of |
|---|
| 599 | a users supplementary groups. This is enough to allow non-Samba |
|---|
| 600 | applications to do ACL checking. |
|---|
| 601 | o Make sure we don't append the 'ldap suffix' when writing out the |
|---|
| 602 | 'ldap XXX suffix' values in SWAT (bug 328). |
|---|
| 603 | o Fix renames across file systems. |
|---|
| 604 | o Ensure that items in a list of strings containing whitespace are |
|---|
| 605 | written out surrounded by single quotes. This means that both |
|---|
| 606 | double and single quotes are now used to surround strings in |
|---|
| 607 | smb.conf (bug 481). |
|---|
| 608 | o Enable SWAT to correctly determine if winbindd is running (bug |
|---|
| 609 | 398). |
|---|
| 610 | o Include WWW-Authenticate field in 401 response for bad auth |
|---|
| 611 | attempt (bug 629). |
|---|
| 612 | o Add support for NTLM2 (NTLMv2 session security). |
|---|
| 613 | o Add support for variable-length session keys. |
|---|
| 614 | o More privilege fixes for group enumeration in LDAP (bug 281). |
|---|
| 615 | o Use the dns name (or IP) as the originating client name when |
|---|
| 616 | using CUPS (bug 467). |
|---|
| 617 | o Fix various SMB signing bugs. |
|---|
| 618 | o Fix ACL propagation on a DFS root (bug 263). |
|---|
| 619 | o Disable NTLM2 for RPC pipes. |
|---|
| 620 | o Allow the client to specify the NTLM2 flags got NTLMSSP |
|---|
| 621 | authentication. |
|---|
| 622 | o Change the name of the job passed off to cups from "Test Page" |
|---|
| 623 | to "smbprn.00000033 Test Page" so that we can get the smb |
|---|
| 624 | jobid back. This allow users to delete jobs with cups printing |
|---|
| 625 | backend (partial work on bug 770). |
|---|
| 626 | o Fix build of winbindd with static pdb modules. |
|---|
| 627 | o Retrieve the correct ACL group bits if the file has an ACL |
|---|
| 628 | (bug 802). |
|---|
| 629 | o Implement "net rpc group members": Get members of a domain group |
|---|
| 630 | in human-readable format. |
|---|
| 631 | o Add MacOSX (Darwin) specific charset module code. |
|---|
| 632 | o Use samr_dispinfo(level == 1) for enumerating domain users so we |
|---|
| 633 | can include the full name in gecos field (bug 587). |
|---|
| 634 | o Add support for winbind's NSS library on FeeeBSD 5.1 (bug 797). |
|---|
| 635 | o Implement 'net rpc group list [global|local|builtin]*' for a |
|---|
| 636 | select listing of the respective user databases. |
|---|
| 637 | o Don't automatically set NT status code flag unless client tells |
|---|
| 638 | us it can cope. |
|---|
| 639 | o Add 'net status [sessions|shares] [parseable]'. |
|---|
| 640 | o Don't mistake pre-existing UNIX jobs for smb jobs (remainder of |
|---|
| 641 | bug 770). |
|---|
| 642 | o Add 'Replicator' and 'RAS Servers' to list of builtin SIDs |
|---|
| 643 | (bug 608). |
|---|
| 644 | o Fix inverted logic in hosts allow/deny checks caused by |
|---|
| 645 | s/strcmp/strequal/ (bug 846). |
|---|
| 646 | o Implement correct version SamrRemoveSidForeignDomain() (bug 252). |
|---|
| 647 | o Fix typo in 'hash' mangling algorithm. |
|---|
| 648 | o Support munged dial for ldapsam (bug 800). |
|---|
| 649 | o Fix process_incoming_data() to return the number of bytes handled |
|---|
| 650 | this call whether we have a complete PDU or not; fixes bug |
|---|
| 651 | with multiple PDU request rpc's broken over SMBwriteX calls |
