WHATS NEW IN Samba 3.0 alpha24
|
||||
14th May 2003
|

==============================
|

|
||||
This is a pre-release of Samba 3.0. This is NOT a stable release.

Use at your own risk.
|

|

The purpose of this alpha release is to get wider testing of the major

new pieces of code in the current Samba 3.0 development tree. We have

|

Changes in alpha23:
|
||||
-------------------
|
||||
|
||||
LDAP Group Mapping
|
||||
------------------
|
||||
|
||||
pdbedit -i -e sets all SAM_ACCOUNT elements to CHANGED to
|
||||
satisfy the new pdb_ldap.c handling. pdbedit -g transfers group
|
||||
mappings. I made this separate from the user database, as current
|
||||
installations have to live with a split backend. So, if you are
|
||||
running 3_0 alphas with LDAP as a backend and upgrade to 3.0alpha23,
|
||||
you must call
|
||||
|
||||
root# pdbedit -i tdbsam -e ldapsam -g
|
||||
|
||||
to transfer your group mapping database to LDAP.
|
||||
|
||||
All groups must be represented as posixGroup objects in
|
||||
the directory and you must adapt your LDAP schema to support the
|
||||
sambaGroupMapping before running this command. Refer to
|
||||
examples/LDAP/samba.schema for details on the objectclass.
|
||||
|
||||
|
||||
LDAP Schema Changes
|
||||
-------------------
|
||||
A new objectclass (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=..." > old.ldif
|
||||
$ convertSambaAccount <DOM SID> old.ldif new.ldif
|
||||
|
||||
The <DOM SID> can be obtained by running 'net getlocalsid <DOMAINNAME>'
|
||||
on the Samba PDC as root.
|
||||
|
||||
The sambaDomain and sambaGroupMapping objects have also been modified
|
||||
to use the new attribute naming conventions as well. There are no
|
||||
conversion scripts for this data since the old schema was never published
|
||||
in a stable release.
|
||||
|
||||
The old sambaAccount schema may still be used by specifying the
|
||||
"ldapsam_compat" passdb backend.
|
||||
|
||||
Parameters
|
||||
----------
|
||||
|
||||
Modified Parameters (see smb.conf(5) for details):
|
||||
|
||||
* passdb backend
|
||||
|
||||
Added Parameters
|
||||
|
||||
* ldap del only sam attr
|
||||
* ldap delete dn
|
||||
Removed Parameters
|
||||
|
||||
* total print jobs
|
||||
|
||||
Known Issues
|
||||
------------
|
||||
|
||||
The following are known issues with this release and will be corrected
|
||||
in future versions:
|
||||
|
||||
1) Automatically generating accounts for users and groups from
|
||||
trusted domains when Samba is acting as a PDC
|
||||
2) Maintaining idmap ID's in a LDAP directory in order to implement
|
||||
a distributed winbind solution
|
||||
|
||||
ChangeLog
|
||||
---------
|
||||
|
||||
See cvs log for SAMBA_3_0 for complete details. There are many
|
||||
smaller numerous changes that would clutter the release notes.
|
||||
|
||||
0) Include security fix from Samba 2.2.8
|
||||
1) Fix interop bug in tconX on port 445 with Windows 2000
|
||||
2) Interpret missing SMB_ACL_USER_OBJ, SMB_ACL_GROUP_OBJ, or
|
||||
SMB_ACL_OTHER as "preserve current value" instead of attempting
|
||||
to build one ourself.
|
||||
3) Rearrange set_nt_acl() such that chown is only done before
|
||||
setting ACLs if there is either no change of owning user, or
|
||||
change of owning user is towards the current user. Otherwise
|
||||
chown is done after setting ACLs.
|
||||
4) Continuing work on NTLMSSP-based SMB signing
|
||||
5) When opening an existing TDB, don't require the hash_size
|
||||
specified to the open call to be the same as that of the
|
||||
existing tdb. The specified hash_size is only used if the
|
||||
tdb needs to be (re)created.
|
||||
6) Add support for "WinXP" and "Win2K3" client architectures.
|
||||
7) Fixed the unmarshalling of the queryaliasmem SAMR call
|
||||
8) Windows 2000 can take much longer than the specified time to
|
||||
respond to a lock - so to make the torture tests valid I give
|
||||
it a grace time of 10 seconds instead of 2
|
||||
9) Continued work on string handling paranoia
|
||||
10) Merge new statcache.c from HEAD
|
||||
11) Add new 'net ads dn' option
|
||||
12) Sync up SessionSetup code to HEAD, including Luke Howard's
|
||||
session key and auth verifier patches
|
||||
13) Work on cleaning up winbindd's mutex locking
|
||||
14) Add support for LDAP based Windows group mapping
|
||||
15) Improve LDAP update routines
|
||||
16) Fix memory leaks found by Valgrind
|
||||
17) Add a 'privileged' mode to Winbindd
|
||||
18) Work around platforms that have broken getgrnam() implementations
|
||||
19) Merge real time signal fixes for kernel oplock code from HEAD
|
||||
20) Fix CIDR hosts allow/deny notation
|
||||
21) Fixup tcon&X server responses and error codes
|
||||
22) Set domain for users in passdb created by "net rpc vampire"
|
||||
23) More scalable printing updates
|
||||

||||
===============================
|
||||
|
||||
Changes in older alpha releases follow:
|
||||
|
||||
---------------------------------------------------------------------
|
||||
|
||||
Changes in alpha22:
|
||||
-------------------
|
||||
|
||||
Added Parameters
|
||||
|
||||
* client NTLMv2 auth
|
||||
* client lanman auth
|
||||
* client signing
|
||||
* client use spnego
|
||||
* max reported print jobs
|
||||
* msdfs proxy
|
||||
|
||||
1) remove the global_myname string and replace with wrapper function
|
||||
global_myname()
|
||||
2) create vfs/ and pdb/ subdirectories for library installs
|
||||
3) Fixup of ordered cleanup of get_dc_list()
|
||||
4) Added more autoconf tests for Stratus VOS
|
||||
5) Fixed nasty bug where file writes with start offsets in the
|
||||
range 0x80000000 -> 0xFFFFFFFF would fail as they were being cast
|
||||
from IVAL (uint32) to SMB_OFF_T (off_t or off64_t, both *signed*
|
||||
types). The sign extension would cause the offset to be treated
|
||||
as negative.
|
||||
6) Add support to automatically retrieve the dns host name and domain
|
||||
name of an AD server
|
||||
7) Add support for PRINTER_INFO_7 and publishing printer attributes
|
||||
in active directory

|
||||
DOMAIN<0x1b>

|
||||
no dependent files
|
||||

|
||||
20) Protect nmbd against malformed reply packets
|
||||
21) Removal of unpopular winbind client environment variable
|
||||
22) Add msdfs proxy functionality; a CIFS share can directly be a
|
||||
stand-in for another share, and when clients connect to the first
|
||||
share, they will be redirected to the proxied share
|
||||
23) Make Samba compile cleanly with -Wwrite-strings
|

|
||||
smb -> smb lock release). Adds new PENDING_LOCK type to lockdb (does
|
||||
not interfere with existing locks)
|
||||
50) Limit the unix domain sockets used by winbindd (also solves FD_SETSIZE
|
||||
problem in winbindd to boot !). Adds a "last_access" field to winbindd
|
||||
connections, and will close the oldest idle connection once the number
|
||||
of open connections goes over WINBINDD_MAX_SIMULTANEOUS_CLIENTS (defined
|
||||
