            to authenticate against an LDAP server either TLS/SSL or LDAPS

                    <listitem>
                        <para>
                            Specifies the Schema Type in use on the target LDAP
                            server.
                            Depending on the selected schema, the default
                            attribute names retrieved from the servers may vary.
                            The way that some attributes are handled may also differ.

                            Four schema types are currently supported:
                            rfc2307
                            rfc2307bis
                            IPA
                            AD

                            The main difference between these schema types is
                            how group memberships are recorded in the server.
                            With rfc2307, group members are listed by name in the
                            <emphasis>memberUid</emphasis> attribute.
                            With rfc2307bis and IPA, group members are listed by DN
                            and stored in the <emphasis>member</emphasis> attribute.
                            The AD schema type sets the attributes to correspond with
                            Active Directory 2008r2 values.

                            Please note that sssd only supports referral chasing
                            when it is compiled with OpenLDAP version 2.4.13 or

                            Chasing referrals may incur a performance penalty
                            in environments that use them heavily, a notable
                            example is Microsoft Active Directory. If
                            your setup does not in fact require the use
                            of referrals, setting this option to false
                            might bring a noticeable performance improvement.