|---|
| 652 | each. |
|---|
| 653 | o Fix incorrect smb flags2 for connections to pre-NT servers |
|---|
| 654 | (causes smbclient to fail to OS2 for example) (bug 821). |
|---|
| 655 | o Update version string in smbldap-tools Makefile to 0.8.2. |
|---|
| 656 | o Correct a problem with "net rpc vampire" mis-parsing the |
|---|
| 657 | alias member info reply. |
|---|
| 658 | o Ensure the ${libdir} is created by the installclientlib script. |
|---|
| 659 | o Fix detection of Windows 2003 client architecture in the smb.conf |
|---|
| 660 | %a variable. |
|---|
| 661 | o Ensure that smbd calls the add user script for a missing UNIX |
|---|
| 662 | user on kerberos auth call (bug 445). |
|---|
| 663 | o Fix bugs in hosts allow/deny when using a mismatched |
|---|
| 664 | network/netmask pair. |
|---|

| 689 | ###################################################################### |
|---|
| 690 | |
|---|
| 691 | The original 3.0.0 release notes follow |
|---|
| 692 | ======================================= |
|---|
| 693 | WHATS NEW IN Samba 3.0.0 |
|---|
| 694 | September 24, 2003 |
|---|
| 695 | ======================================= |
|---|
| 696 | |
|---|
| 697 | |
|---|
| 698 | Major new features: |
|---|
| 699 | ------------------- |
|---|
| 700 | |
|---|
| 701 | 1) Active Directory support. Samba 3.0 is now able to |
|---|
| 702 | join a ADS realm as a member server and authenticate |
|---|
| 703 | users using LDAP/Kerberos. |
|---|
| 704 | |
|---|
| 705 | 2) Unicode support. Samba will now negotiate UNICODE on the wire |
|---|
| 706 | and internally there is now a much better infrastructure for |
|---|
| 707 | multi-byte and UNICODE character sets. |
|---|
| 708 | |
|---|
| 709 | 3) New authentication system. The internal authentication system |
|---|
| 710 | has been almost completely rewritten. Most of the changes are |
|---|
| 711 | internal, but the new auth system is also very configurable. |
|---|
| 712 | |
|---|
| 713 | 4) New default filename mangling system. |
|---|
| 714 | |
|---|
| 715 | 5) A new "net" command has been added. It is somewhat similar to |
|---|
| 716 | the "net" command in windows. Eventually we plan to replace |
|---|
| 717 | numerous other utilities (such as smbpasswd) with subcommands |
|---|
| 718 | in "net". |
|---|
| 719 | |
|---|
| 720 | 6) Samba now negotiates NT-style status32 codes on the wire. This |
|---|
| 721 | improves error handling a lot. |
|---|
| 722 | |
|---|
| 723 | 7) Better Windows 2000/XP/2003 printing support including publishing |
|---|

| 753 | ------------------------ |
|---|
| 754 | |
|---|
| 755 | Please refer to Samba documentation tree (included in the docs/ |
|---|
| 756 | subdirectory) for extensive explanations of installing, configuring |
|---|
| 757 | and maintaining Samba 3.0 servers and clients. It is advised to |
|---|
| 758 | begin with the Samba-HOWTO-Collection for overviews and specific |
|---|
| 759 | tasks (the current book is up to approximately 400 pages) and to |
|---|
| 760 | refer to the various man pages for information on individual options. |
|---|
| 761 | |
|---|
| 762 | We are very glad to be able to include the second edition of |
|---|
| 763 | "Using Samba" by Jay Ts, Robert Eckstein, and David Collier-Brown |
|---|
| 764 | (O'Reilly & Associates) in this release. The book is available |
|---|
| 765 | on-line at http://samba.org/samba/docs/ and is included with |
