            The IPA provider is a back end used to connect to an IPA server.
            (Refer to the freeipa.org web site for information about IPA servers.)
            This provider requires that the machine be joined to the IPA domain;
            configuration is almost entirely self-discovered and obtained
            directly from the server.
        </para>
        <para>
            The IPA provider accepts the same options used by the
            <citerefentry>

            </citerefentry> authentication provider with some exceptions described
            below.
        </para>
        <para>
            However, it is neither necessary nor recommended to set these options.
            IPA provider can also be used as an access and chpass provider. As an
            access provider it uses HBAC (host-based access control) rules. Please
            refer to freeipa.org for more information about HBAC. No configuration
            of access provider is required on the client side.
