2 Release Notes for Samba 3.3.0rc2
4 ================================
6 This is the second 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.
25 o Added support for multiple domains to idmap_ad.
28 o The destination "all" of smbcontrol does now affect all running
29 daemons including nmbd and winbindd.
30 o New 'net rpc vampire keytab' and 'net rpc vampire ldif' commands.
31 o The 'net' utility can now use kerberos for joining and authentication.
32 o The 'wbinfo' utility can now add, modify and remove identity mapping entries.
35 o NetApi library implements various new calls for User- and Group
42 The configure option "--with-libdir" has been removed. The library
43 directory can still be specified by using the existing "--libdir" option.
44 A new option "--with-modulesdir" has been added to allow the specification
45 of a separate directory for the shared modules.
48 Winbind idmap backend changes
49 =============================
51 The idmap configuration has changed with version 3.3 to something that
52 allows a smoother upgrade path from pre-3.0.25 configurations that use
53 "idmap backend". The reason for this change is that to many, also to Samba
54 developers, the 3.0.25 style configuration with "idmap config" turned out
55 to be very complex. Version 3.3 no longer deprecates the "idmap backend"
56 parameter, instead with "idmap backend" the default idmap backend is
59 Accordingly, the "idmap config <domain> : default = yes" setting is no
60 longer being looked at.
62 The alloc backend defaults to the default backend, which should be able to
63 allocate IDs. In the default distribution the tdb and ldap backends can
64 allocate, the ad and rid backends can not. The idmap alloc range is now
65 being set with the "old" parameters "idmap uid" and "idmap gid".
67 The "idmap domains" parameter has been removed.
70 winbind reconnect delay
71 =======================
73 This is a new parameter which specifies the number of seconds the Winbind
74 daemon will wait between attempts to contact a Domain controller for a domain
75 that is determined to be down or not contactable.
78 Winbind's Name Aliasing
79 =======================
81 Name aliasing in Winbind is a feature that allows an administrator to
82 map a fully qualified user or group name from a Windows domain to a
83 convenient short name for Unix access. This is similar to the username
84 map functionality supported by smbd but is primary intended for
85 clients and servers making use of Winbind's PAM and NSS libraries.
87 For example, the user "DOMAIN\fred" has been mapped to the Unix name
90 $ getent passwd "DOMAIN\fred"
91 freddie:x:1000:1001:Fred Jones:/home/freddie:/bin/bash
93 $ getent passwd freddie
94 freddie:x:1000:1001:Fred Jones:/home/freddie:/bin/bash
96 The name aliasing support is provided by individual nss_info plugins.
97 For example, the new "adex" plugin reads the uid attribute from Active
98 Directory to make a short login name to the fully qualified name.
99 While the new "hash" module utilizes a local file to map "short_name
100 = QUALIFIED\name". Both user and group name mapping is supported.
101 Please refer to the "winbind nss info" option in smb.conf(5) and
102 to individual plugin man pages for further details.
108 The idmap_hash plugin provides similar support as the idmap_rid
109 module. However, uids and gids are generated from the full domain
110 SID using a hashing algorithm that maps the lower 19 bits from the user
111 or group RID to bits 0 - 19 in the Unix id and hashes 96 bits from
112 the domain SID to bits 20 - 30 in the Unix id. The result is a 31 bit
113 uid or gid that is consistent across machines and provides support for
116 Please refer to the idmap_hash(8) man page for more details.
122 The adex idmap/nss_info plugin is an adaptation of the Likewise
123 Enterprise plugin with support for OU based cells removed
124 (since the Windows pieces to manage the cells are not available).
128 * The RFC2307 schema for users and groups.
129 * Connections to trusted domains
130 * Global catalog searches
131 * Cross forest trusts
132 * User and group aliases
134 Prerequisite: Add the following attributes to the Partial Attribute
135 Set in global catalog:
141 A basic config using the current trunk code would look like:
145 idmap uid = 10000 - 29999
146 idmap gid = 10000 - 29999
147 winbind nss info = adex
149 winbind normalize names = yes
150 winbind refresh tickets = yes
151 template homedir = /home/%D/%U
152 template shell = /bin/bash
154 Please refer to the idmap_adex(8) man page for more details.