|---|

|---|
| 772 | Upgrading from a previous Samba 3.0 beta |
|---|
| 773 | ######################################## |
|---|
| 774 | |
|---|
| 775 | Beginning with Samba 3.0.0beta3, the RID allocation functions |
|---|
| 776 | have been moved into winbindd. Previously these were handled |
|---|
| 777 | by each passdb backend. This means that winbindd must be running |
|---|
| 778 | to automatically allocate RIDs for users and/or groups. Otherwise, |
|---|
| 779 | smbd will use the 2.2 algorithm for generating new RIDs. |
|---|
| 780 | |
|---|
| 781 | If you are using 'passdb backend = tdbsam' with a previous Samba |
|---|
| 782 | 3.0 beta release (or possibly alpha), it may be necessary to |
|---|
| 783 | move the RID_COUNTER entry from /usr/local/samba/private/passdb.tdb |
|---|
| 784 | to winbindd_idmap.tdb. To do this: |
|---|
| 785 | |
|---|
| 786 | 1) Ensure that winbindd_idmap.tdb exists (launch winbindd at least |
|---|
| 787 | once) |
|---|
| 788 | 2) build tdbtool by executing 'make tdbtool' in the source/tdb/ |
|---|
| 789 | directory |
|---|
| 790 | 3) run: (note that 'tdb>' is the tool's prompt for input) |
|---|
| 791 | |
|---|
| 792 | root# ./tdbtool /usr/local/samba/private/passdb.tdb |
|---|
| 793 | tdb> show RID_COUNTER |
|---|
| 794 | key 12 bytes |
|---|
| 795 | RID_COUNTER |
|---|
| 796 | data 4 bytes |
|---|
| 797 | [000] 0A 52 00 00 .R. |
|---|
| 798 | |
|---|
| 799 | tdb> move RID_COUNTER /usr/local/samba/var/locks/winbindd_idmap.tdb |
|---|
| 800 | .... |
|---|
| 801 | record moved |
|---|
| 802 | |
|---|
| 803 | If you are using 'passdb backend = ldapsam', it will be necessary to |
|---|
| 804 | store idmap entries in the LDAP directory as well (i.e. idmap backend |
|---|
| 805 | = ldap). Refer to the 'net idmap' command for more information on |
|---|
| 806 | migrating SID<->UNIX id mappings from one backend to another. |
|---|
| 807 | |
|---|
| 808 | If the RID_COUNTER record does not exist, then these instructions are |
|---|
| 809 | unneccessary and the new RID_COUNTER record will be correctly generated |
|---|
| 810 | if needed. |
|---|
| 811 | |

| 815 | Upgrading from Samba 2.2 |
|---|
| 816 | ######################## |
|---|
| 817 | |
|---|
| 818 | This section is provided to help administrators understand the details |
|---|
| 819 | involved with upgrading a Samba 2.2 server to Samba 3.0. |

| 821 | |
|---|
| 822 | Building |
|---|
| 823 | -------- |
|---|
| 824 | |
|---|
| 825 | Many of the options to the GNU autoconf script have been modified |
|---|
| 826 | in the 3.0 release. The most noticeable are: |
|---|
| 827 | |
|---|
| 828 | * removal of --with-tdbsam (is now included by default; see section |
|---|
| 829 | on passdb backends and authentication for more details) |
|---|
| 830 | |
|---|
| 831 | * --with-ldapsam is now on used to provided backward compatible |
|---|
| 832 | parameters for LDAP enabled Samba 2.2 servers. Refer to the passdb |
|---|
| 833 | backend and authentication section for more details |
|---|
| 834 | |
|---|
| 835 | * inclusion of non-standard passdb modules may be enabled using |
|---|
| 836 | --with-expsam. This includes an XML backend and a mysql backend. |
|---|
| 837 | |
|---|
| 838 | * removal of --with-msdfs (is now enabled by default) |
|---|
| 839 | |
|---|
| 840 | * removal of --with-ssl (no longer supported) |
