2 Release Notes for Samba 3.3.0
4 =============================
6 This is the first stable release of Samba 3.3.0.
8 Major enhancements in Samba 3.3.0 include:
11 o The passdb tdbsam version has been raised.
13 Configuration/installation:
14 o Splitting of library directory into library directory and separate
16 o The default value of "ldap ssl" has been changed to "start tls".
19 o Extended Cluster support.
20 o New experimental VFS modules "vfs_acl_xattr" and "vfs_acl_tdb"
21 to store NTFS ACLs on Samba file servers.
24 o Simplified idmap configuration.
25 o New idmap backends "adex" and "hash".
26 o Added new parameter "winbind reconnect delay".
27 o Added support for user and group aliasing.
28 o Added support for multiple domains to idmap_ad.
31 o The destination "all" of smbcontrol does now affect all running
32 daemons including nmbd and winbindd.
33 o New 'net rpc vampire keytab' and 'net rpc vampire ldif' commands.
34 o The 'net' utility can now use kerberos for joining and authentication.
35 o The 'wbinfo' utility can now add, modify and remove identity mapping entries.
38 o NetApi library implements various new calls for User- and Group
45 The passdb tdbsam version has been raised as among other things the RID counter
46 has been moved from the winbindd_idmap.tdb to the passdb.tdb file to make
47 "passdb backend = tdbsam" working in clustered environments.
49 Please note that an updated passdb.tdb file is _not_ compatible with Samba
50 versions before 3.3.0! Please backup your passdb.tdb file if
51 you use "passdb backend = tdbsam". That can be achieved by running
53 'tdbbackup /etc/samba/passdb.tdb'
61 The configure option "--with-libdir" has been removed. The library
62 directory can still be specified by using the existing "--libdir" option.
63 A new option "--with-modulesdir" has been added to allow the specification
64 of a separate directory for the shared modules.
70 The default value of "ldap ssl" has been changed to "start tls". This means,
71 Samba will use the LDAPv3 StartTLS extended operation (RFC2830) for
72 communicating with directory servers by default. If your directory servers
73 do not support this extended operation, you will have to set
74 "ldap ssl = no". Otherwise, Samba could not contact the directory servers
78 Winbind idmap backend changes
79 =============================
81 The idmap configuration has changed with version 3.3 to something that
82 allows a smoother upgrade path from pre-3.0.25 configurations that use
83 "idmap backend". The reason for this change is that to many, also to Samba
84 developers, the 3.0.25 style configuration with "idmap config" turned out
85 to be very complex. Version 3.3 no longer deprecates the "idmap backend"
86 parameter, instead with "idmap backend" the default idmap backend is
89 Accordingly, the "idmap config <domain> : default = yes" setting is no
90 longer being looked at.
92 The alloc backend defaults to the default backend, which should be able to
93 allocate IDs. In the default distribution the tdb and ldap backends can
94 allocate, the ad and rid backends can not. The idmap alloc range is now
95 being set with the "old" parameters "idmap uid" and "idmap gid".
97 The "idmap domains" parameter has been removed.
100 winbind reconnect delay
101 =======================
103 This is a new parameter which specifies the number of seconds the Winbind
104 daemon will wait between attempts to contact a Domain controller for a domain
105 that is determined to be down or not contactable.
108 Winbind's Name Aliasing
109 =======================
111 Name aliasing in Winbind is a feature that allows an administrator to
112 map a fully qualified user or group name from a Windows domain to a
113 convenient short name for Unix access. This is similar to the username
114 map functionality supported by smbd but is primary intended for
115 clients and servers making use of Winbind's PAM and NSS libraries.
117 For example, the user "DOMAIN\fred" has been mapped to the Unix name
120 $ getent passwd "DOMAIN\fred"
121 freddie:x:1000:1001:Fred Jones:/home/freddie:/bin/bash
123 $ getent passwd freddie
124 freddie:x:1000:1001:Fred Jones:/home/freddie:/bin/bash
126 The name aliasing support is provided by individual nss_info plugins.
127 For example, the new "adex" plugin reads the uid attribute from Active
128 Directory to make a short login name to the fully qualified name.
129 While the new "hash" module utilizes a local file to map "short_name
130 = QUALIFIED\name". Both user and group name mapping is supported.
131 Please refer to the "winbind nss info" option in smb.conf(5) and
132 to individual plugin man pages for further details.
138 The idmap_hash plugin provides similar support as the idmap_rid
139 module. However, uids and gids are generated from the full domain
140 SID using a hashing algorithm that maps the lower 19 bits from the user
141 or group RID to bits 0 - 19 in the Unix id and hashes 96 bits from
142 the domain SID to bits 20 - 30 in the Unix id. The result is a 31 bit
143 uid or gid that is consistent across machines and provides support for
146 Please refer to the idmap_hash(8) man page for more details.
152 The adex idmap/nss_info plugin is an adaptation of the Likewise
153 Enterprise plugin with support for OU based cells removed
154 (since the Windows pieces to manage the cells are not available).
158 * The RFC2307 schema for users and groups.
159 * Connections to trusted domains
160 * Global catalog searches
161 * Cross forest trusts
162 * User and group aliases
164 Prerequisite: Add the following attributes to the Partial Attribute
165 Set in global catalog:
171 A basic config using the current trunk code would look like:
175 idmap uid = 10000 - 29999
176 idmap gid = 10000 - 29999
177 winbind nss info = adex
179 winbind normalize names = yes
180 winbind refresh tickets = yes
181 template homedir = /home/%D/%U
182 template shell = /bin/bash
184 Please refer to the idmap_adex(8) man page for more details.
