2 Release Notes for Samba 3.3.0rc1
4 ================================
6 This is the first release candidate of Samba 3.3.0. This is *not*
7 intended for production environments and is designed for testing
8 purposes only. Please report any defects via the Samba bug reporting
9 system at https://bugzilla.samba.org/.
11 Major enhancements in Samba 3.3.0 include:
13 Configuration/installation:
14 o Splitting of library directory into library directory and separate
18 o Extended Cluster support.
21 o Simplified idmap configuration.
22 o New idmap backends "adex" and "hash".
23 o Added new parameter "winbind reconnect delay".
24 o Added support for user and group aliasing.
27 o The destination "all" of smbcontrol does now affect all running
28 daemons including nmbd and winbindd.
29 o New 'net rpc vampire keytab' and 'net rpc vampire ldif' commands.
30 o The 'net' utility can now use kerberos for joining and authentication.
33 o NetApi library implements various new calls for User- and Group
40 The configure option "--with-libdir" has been removed. The library
41 directory can still be specified by using the existing "--libdir" option.
42 A new option "--with-modulesdir" has been added to allow the specification
43 of a separate directory for the shared modules.
46 Winbind idmap backend changes
47 =============================
49 The idmap configuration has changed with version 3.3 to something that
50 allows a smoother upgrade path from pre-3.0.25 configurations that use
51 "idmap backend". The reason for this change is that to many, also to Samba
52 developers, the 3.0.25 style configuration with "idmap config" turned out
53 to be very complex. Version 3.3 no longer deprecates the "idmap backend"
54 parameter, instead with "idmap backend" the default idmap backend is
57 Accordingly, the "idmap config <domain> : default = yes" setting is no
58 longer being looked at.
60 The alloc backend defaults to the default backend, which should be able to
61 allocate IDs. In the default distribution the tdb and ldap backends can
62 allocate, the ad and rid backends can not. The idmap alloc range is now
63 being set with the "old" parameters "idmap uid" and "idmap gid".
65 The "idmap domains" parameter has been removed.
68 winbind reconnect delay
69 =======================
71 This is a new parameter which specifies the number of seconds the Winbind
72 daemon will wait between attempts to contact a Domain controller for a domain
73 that is determined to be down or not contactable.
76 Winbind's Name Aliasing
77 =======================
79 Name aliasing in Winbind is a feature that allows an administrator to
80 map a fully qualified user or group name from a Windows domain to a
81 convenient short name for Unix access. This is similar to the username
82 map functionality supported by smbd but is primary intended for
83 clients and servers making use of Winbind's PAM and NSS libraries.
85 For example, the user "DOMAIN\fred" has been mapped to the Unix name
88 $ getent passwd "DOMAIN\fred"
89 freddie:x:1000:1001:Fred Jones:/home/freddie:/bin/bash
91 $ getent passwd freddie
92 freddie:x:1000:1001:Fred Jones:/home/freddie:/bin/bash
94 The name aliasing support is provided by individual nss_info plugins.
95 For example, the new "adex" plugin reads the uid attribute from Active
96 Directory to make a short login name to the fully qualified name.
97 While the new "hash" module utilizes a local file to map "short_name
98 = QUALIFIED\name". Both user and group name mapping is supported.
99 Please refer to the "winbind nss info" option in smb.conf(5) and
100 to individual plugin man pages for further details.
106 The idmap_hash plugin provides similar support as the idmap_rid
107 module. However, uids and gids are generated from the full domain
108 SID using a hashing algorithm that maps the lower 19 bits from the user
109 or group RID to bits 0 - 19 in the Unix id and hashes 96 bits from
110 the domain SID to bits 20 - 30 in the Unix id. The result is a 31 bit
111 uid or gid that is consistent across machines and provides support for
114 Please refer to the idmap_hash(8) man page for more details.
120 The adex idmap/nss_info plugin is an adaptation of the Likewise
121 Enterprise plugin with support for OU based cells removed
122 (since the Windows pieces to manage the cells are not available).
126 * The RFC2307 schema for users and groups.
127 * Connections to trusted domains
128 * Global catalog searches
129 * Cross forest trusts
130 * User and group aliases
132 Prerequisite: Add the following attributes to the Partial Attribute
133 Set in global catalog:
139 A basic config using the current trunk code would look like:
143 idmap uid = 10000 - 29999
144 idmap gid = 10000 - 29999
145 winbind nss info = adex
147 winbind normalize names = yes
148 winbind refresh tickets = yes
149 template homedir = /home/%D/%U
150 template shell = /bin/bash
152 Please refer to the idmap_adex(8) man page for more details.