|---|
| 841 | |
|---|
| 842 | * --with-utmp now defaults to 'yes' on supported systems |

| 986 | Databases |
|---|
| 987 | --------- |
|---|
| 988 | |
|---|
| 989 | This section contains brief descriptions of any new databases |
|---|
| 990 | introduced in Samba 3.0. Please remember to backup your existing |
|---|
| 991 | ${lock directory}/*tdb before upgrading to Samba 3.0. Samba will |
|---|
| 992 | upgrade databases as they are opened (if necessary), but downgrading |
|---|
| 993 | from 3.0 to 2.2 is an unsupported path. |
|---|
| 994 | |
|---|
| 995 | Name Description Backup? |
|---|
| 996 | ---- ----------- ------- |
|---|
| 997 | account_policy User policy settings yes |
|---|
| 998 | gencache Generic caching db no |
|---|
| 999 | group_mapping Mapping table from Windows yes |
|---|
| 1000 | groups/SID to unix groups |
|---|
| 1001 | winbindd_idmap ID map table from SIDS to UNIX yes |
|---|
| 1002 | uids/gids. |
|---|
| 1003 | namecache Name resolution cache entries no |
|---|
| 1004 | netsamlogon_cache Cache of NET_USER_INFO_3 structure no |
|---|
| 1005 | returned as part of a successful |
|---|
| 1006 | net_sam_logon request |
|---|
| 1007 | printing/*.tdb Cached output from 'lpq no |
|---|
| 1008 | command' created on a per print |
|---|
| 1009 | service basis |
|---|
| 1010 | registry Read-only samba registry skeleton no |
|---|
| 1011 | that provides support for exporting |
|---|
| 1012 | various db tables via the winreg RPCs |
|---|
| 1013 | |
|---|
| 1014 | |
|---|
| 1015 | Changes in Behavior |
|---|
| 1016 | ------------------- |
|---|
| 1017 | |
|---|
| 1018 | The following issues are known changes in behavior between Samba 2.2 and |
|---|
| 1019 | Samba 3.0 that may affect certain installations of Samba. |
|---|
| 1020 | |
|---|
| 1021 | 1) When operating as a member of a Windows domain, Samba 2.2 would |
|---|
| 1022 | map any users authenticated by the remote DC to the 'guest account' |
|---|
| 1023 | if a uid could not be obtained via the getpwnam() call. Samba 3.0 |
|---|
| 1024 | rejects the connection as NT_STATUS_LOGON_FAILURE. There is no |
|---|
| 1025 | current work around to re-establish the 2.2 behavior. |
|---|
| 1026 | |
|---|
| 1027 | 2) When adding machines to a Samba 2.2 controlled domain, the |
|---|
| 1028 | 'add user script' was used to create the UNIX identity of the |
|---|
| 1029 | machine trust account. Samba 3.0 introduces a new 'add machine |
|---|
| 1030 | script' that must be specified for this purpose. Samba 3.0 will |
|---|
| 1031 | not fall back to using the 'add user script' in the absence of |
|---|
| 1032 | an 'add machine script' |
|---|
| 1033 | |

|---|
| 1036 | Passdb Backends and Authentication |
|---|
| 1037 | ################################## |
|---|
| 1038 | |
|---|
| 1039 | There have been a few new changes that Samba administrators should be |
|---|
| 1040 | aware of when moving to Samba 3.0. |
|---|
| 1041 | |
|---|
| 1042 | 1) encrypted passwords have been enabled by default in order to |
|---|
| 1043 | inter-operate better with out-of-the-box Windows client |
|---|
| 1044 | installations. This does mean that either (a) a samba account |
|---|
| 1045 | must be created for each user, or (b) 'encrypt passwords = no' |
|---|
| 1046 | must be explicitly defined in smb.conf. |
|---|
| 1047 | |
|---|
| 1048 | 2) Inclusion of new 'security = ads' option for integration |
