<title>DESCRIPTION</title>
<para>
This manual page describes the configuration of the AD provider
for
<citerefentry>
<refentrytitle>sssd</refentrytitle>
<manvolnum>8</manvolnum>
</citerefentry>.
For a detailed syntax reference, refer to the <quote>FILE FORMAT</quote> section of the
<citerefentry>
<refentrytitle>sssd.conf</refentrytitle>
<manvolnum>5</manvolnum>
</citerefentry> manual page.
</para>
<para>
The AD provider is a back end used to connect to an Active
Directory server. This provider requires that the machine be
joined to the AD domain and a keytab is available.
</para>
<para>
The AD provider supports connecting to Active Directory 2008 R2
or later. Earlier versions may work, but are unsupported.
</para>
<para>
The AD provider accepts the same options used by the
<citerefentry>
<refentrytitle>sssd-ldap</refentrytitle>
<manvolnum>5</manvolnum>
</citerefentry> identity provider and the
<citerefentry>
<refentrytitle>sssd-krb5</refentrytitle>
<manvolnum>5</manvolnum>
</citerefentry> authentication provider with some exceptions described
below.
</para>
<para>
However, it is neither necessary nor recommended to set these
options. The AD provider can also be used as an access and chpass
provider. No configuration of the access provider is required on
the client side.
</para>
<para>
By default, the AD provider will map UID and GID values from the
objectSID parameter in Active Directory. For details on this, see
the <quote>ID MAPPING</quote> section below. If you want to
disable ID mapping and instead rely on POSIX attributes defined in
Active Directory, you should set
<programlisting>
ldap_id_mapping = False
</programlisting>
</para>
</refsect1>
<refsect1 id='file-format'>
<title>CONFIGURATION OPTIONS</title>
<para>Refer to the section <quote>DOMAIN SECTIONS</quote> of the
<citerefentry>
<refentrytitle>sssd.conf</refentrytitle>
<manvolnum>5</manvolnum>
</citerefentry> manual page for details on the configuration of an SSSD domain.
<variablelist>
<varlistentry>
<term>ad_domain (string)</term>
<listitem>
<para>
Specifies the name of the Active Directory domain.
This is optional. If not provided, the
configuration domain name is used.
</para>
<para>
For proper operation, this option should be
specified as the lower-case version of the long
version of the Active Directory domain.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>ad_server, ad_backup_server (string)</term>
<listitem>
<para>
The comma-separated list of IP addresses or
hostnames of the AD servers to which SSSD should
connect in order of preference. For more
information on failover and server redundancy, see
the <quote>FAILOVER</quote> section.
This is optional if autodiscovery is enabled.
For more information on service discovery, refer
to the <quote>SERVICE DISCOVERY</quote> section.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>ad_hostname (string)</term>
<listitem>
<para>
Optional. May be set on machines where the
hostname(5) does not reflect the fully qualified
name used in the Active Directory domain to
identify this host.
</para>
<para>
This field is used to determine the host principal
in use in the keytab. It must match the hostname
for which the keytab was issued.

<title>EXAMPLE</title>
<para>
The following example assumes that SSSD is correctly
configured and example.com is one of the domains in the
<replaceable>[sssd]</replaceable> section. This example shows only
the AD provider-specific options.
</para>
<para>
<programlisting>
[domain/EXAMPLE]
id_provider = ad
auth_provider = ad

<title>NOTES</title>
<para>
The AD access control provider checks if the account is expired.
It has the same effect as the following configuration of the LDAP
provider:
<programlisting>
access_provider = ldap
ldap_access_order = expire
ldap_account_expire_policy = ad
</programlisting>
