	<title>DESCRIPTION</title>

	<para>The idmap_rfc2307 plugin provides a way for winbind to
	read id mappings from records in an LDAP server as defined in
	RFC 2307. The LDAP server can be stand-alone or the LDAP
	server provided by the AD server. An AD server is always
	required to provide the mapping between name and SID, and the
	LDAP server is queried for the mapping between name and
	uid/gid. This module implements only the &quot;idmap&quot;
	API, and is READONLY.</para>

	<para>Mappings must be provided in advance by the
	administrator by creating the user accounts in the Active
	Directory server and the posixAccount and posixGroup objects
	in the LDAP server. The names in the Active Directory server
	and in the LDAP server have to be the same.</para>

	<para>This id mapping approach allows the reuse of existing
	LDAP authentication servers that store records in the RFC 2307
	format.</para>

	<para>When connecting to the LDAP server provided by an AD
	server, the parameter <smbconfoption name="ldap ssl ads"/>
	determines whether SSL should be used. When using a
	stand-alone LDAP server, <smbconfoption name="ldap ssl"/>
	applies.</para>

	<title>IDMAP OPTIONS</title>

	<variablelist>
		<varlistentry>
			<term>range = low - high</term>
			<listitem><para> Defines the available
			matching UID and GID range for which the
			backend is authoritative. Note that the range
			acts as a filter. If specified any UID or GID
			stored in AD that fall outside the range is
			ignored and the corresponding map is
			discarded. It is intended as a way to avoid
			accidental UID/GID overlaps between local and
			remotely defined IDs.</para></listitem>
		</varlistentry>
		<varlistentry>
			<term>ldap_server = &lt;ad | stand-alone &gt;</term>
			<listitem><para>Defines the type of LDAP
			server to use. This can either be the LDAP
			server provided by the Active Directory server
			(ad) or a stand-alone LDAP
			server.</para></listitem>
		</varlistentry>
		<varlistentry>
			<term>bind_path_user</term>
			<listitem><para>Specifies the search base where
			user objects can be found in the LDAP
			server.</para></listitem>
		</varlistentry>
		<varlistentry>
			<term>bind_path_group</term>
			<listitem><para>Specifies the search base where
			group objects can be found in the LDAP
			server.</para></listitem>
		</varlistentry>
		<varlistentry>
			<term>user_cn = &lt;yes | no&gt;</term>
			<listitem><para>Query cn attribute instead of
			uid attribute for the user name in LDAP. This
			option is not required, the default is
			no.</para></listitem>
		</varlistentry>
		<varlistentry>
			<term>realm</term>
			<listitem><para>Append @realm to cn for groups
			(and users if user_cn is set) in
			LDAP queries. This option is not required, the default
			is not to append the realm.</para></listitem>
		</varlistentry>
		<varlistentry>
			<term>ldap_domain</term>
			<listitem><para>When using the LDAP server in
			the Active Directory server, this allows one to
			specify the domain where to access the Active
			Directory server. This allows using trust
			relationships while keeping all RFC 2307
			records in one place. This parameter is
			optional, the default is to access the AD
			server in the current domain to query LDAP
			records.</para></listitem>
		</varlistentry>
		<varlistentry>
			<term>ldap_url</term>
			<listitem><para>When using a stand-alone LDAP
			server, this parameter specifies the ldap URL
			for accessing the LDAP
			server.</para></listitem>
		</varlistentry>
		<varlistentry>
			<term>ldap_user_dn</term>
			<listitem><para>Defines the user DN to be used
			for authentication.  The secret for
			authenticating this user should be stored with
			net idmap secret (see
			<citerefentry><refentrytitle>net</refentrytitle>
			<manvolnum>8</manvolnum></citerefentry>). If
			absent, an anonymous bind will be
			performed.</para></listitem>

	<title>EXAMPLES</title>

	<para>The following example shows how to retrieve id mappings
	from a stand-alone LDAP server.  This example also shows how
	to leave a small non conflicting range for local id allocation
	that may be used in internal backends like BUILTIN.</para>

	<programlisting>
	[global]
	idmap config * : backend = tdb
	idmap config * : range = 1000000-1999999

	idmap config DOMAIN : backend = rfc2307
	idmap config DOMAIN : range = 2000000-2999999
	idmap config DOMAIN : ldap_server = stand-alone
	idmap config DOMAIN : ldap_url = ldap://ldap1.example.com
	idmap config DOMAIN : ldap_user_dn = cn=ldapmanager,dc=example,dc=com
	idmap config DOMAIN : bind_path_user = ou=People,dc=example,dc=com
	idmap config DOMAIN : bind_path_group = ou=Group,dc=example,dc=com

	<title>AUTHOR</title>

	<para>
	The original Samba software and related utilities
	were created by Andrew Tridgell. Samba is now developed
	by the Samba Team as an Open Source project similar
	to the way the Linux kernel is developed.