|---|
| 1049 | with an Active Directory domain using the native Windows |
|---|
| 1050 | Kerberos 5 and LDAP protocols. |
|---|
| 1051 | |
|---|
| 1052 | MIT kerberos 1.3.1 supports the ARCFOUR-HMAC-MD5 encryption |
|---|
| 1053 | type which is neccessary for servers on which the |
|---|
| 1054 | administrator password has not been changed, or kerberos-enabled |
|---|
| 1055 | SMB connections to servers that require Kerberos SMB signing. |
|---|
| 1056 | Besides this one difference, either MIT or Heimdal Kerberos |
|---|
| 1057 | distributions are usable by Samba 3.0. |
|---|
| 1058 | |
|---|
| 1059 | |
|---|
| 1060 | Samba 3.0 also includes the possibility of setting up chains |
|---|
| 1061 | of authentication methods (auth methods) and account storage |
|---|
| 1062 | backends (passdb backend). Please refer to the smb.conf(5) |
|---|
| 1063 | man page for details. While both parameters assume sane default |
|---|
| 1064 | values, it is likely that you will need to understand what the |
|---|
| 1065 | values actually mean in order to ensure Samba operates correctly. |
|---|
| 1066 | |
|---|
| 1067 | The recommended passdb backends at this time are |
|---|
| 1068 | |
|---|
| 1069 | * smbpasswd - 2.2 compatible flat file format |
|---|
| 1070 | * tdbsam - attribute rich database intended as an smbpasswd |
|---|
| 1071 | replacement for stand alone servers |
|---|
| 1072 | * ldapsam - attribute rich account storage and retrieval |
|---|
| 1073 | backend utilizing an LDAP directory. |
|---|
| 1074 | * ldapsam_compat - a 2.2 backward compatible LDAP account |
|---|
| 1075 | backend |
|---|
| 1076 | |
|---|
| 1077 | Certain functions of the smbpasswd(8) tool have been split between the |
|---|
| 1078 | new smbpasswd(8) utility, the net(8) tool, and the new pdbedit(8) |
|---|
| 1079 | utility. See the respective man pages for details. |

|---|
| 1083 | LDAP |
|---|
| 1084 | #### |
|---|
| 1085 | |
|---|
| 1086 | This section outlines the new features affecting Samba / LDAP |
|---|
| 1087 | integration. |
|---|
| 1088 | |
|---|
| 1089 | New Schema |
|---|
| 1090 | ---------- |
|---|
| 1091 | |
|---|
| 1092 | A new object class (sambaSamAccount) has been introduced to replace |
|---|
| 1093 | the old sambaAccount. This change aids us in the renaming of |
|---|
| 1094 | attributes to prevent clashes with attributes from other vendors. |
|---|
| 1095 | There is a conversion script (examples/LDAP/convertSambaAccount) to |
|---|
| 1096 | modify and LDIF file to the new schema. |
|---|
| 1097 | |
|---|
| 1098 | Example: |
|---|
| 1099 | |
|---|
| 1100 | $ ldapsearch .... -b "ou=people,dc=..." > sambaAcct.ldif |
|---|
| 1101 | $ convertSambaAccount --sid=<Domain SID> \ |
|---|
| 1102 | --input=sambaAcct.ldif --output=sambaSamAcct.ldif \ |
|---|
| 1103 | --changetype=[modify|add] |
|---|
| 1104 | |
|---|
| 1105 | The <DOM SID> can be obtained by running 'net getlocalsid |
|---|
| 1106 | <DOMAINNAME>' on the Samba PDC as root. The changetype determines |
|---|
| 1107 | the format of the generated LDIF output--either create new entries |
|---|
| 1108 | or modify existing entries. |
|---|
| 1109 | |
|---|
| 1110 | The old sambaAccount schema may still be used by specifying the |
|---|
| 1111 | "ldapsam_compat" passdb backend. However, the sambaAccount and |
|---|
| 1112 | associated attributes have been moved to the historical section of |
