                            Specifies the URI of the LDAP server to which
                            SSSD should connect.

                <varlistentry>
                    <term>ldap_schema (string)</term>
                    <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.
                            Also the way some attributes are handled may differ.

                            There are currently 2 schema types supported:
                            rfc2307
                            rfc2307bis

                            The main difference between these 2 schema types is
                            how group memberships are recorder in the server.
                            With rfc2307 group members are listed by name in an
                            attribute called <emphasis>memberUid</emphasis>.
                            With rfc2307bis grpoup members are listed by DN and
                            stored in an attribute called
                            <emphasis>member</emphasis>.
