+<title>Group Mapping &smbmdash; MS Windows and UNIX</title>
+
+
+ <para>
+<indexterm significance="preferred"><primary>groups</primary><secondary>mapping</secondary></indexterm>
+ Starting with Samba-3, new group mapping functionality is available to create associations
+ between Windows group SIDs and UNIX groups. The <command>groupmap</command> subcommand
+ included with the &net; tool can be used to manage these associations.
+ </para>
+
+ <para>
+ The new facility for mapping NT Groups to UNIX system groups allows the administrator to decide
+ which NT Domain Groups are to be exposed to MS Windows clients. Only those NT Groups that map
+ to a UNIX group that has a value other than the default (<constant>-1</constant>) will be exposed
+ in group selection lists in tools that access domain users and groups.
+ </para>
+
+ <warning>
+ <para>
+ <indexterm><primary>domain admin group</primary></indexterm>
+ The <parameter>domain admin group</parameter> parameter has been removed in Samba-3 and should no longer
+ be specified in &smb.conf;. In Samba-2.2.x, this parameter was used to give the listed users membership in the
+ <constant>Domain Admins</constant> Windows group which gave local admin rights on their workstations
+ (in default configurations).
+ </para>
+ </warning>

+<sect1>

+ Samba allows the administrator to create MS Windows NT4/200x group accounts and to
+ arbitrarily associate them with UNIX/Linux group accounts.
+ </para>
+
+ <para>
+<indexterm><primary>UID</primary></indexterm>
+<indexterm><primary>GID</primary></indexterm>
+ Group accounts can be managed using the MS Windows NT4 or MS Windows 200x/XP Professional MMC tools.
+ Appropriate interface scripts should be provided in &smb.conf; if it is desired that UNIX/Linux system
+ accounts should be automatically created when these tools are used. In the absence of these scripts, and
+ so long as <command>winbindd</command> is running, Samba group accounts that are created using these
+ tools will be allocated UNIX UIDs/GIDs from the ID range specified by the
+ <smbconfoption><name>idmap uid</name></smbconfoption>/<smbconfoption><name>idmap gid</name></smbconfoption>
+ parameters in the &smb.conf; file.

+ Administrators should be aware that where &smb.conf; group interface scripts make
+ direct calls to the UNIX/Linux system tools (the shadow utilities, <command>groupadd</command>,
+ <command>groupdel</command>, and <command>groupmod</command>), the resulting UNIX/Linux group names will be subject
+ to any limits imposed by these tools. If the tool does not allow upper case characters
+ or space characters, then the creation of an MS Windows NT4/200x style group of
+ <ntgroup>Engineering Managers</ntgroup> will attempt to create an identically named
+ UNIX/Linux group, an attempt that will of course fail.
+ </para>
+
+
+
+ <para>
+ <indexterm><primary>GID</primary></indexterm>
+ <indexterm><primary>SID</primary></indexterm>
+ There are several possible work-arounds for the operating system tools limitation. One
+ method is to use a script that generates a name for the UNIX/Linux system group that
+ fits the operating system limits, and that then just passes the UNIX/Linux group ID (GID)
+ back to the calling Samba interface. This will provide a dynamic work-around solution.
+ </para>
+
+ <para>
+ Another work-around is to manually create a UNIX/Linux group, then manually create the
+ MS Windows NT4/200x group on the Samba server and then use the <command>net groupmap</command>
+ tool to connect the two to each other.

+ When installing <application>MS Windows NT4/200x</application> on a computer, the installation
+ program creates default users and groups, notably the <constant>Administrators</constant> group,
+ and gives that group privileges necessary privileges to perform essential system tasks,
+ such as the ability to change the date and time or to kill (or close) any process running on the
+ local machine.
+ </para>
+
+ <para>
+ <indexterm><primary>Administrator</primary></indexterm>
+ The <constant>Administrator</constant> user is a member of the <constant>Administrators</constant> group, and thus inherits
+ <constant>Administrators</constant> group privileges. If a <constant>joe</constant> user is created to be a member of the
+ <constant>Administrators</constant> group, <constant>joe</constant> has exactly the same rights as the user,
+ <constant>Administrator</constant>.
+ </para>
+
+ <para>
+ When an MS Windows NT4/200x/XP machine is made a Domain Member, the <quote>Domain Admins</quote> group of the
+ PDC is added to the local <constant>Administrators</constant> group of the workstation. Every member of the
+ <constant>Domain Administrators</constant> group inherits the rights of the local <constant>Administrators</constant> group when
+ logging on the workstation.
+ </para>

+ The following steps describe how to make Samba PDC users members of the <constant>Domain Admins</constant> group?