|---|
| 1113 | the schema file and must be uncommented before use if needed. |
|---|
| 1114 | The 2.2 object class declaration for a sambaAccount has not changed |
|---|
| 1115 | in the 3.0 samba.schema file. |
|---|
| 1116 | |
|---|
| 1117 | Other new object classes and their uses include: |
|---|
| 1118 | |
|---|
| 1119 | * sambaDomain - domain information used to allocate rids |
|---|
| 1120 | for users and groups as necessary. The attributes are added |
|---|
| 1121 | in 'ldap suffix' directory entry automatically if |
|---|
| 1122 | an idmap uid/gid range has been set and the 'ldapsam' |
|---|
| 1123 | passdb backend has been selected. |
|---|
| 1124 | |
|---|
| 1125 | * sambaGroupMapping - an object representing the |
|---|
| 1126 | relationship between a posixGroup and a Windows |
|---|
| 1127 | group/SID. These entries are stored in the 'ldap |
|---|
| 1128 | group suffix' and managed by the 'net groupmap' command. |
|---|
| 1129 | |
|---|
| 1130 | * sambaUnixIdPool - created in the 'ldap idmap suffix' entry |
|---|
| 1131 | automatically and contains the next available 'idmap uid' and |
|---|
| 1132 | 'idmap gid' |
|---|
| 1133 | |
|---|
| 1134 | * sambaIdmapEntry - object storing a mapping between a |
|---|
| 1135 | SID and a UNIX uid/gid. These objects are created by the |
|---|
| 1136 | idmap_ldap module as needed. |
|---|
| 1137 | |
|---|
| 1138 | * sambaSidEntry - object representing a SID alone, as a Structural |
|---|
| 1139 | class on which to build the sambaIdmapEntry. |
|---|
| 1140 | |
|---|
| 1141 | |
|---|
| 1142 | New Suffix for Searching |
|---|
| 1143 | ------------------------ |
|---|
| 1144 | |
|---|
| 1145 | The following new smb.conf parameters have been added to aid in directing |
|---|
| 1146 | certain LDAP queries when 'passdb backend = ldapsam://...' has been |
|---|
| 1147 | specified. |
|---|
| 1148 | |
|---|
| 1149 | * ldap suffix - used to search for user and computer accounts |
|---|
| 1150 | * ldap user suffix - used to store user accounts |
|---|
| 1151 | * ldap machine suffix - used to store machine trust accounts |
|---|
| 1152 | * ldap group suffix - location of posixGroup/sambaGroupMapping entries |
|---|
| 1153 | * ldap idmap suffix - location of sambaIdmapEntry objects |
|---|
| 1154 | |
|---|
| 1155 | If an 'ldap suffix' is defined, it will be appended to all of the |
|---|
| 1156 | remaining sub-suffix parameters. In this case, the order of the suffix |
|---|
| 1157 | listings in smb.conf is important. Always place the 'ldap suffix' first |
|---|
| 1158 | in the list. |
|---|
| 1159 | |
|---|
| 1160 | Due to a limitation in Samba's smb.conf parsing, you should not surround |
|---|
| 1161 | the DN's with quotation marks. |
|---|
| 1162 | |
|---|
| 1163 | |
|---|
| 1164 | IdMap LDAP support |
|---|
| 1165 | ------------------ |
|---|
| 1166 | |
|---|
| 1167 | Samba 3.0 supports an ldap backend for the idmap subsystem. The |
|---|
| 1168 | following options would inform Samba that the idmap table should be |
|---|
| 1169 | stored on the directory server onterose in the "ou=idmap,dc=plainjoe, |
|---|
| 1170 | dc=org" partition. |
|---|
| 1171 | |
|---|
| 1172 | [global] |
|---|
| 1173 | ... |
|---|
| 1174 | idmap backend = ldap:ldap://onterose/ |
|---|
| 1175 | ldap idmap suffix = ou=idmap,dc=plainjoe,dc=org |
|---|
| 1176 | idmap uid = 40000-50000 |
|---|
