- July 16 2003
+ WHATS NEW IN Samba 3.0.0 RC3
+ September 8, 2003
==============================
-This is the third beta release of Samba 3.0.0. This is a
-non-production release intended for testing purposes. Use
-at your own risk.
+This is the third release candidate snapshot of Samba 3.0.0. A release
+candidate implies that the code is very close to a final release, remember
+that this is still a non-production release intended for testing purposes.
+Use at your own risk.
-The purpose of this beta release is to get wider testing of the major
-new pieces of code in the current Samba 3.0 development tree. We have
-officially ceased development on the 2.2.x release of Samba and are
-concentrating on Samba 3.0. To reduce the time before the final
-Samba 3.0 release we need as many people as possible to start testing
-these beta releases, and to provide high quality feedback on what
-needs fixing.
-
-Samba 3.0 is feature complete. However there is still some final
-work to be done on certain pieces of functionality. Please refer to
-the section on "Known Issues" for more details.

Major new features:
-------------------
1) Active Directory support. Samba 3.0 is now able to
- to join a ADS realm as a member server and authenticate
+ 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
been almost completely rewritten. Most of the changes are internal,
but the new auth system is also very configurable.
-4) New filename mangling system. The filename mangling system has been
- completely rewritten. An internal database now stores mangling maps
- persistently. This needs lots of testing.
+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
7) Better Windows 2000/XP/2003 printing support including publishing
printer attributes in active directory.
-8) New loadable RPC modules.
+8) New loadable module support for passdb backends and
+ character sets.
-9) New dual-daemon winbindd support for better performance.
+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.
13) Major updates to the Samba documentation tree.
+14) Full support for client and server SMB signing to ensure
+ compatibility with default Windows 2003 security settings.
+
Plus lots of other improvements!

+Please refer to Samba documentation tree (included in the docs/

refer to the various man pages for information on individual options.

+####################
Please refer to the CVS log for the SAMBA_3_0 branch for complete
-details
+details:
+
+1) Remove Perl module dependencies in generated RedHat 8/9 RPMS.
+2) Update mount helper to take synonyms for file_mode and
+ dir_mode (fmask and dmask).
+3) Fix portability bug with log2pcaphex.
+4) Use different algorithm to generate codepages source code which
+ allows to take gaps into account thus making unnecessary
+ extended [index] = value, syntax in to_ucs2 array (bug 380).
+5) Fix comment strings to 43 bytes as per spec.
+6) Fix pam_winbind compile bug on FreeBSD (bug 261).
+7) Support for in-memory keytabs, which are needed to make heimdal
+ work properly. MIT does not support them, so this check will be
+ used to decide whether to use them. (partial fix for bug 372).
+8) Disable RC4-HMAC on broken heimdal setups. (remainder of bug
+ 372).
+9) Correct bug in smbclient that resulted in errors when untarring
+ long filenames (bug 308).
+10) Improve autoconf checks for PAM header files and libs.
+11) Added fast path to convert_string() when dealing with
+ ASCII->ASCII, UCS2-LE->ASCII, and ASCII->UCS2-LE with
+ values <= 0x7F.
+12) Quiet debug messages when we don't find a module and it is not
+ a critical error (bug 375).
+13) Fix UNIX passwd sync properly.

+15) Ensure that winbindd functions with 'disable netbios = yes'
+16) Store the real short domain name in secrets.tdb as soon as we
+ know it. Also display an error message when joining an AD
+ domain and the 'workgroup' parameter has not been specified.
+17) Return 0 DFS links instead of -1 when dfs support is not enabled.
+18) Update LDAP schema for Netscape DS 4.x and Novell eDirectory 8.7
+19) Ensure that name types can be specified using name#type notation
+ in the 'net' command (bug 73).
+20) Add retry looks to ADS sequence number and domain SID lookups
+ (bug 364).
+21) use a variant of alloc_sub_basic() for string lists such as

+ in response to an LDAP search (bug 282).
+23) Update findsmb to use the new syntax for smbclient and nmblookup.
+24) Fix bug that prevented variables from being used in explicitly
+ defined path in [homes].
+25) Only set SIDs when they're returned by the MySQL query

+27) Revert default for 'client ntlmv2 auth' to off (bug 359).
+28) Fix crash in winbindd when the trust account password gets
+ changed underneath us via 'net rpc changetrustpw' (bug 382).
+29) Use djb-algorithm string hash - faster than the tdb one we
+ used to use. Does not change on disk format or hashing location.
+30) Implements some kind of improved AFS support for Samba on
+ Linux with OpenAFS 1.2.10. './configure --with-fake-kaserver'
+ assumes that you have OpenAFS on your machine.
+31) When enumerating dfs shares loop from 0 to lp_numservices() instead
+ of relying on lp_servicename(n) to return an empty string for
+ invalid service numbers (bug 403).
+32) Fix crash bug in 'net rpc samdump' (bug 334).
+33) Fix crash bug in WINS NSS module (bug 299).
+34) Fix a few minor compile errors on HP-UX.

######################################################################
+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.
