        <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>
            Users, groups and other entities served by SSSD are always treated as
            case-insensitive in the AD provider for compatibility with Active
            Directory's LDAP implementation.
        </para>

            The AD access control provider checks if the account is expired.
            It has the same effect as the following configuration of the LDAP