| 1177 | idmap gid = 40000-50000 |
|---|
| 1178 | |
|---|
| 1179 | This configuration allows winbind installations on multiple servers to |
|---|
| 1180 | share a uid/gid number space, thus avoiding the interoperability problems |
|---|
| 1181 | with NFS that were present in Samba 2.2. |

| 1186 | Trust Relationships and a Samba Domain |
|---|
| 1187 | ###################################### |
|---|
| 1188 | |
|---|
| 1189 | Samba 3.0.0beta2 is able to utilize winbindd as the means of |
|---|
| 1190 | allocating uids and gids to trusted users and groups. More |
|---|
| 1191 | information regarding Samba's support for establishing trust |
|---|
| 1192 | relationships can be found in the Samba-HOWTO-Collection included |
|---|
| 1193 | in the docs/ directory of this release. |
|---|
| 1194 | |
|---|
| 1195 | First create your Samba PDC and ensure that everything is |
|---|
| 1196 | working correctly before moving on the trusts. |
|---|
| 1197 | |
|---|
| 1198 | To establish Samba as the trusting domain (named SAMBA) from a Windows NT |
|---|
| 1199 | 4.0 domain named WINDOWS: |
|---|
| 1200 | |
|---|
| 1201 | 1) create the trust account for SAMBA in "User Manager for Domains" |
|---|
| 1202 | 2) connect the trust from the Samba domain using |
|---|
| 1203 | 'net rpc trustdom establish GLASS' |
|---|
| 1204 | |
|---|
| 1205 | To create a trustlationship with SAMBA as the trusted domain: |
|---|
| 1206 | |
|---|
| 1207 | 1) create the initial trust account for GLASS using |
|---|
| 1208 | 'smbpasswd -a -i GLASS'. You may need to create a UNIX |
|---|
| 1209 | account for GLASS$ prior to this step (depending on your |
|---|
| 1210 | local configuration). |
|---|
| 1211 | 2) connect the trust from a WINDOWS DC using "User Manager |
|---|
| 1212 | for Domains" |
|---|
| 1213 | |
|---|
| 1214 | Now join winbindd on the Samba PDC to the SAMBA domain using |
|---|
| 1215 | the normal steps for adding a Samba server to an NT4 domain: |
|---|
| 1216 | (note that smbd & nmbd must be running at this point) |
|---|
| 1217 | |
|---|
| 1218 | root# net rpc join -U root |
|---|
| 1219 | Password: <enter root password from smbpasswd file here> |
|---|
| 1220 | |
|---|
| 1221 | Start winbindd and test the join with 'wbinfo -t'. |
|---|
| 1222 | |
|---|
| 1223 | Now test the trust relationship by connecting to the SAMBA DC |
|---|
| 1224 | (e.g. POGO) as a user from the WINDOWS domain: |
|---|
| 1225 | |
|---|
| 1226 | $ smbclient //pogo/netlogon -U Administrator -W WINDOWS |
|---|
| 1227 | Password: |
|---|
| 1228 | |
|---|
| 1229 | Now connect to the WINDOWS DC (e.g. CRYSTAL) as a Samba user: |
|---|
| 1230 | |
|---|
| 1231 | $ smbclient //crystal/netlogon -U root -W WINDOWS |
|---|
| 1232 | Password: |
|---|

| 1235 | Changes in Winbind |
|---|
| 1236 | ################## |
|---|
| 1237 | |
|---|
| 1238 | Beginning with Samba3.0.0beta3, winbindd has been given new account |
|---|
| 1239 | manage functionality equivalent to the 'add user script' family of |
|---|
| 1240 | smb.conf parameters. The idmap design has also been changed to |
|---|
| 1241 | centralize control of foreign SID lookups and matching to UNIX |
|---|
| 1242 | uids and gids. |
|---|
| 1243 | |
|---|
| 1244 | |
|---|
| 1245 | Brief Description of Changes |
|---|
| 1246 | ---------------------------- |
|---|
| 1247 | |
|---|
| 1248 | 1) The sid_to_uid() family of functions (smbd/uid.c) have been |