+ Add to this group the users that must be <quote>Administrators</quote>. For example,
+ if you want <constant>joe, john</constant> and <constant>mary</constant> to be administrators,

+ </para>
+
+ <para><programlisting>
+ domadm:x:502:joe,john,mary

+ </para></listitem>
+
+ <listitem><para>

+ <para>
+ <indexterm><primary>Domain Admins group</primary></indexterm>

+ Now <constant>joe, john</constant> and <constant>mary</constant> are domain administrators.

+ <para>
+ <indexterm><primary>groups</primary><secondary>domain</secondary></indexterm>
+ It is possible to map any arbitrary UNIX group to any Windows NT4/200x group as well as
+ making any UNIX group a Windows domain group. For example, if you wanted to include a
+ UNIX group (e.g., acct) in an ACL on a local file or printer on a Domain Member machine,
+ you would flag that group as a domain group by running the following on the Samba PDC:
+ </para>
+
+ <para>
+<screen>
+&rootprompt;<userinput>net groupmap add rid=1000 ntgroup="Accounting" unixgroup=acct</userinput>
+</screen>
+ </para>
+
+ <para>
+ Be aware that the RID parameter is a unsigned 32-bit integer that should
+ normally start at 1000. However, this RID must not overlap with any RID assigned
+ to a user. Verification for this is done differently depending on the passdb backend
+ you are using. Future versions of the tools may perform the verification automatically,
+ but for now the burden is on you.

+ Administrative tasks on UNIX/Linux systems, such as adding users or groups, requires <constant>root</constant>
+ level privilege. The addition of a Windows client to a Samba Domain involves the addition of a user account
+ for the Windows client.
+ </para>
+
+ <para>
+ Many UNIX administrators continue to request the Samba Team make it possible to add Windows workstations, or
+ to ability to add/delete or modify user accounts, without requiring <constant>root</constant> privileges.
+ Such a request violates every understanding of basic UNIX system security.
+ </para>
+
+ <para>
+ There is no safe way to provide access on a UNIX/Linux system without providing <constant>root</constant>
+ level privilege. Provision of <constant>root</constant> privileges can be done either by logging onto
+ the Domain as the user <constant>root</constant>, or by permitting particular users to use a UNIX account
+ that is a member of the UNIX group that has a GID=0 as the primary group in the <filename>/etc/passwd</filename>
+ database. Users of such accounts can use tools like the NT4 Domain User Manager, and the NT4 Domain Server
+ Manager to manage user and group accounts as well as Domain Member server and client accounts. This level
+ of privilege is also needed to manage share level ACLs.
+ </para>
+
+ <para>
+ Administrative tasks on a Windows Domain Member workstation, can be done by anyone who is a member of the
+ <constant>Domain Admins</constant> group. This group can be mapped to any convenient UNIX group.

+ When first installed, Microsoft Windows NT4/200x/XP are pre-configured with certain User, Group, and
+ Alias entities. Each has a well-known Relative Identifier (RID). These must be preserved for continued
+ integrity of operation. Samba must be provisioned with certain essential Domain Groups that require
+ the appropriate RID value. When Samba-3 is configured to use <constant>tdbsam</constant> the essential
+ Domain Groups are automatically created. It is the LDAP administrators' responsibility to create
+ (provision) the default NT Groups.

+ Each essential Domain Group must be assigned its respective well-known RID. The default Users, Groups,

+ It is permissible to create any Domain Group that may be necessary, just make certain that the essential
