    Here's some custom code that might help you achieve that:

    add_filter('user_sync_custom_sql', 'user_sync_roles', 999);
    function user_sync_roles($sql) {
        global $wpdb;
        $roles = array('administrator','editor');
        $sql = "SELECT ID FROM {$wpdb->users} INNER JOIN {$wpdb->usermeta} ON {$wpdb->users}.ID = {$wpdb->usermeta}.user_id
            WHERE {$wpdb->usermeta}.meta_key = '{$wpdb->prefix}capabilities'
            AND ( ";
        $i = 1;
        foreach($roles as $role) {
            $sql .= "{$wpdb->usermeta}.meta_value LIKE '%{$role}%'";
            if($i < count($roles)) {
                $sql .= " OR ";
        $sql .= " ) ";
        return $sql;

    You can create a php file in your site directory under "/wp-content/mu-plugins" and add the code in it. The role you want sync can be added to the roles array inside this portion of the code, separated by commas:
    $roles = array('administrator','editor','subscriber','author');

    Do let us know if you have any question on that .