|---|
| 1249 | reverted to the 2.2.x design. This means that when resolving a |
|---|
| 1250 | SID to a UID or similar mapping: |
|---|
| 1251 | |
|---|
| 1252 | a) First consult winbindd |
|---|
| 1253 | b) perform a local lookup only if winbindd fails to |
|---|
| 1254 | return a successful answer |
|---|
| 1255 | |
|---|
| 1256 | There are some variations to this, but these two rules generally |
|---|
| 1257 | apply. |
|---|
| 1258 | |
|---|
| 1259 | 2) All idmap lookups have been moved into winbindd. This means that |
|---|
| 1260 | a server must run winbindd (and support NSS) in order to achieve |
|---|
| 1261 | any mappings of SID to dynamically allocated UNIX ids. This was |
|---|
| 1262 | a conscious design choice. |
|---|
| 1263 | |
|---|
| 1264 | 3) New functions have been added to winbindd to emulate the 'add user |
|---|
| 1265 | script' family of smbd functions without requiring that external |
|---|
| 1266 | scripts be defined. This functionality is controlled by the 'winbind |
|---|
| 1267 | enable local accounts' smb.conf parameter (enabled by default). |
|---|
| 1268 | |
|---|
| 1269 | However, this account management functionality is only supported |
|---|
| 1270 | in a local tdb (winbindd_idmap.tdb). If these new UNIX accounts |
|---|
| 1271 | must be shared among multiple Samba servers (such as a PDC and BDCs), |
|---|
| 1272 | it will be necessary to define your own 'add user script', et. al. |
|---|
| 1273 | programs that place the accounts/groups in some form of directory |
|---|
| 1274 | such as NIS or LDAP. This requirement was deemed beyond the scope |
|---|
| 1275 | of winbind's account management functions. Solutions for |
|---|
| 1276 | distributing UNIX system information have been deployed and tested |
|---|
| 1277 | for many years. We saw no need to reinvent the wheel. |
|---|
| 1278 | |
|---|
| 1279 | 4) A member of a Samba controlled domain running winbindd is now able |
|---|
| 1280 | to map domain users directly onto existing UNIX accounts while still |
|---|
| 1281 | automatically creating accounts for trusted users and groups. This |
|---|
| 1282 | behavior is controlled by the 'winbind trusted domains only' smb.conf |
|---|
| 1283 | parameter (disabled by default to provide 2.2.x winbind behavior). |
|---|
| 1284 | |
|---|
| 1285 | 5) Group mapping support is wrapped in the local_XX_to_XX() functions |
|---|
| 1286 | in smbd/uid.c. The reason that group mappings are not included |
|---|
| 1287 | in winbindd is because the purpose of Samba's group map is to |
|---|
| 1288 | match any Windows SID with an existing UNIX group. These UNIX |
|---|
| 1289 | groups can be created by winbindd (see next section), but the |
|---|
| 1290 | SID<->gid mapping is retreived by smbd, not winbindd. |
|---|
| 1291 | |
|---|
| 1292 | |
|---|
| 1293 | Examples |
|---|
| 1294 | -------- |
|---|
| 1295 | |
|---|
| 1296 | * security = server running winbindd to allocate accounts on demand |
|---|
| 1297 | |
|---|
| 1298 | * Samba PDC running winbindd to handle the automatic creation of UNIX |
|---|
| 1299 | identities for machine trust accounts |
|---|
| 1300 | |
|---|
| 1301 | * Automtically creating UNIX user and groups when migrating a Windows NT |
|---|
| 1302 | 4.0 PDC to a Samba PDC. Winbindd must be running when executing |
|---|
| 1303 | 'net rpc vampire' for this to work. |
