================================ Release Notes for Samba 3.3.0rc1 ================================ 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: Configuration/installation: o Splitting of library directory into library directory and separate modules directory. File Serving: o Extended Cluster support. Winbind: 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. Libraries: 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 specified. Accordingly, the "idmap config : 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 "freddie". $ 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. idmap_hash ========== 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. idmap_adex ========== 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: [global] 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. ###################################################################### Changes ####### smb.conf changes ---------------- Parameter Name Description Default -------------- ----------- ------- cups connection timeout New 30 idmap domains Removed init logon delayed hosts New "" init logon delay New 100 winbind reconnect delay New 30 Changes since 3.3.0pre2: ------------------------ o Jeremy Allison * BUG 5080: Fix access to cups-printers with cups 1.3.4. * BUG 5814: Fix Winbind crash bug while doing "rescan_trusted_domain". * BUG 5818: Sort ACEs in smbcacl output properly and honor inheritance. * BUG 5826: Fix truncated filenames when accessing old servers. * Correctly fix smbclient to terminate on eof from server. * Fix client timeout when searching for a large number of cups printers. * Unify access checks for lsa server functions. * Remove the requirement for ldap call made as root. * Cope with MAXIMUM_ALLOWED_ACCESS requests when opening handles. * Fix net rpc vampire, based on an *amazing* piece of debugging work by "Cooper S.
