Release Announcements

This is the first release candidate of Samba 3.3.0.  This is *not*
intended for production environments and is designed for testing
purposes only.  Please report any defects via the Samba bug reporting
system at https://bugzilla.samba.org/.

Major enhancements in Samba 3.3.0 include:

 o Splitting of library directory into library directory and separate
   modules directory.

 File Serving:
 o Extended Cluster support.

 o Simplified idmap configuration.
 o New idmap backends "adex" and "hash".
 o Added new parameter "winbind reconnect delay".
 o Added support for user and group aliasing.

 Administrative tools:
 o The destination "all" of smbcontrol does now affect all running
   daemons including nmbd and winbindd.
 o New 'net rpc vampire keytab' and 'net rpc vampire ldif' commands.
 o The 'net' utility can now use kerberos for joining and authentication.
 o The 'wbinfo' utility can now add, modify and remove identity mapping entries.

 o NetApi library implements various new calls for User- and Group
   Account Management.

Configure changes

The configure option "--with-libdir" has been removed. The library
directory can still be specified by using the existing "--libdir" option.
A new option "--with-modulesdir" has been added to allow the specification
of a separate directory for the shared modules.

Winbind idmap backend changes

The idmap configuration has changed with version 3.3 to something that
allows a smoother upgrade path from pre-3.0.25 configurations that use
"idmap backend". The reason for this change is that to many, also to Samba
developers, the 3.0.25 style configuration with "idmap config" turned out
to be very complex. Version 3.3 no longer deprecates the "idmap backend"
parameter, instead with "idmap backend" the default idmap backend is

Accordingly, the "idmap config <domain> : default = yes" setting is no
longer being looked at.

The alloc backend defaults to the default backend, which should be able to
allocate IDs. In the default distribution the tdb and ldap backends can
allocate, the ad and rid backends can not. The idmap alloc range is now
being set with the "old" parameters "idmap uid" and "idmap gid".

The "idmap domains" parameter has been removed.

winbind reconnect delay

This is a new parameter which specifies the number of seconds the Winbind
daemon will wait between attempts to contact a Domain controller for a domain
that is determined to be down or not contactable.

Winbind's Name Aliasing

Name aliasing in Winbind is a feature that allows an administrator to
map a fully qualified user or group name from a Windows domain to a
convenient short name for Unix access.  This is similar to the username
map functionality supported by smbd but is primary intended for
clients and servers making use of Winbind's PAM and NSS libraries.

For example, the user "DOMAIN\fred" has been mapped to the Unix name

   $ getent passwd "DOMAIN\fred"
   freddie:x:1000:1001:Fred Jones:/home/freddie:/bin/bash

   $ getent passwd freddie
   freddie:x:1000:1001:Fred Jones:/home/freddie:/bin/bash

The name aliasing support is provided by individual nss_info plugins.
For example, the new "adex" plugin reads the uid attribute from Active
Directory to make a short login name to the fully qualified name.
While the new "hash" module utilizes a local file to map "short_name
= QUALIFIED\name".  Both user and group name mapping is supported.
Please refer to the "winbind nss info" option in smb.conf(5) and
to individual plugin man pages for further details.


The idmap_hash plugin provides similar support as the idmap_rid
module.  However, uids and gids are generated from the full domain
SID using a hashing algorithm that maps the lower 19 bits from the user
or group RID to bits 0 - 19 in the Unix id and hashes 96 bits from
the domain SID to bits 20 - 30 in the Unix id.  The result is a 31 bit
uid or gid that is consistent across machines and provides support for
trusted domains.

Please refer to the idmap_hash(8) man page for more details.


The adex idmap/nss_info plugin is an adaptation of the Likewise
Enterprise plugin with support for OU based cells removed
(since the Windows pieces to manage the cells are not available).

This plugin supports

      * The RFC2307 schema for users and groups.
      * Connections to trusted domains
      * Global catalog searches
      * Cross forest trusts
      * User and group aliases

Prerequisite: Add the following attributes to the Partial Attribute
Set in global catalog:

      * uidNumber
      * uid
      * gidNumber

A basic config using the current trunk code would look like:

	idmap backend = adex
	idmap uid = 10000 - 29999
	idmap gid = 10000 - 29999
	winbind nss info = adex

	winbind normalize names = yes
	winbind refresh tickets = yes
	template homedir = /home/%D/%U
	template shell = /bin/bash

Please refer to the idmap_adex(8) man page for more details.
