代码展示

连接ldap

    public function connect(){
        self::$connect = ldap_connect($this->account,$this->port);
        
        ldap_set_option(self::$connect,LDAP_OPT_PROTOCOL_VERSION,3);
        ldap_set_option(self::$connect, LDAP_OPT_REFERRALS, 0);
  
        $bind = ldap_bind(self::$connect,'用户名','密码');
        if ($bind){
            return true;
        }else{
            return false;
        }
    }

ldap过滤搜索

    public function ldapFilter($baseDn,$filter){
        $read = ldap_search(self::$connect,$baseDn,$filter);
 
        var_dump(ldap_error(self::$connect));//输出错误日志
 
        //该结果需要手动处理下（返回自己有用的信息）
        $data = ldap_get_entries(self::$connect, $read); //获取结果数组
        if (!$data){
      
            return [];
        }
        return $data;
    }

处理windows限制1000条，优化获取数据

    //处理windows限制1000条数据（进行分段读取）
    public function ldapFilter($baseDn,$filter)
    {
        $data = [];
        $cookie = '';
        do {
            $result = ldap_search(
                self::$connect, $baseDn, $filter, [], 0, 0, 0, LDAP_DEREF_NEVER,
                [['oid' => LDAP_CONTROL_PAGEDRESULTS, 'value' => ['size' => 750, 'cookie' => $cookie]]]
            );
            ldap_parse_result(self::$connect, $result, $errcode , $matcheddn , $errmsg , $referrals, $controls);
            // To keep the example short errors are not tested
            $entries = ldap_get_entries(self::$connect, $result);
 
            //array_shift($entries);
            $data = array_merge($data, $entries);
//            var_dump(count($data) . $filter);
 
            if (isset($controls[LDAP_CONTROL_PAGEDRESULTS]['value']['cookie'])) {
                // You need to pass the cookie from the last call to the next one
                $cookie = $controls[LDAP_CONTROL_PAGEDRESULTS]['value']['cookie'];
            } else {
                $cookie = '';
            }
            // Empty cookie means last page
        } while (!empty($cookie));
 
        if (!$data){ 
            return [];
        }
        return $data;
    }
