ldad ad ldap_control_paged_result php ldap_get_entries 最大条目数 max 只有一千一万 1000 10000 如何让条目数超过 10000 使用分页功能 page pages pagination 有大用 有大大用 有大大大用

我自己实现的代码如下 主要代码见下面的红色部分:

function _get_all_ad_infos_from_ad($diqu = 'js')
{
    $ad_connect_infos = _my_get_ad_connect_infos();
    $ad_user = $ad_connect_infos[$diqu]['ad_user']; //域用户名 包含域名
    $ad_pwd = $ad_connect_infos[$diqu]['ad_pwd'];
    $host = $ad_connect_infos[$diqu]['host'];
    $port = $ad_connect_infos[$diqu]['port'];//一般都是389

    $conn = ldap_connect($host, $port); //不要写成ldap_connect($host.':'.$port)的形式
    if ($conn) {
        //设置参数
        ldap_set_option($conn, LDAP_OPT_PROTOCOL_VERSION, 3); //声明使用版本3
        ldap_set_option($conn, LDAP_OPT_REFERRALS, 0); // Binding to ldap server
        $bd = ldap_bind($conn, $ad_user, $ad_pwd);

        $basedn = $ad_connect_infos[$diqu]['basedn'];
        if($_GET['q'] == 'list_ad_users' && $_GET['update_from_ad'] ==1 && $diqu='js'){
            $basedn = 'ou=JS-Site,ou=立讯集团,dc=luxshare,dc=com,dc=cn';
        }
        // $filter = "(objectClass=*)";//选择器
        // $filter = "(&(sAMAccountName=史平忠))";//选择器
//    $filter = "SamAccountName=" . $gh; //根据工号 比如 16666739
        $filter = "SamAccountName=*"; //*星号表示取所有
        //$filter="(|(sn=史平忠*)(givenname=史平忠*))";
//    $justthese = array('*'); //选择要获取的用户属性
        $justthese = array('samaccountname', 'displayname', 'mail', 'telephonenumber', 'department', 'memberof', 'lockouttime', 'manager', 'directreports', 'memberof'); //选择要获取的用户属性
        $pageSize = 5000;
      $cookie = '';
      $infos =  array();
        do {
            ldap_control_paged_result($conn, $pageSize, true, $cookie);
            $sr = ldap_search($conn, $basedn, $filter, $justthese);
            $tmp_infos = ldap_get_entries($conn, $sr);
            $infos = array_merge($infos, $tmp_infos);
            ldap_control_paged_result_response($conn, $sr, $cookie);
        } while($cookie !== null && $cookie != '');

        if ($bd) {
            //drupal_set_message('LDAP 连接成功'); //相当于登录成功
        } else {
            $infos = false;
            drupal_set_message('LDAP 连接失败', 'warning');
        }
    } else {
        $infos = false;
        drupal_set_message('无法连接到AD域服务器', 'error');
    }
    ldap_close($conn);
    return $infos;
}



ldap_control_paged_result


(PHP 5 >= 5.4.0, PHP 7)

ldap_control_paged_result — Send LDAP pagination control

警告

This function has been DEPRECATED as of PHP 7.4.0, and REMOVED as of PHP 8.0.0. Instead the controls parameter of ldap_search() should be used. See also LDAP Controls for details.

说明 ¶

ldap_control_paged_result(
    resource $link,
    int $pagesize,
    bool $iscritical = false,
    string $cookie = ""
): bool

Enable LDAP pagination by sending the pagination control (page size, cookie...).

参数 ¶

  • link

  • An LDAP resource, returned by ldap_connect().

  • pagesize

  • The number of entries by page.

  • iscritical

  • Indicates whether the pagination is critical or not. If true and if the server doesn't support pagination, the search will return no result.

  • cookie

  • An opaque structure sent by the server (ldap_control_paged_result_response()).

返回值 ¶

成功时返回 true， 或者在失败时返回 false。

更新日志 ¶

版本说明
8.0.0This function has been removed.
7.4.0This function has been deprecated.

示例 ¶

The example below show the retrieval of the first page of a search paginated with one entry by page.

示例 #1 LDAP pagination

<?php
    // $ds is a valid link identifier (see ldap_connect)
    ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3);

    $dn        = 'ou=example,dc=org';
    $filter    = '(|(sn=Doe*)(givenname=John*))';
    $justthese = array('ou', 'sn', 'givenname', 'mail');

    // enable pagination with a page size of 1.
    ldap_control_paged_result($ds, 1);

    $sr = ldap_search($ds, $dn, $filter, $justthese);

    $info = ldap_get_entries($ds, $sr);

    echo $info['count'] . ' entries returned' . PHP_EOL;

The example below show the retrieval of all the result paginated with 100 entries by page.

示例 #2 LDAP pagination

<?php
    // $ds is a valid link identifier (see ldap_connect)
    ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3);

    $dn        = 'ou=example,dc=org';
    $filter    = '(|(sn=Doe*)(givenname=John*))';
    $justthese = array('ou', 'sn', 'givenname', 'mail');

    // enable pagination with a page size of 100.
    $pageSize = 100;

    $cookie = '';
    do {
        ldap_control_paged_result($ds, $pageSize, true, $cookie);

        $result  = ldap_search($ds, $dn, $filter, $justthese);
        $entries = ldap_get_entries($ds, $result);
           
        foreach ($entries as $e) {
            echo $e['dn'] . PHP_EOL;
        }

        ldap_control_paged_result_response($ds, $result, $cookie);
     
    } while($cookie !== null && $cookie != '');

注释 ¶

注意:

Pagination control is a LDAPv3 protocol feature.

If you did a paged search operation and want to do any other read operation on LDAP, you need to reset it, otherwise you will experience LDAP errors (code 12, for instance).

<?php
…
ldap_control_paged_result($link, 0);
…
?>

I was able to get these functions to work successfully with Active Directory.  When I first tried it, ldap_search kept returning a Not Supported reply from the server.  I finally figured out that I needed to include

ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3);

in my code, so that AD would let me page results.  Make sure you're using a compatible protocol.

Hope this note helps someone else.

While another note suggests resetting the control paged result by passing in `0` (zero), it actually still prevents any further queries being ran during the same request.

You actually need to set it to a large number to run further queries it seems. For example:

<?php
ldap_control_paged_result($connection, 100, true, $cookie);

// Run the search
...

// What is supposed to work (reset)
ldap_control_paged_result($connection, 0, false, $cookie);

// What actually works
ldap_control_paged_result($connection, 1000, false, $cookie);
?>

In the above method, 1000 is just a placeholder, but this seems to actually **limit** further queries to this amount of results, so if you set it to `1`, then you'll only receive **one** result for any further queries during the same request.

You may need to do an ldap_bind before running ldap_control_paged_result to get this to work:

$conn = ldap_connect("you_ip");
ldap_set_option($conn, LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_bind("your_connection_info");       
ldap_control_paged_result($conn, $pageSize, true, $cookie)

Without doing an ldap_bind, I kept getting the error "Critical extension is unavailable". I don't if this is standard knowledge, but knowing this would have saved me days of frustration.

So how do you now sort the entire result? It appears you can't use ldap_sort as it uses the search resource which is within the loop.

Paged results, as specified in the RFC 2696, does not allow to get over the server sizeLimit. The RFC clearly states "If the page size is greater than or equal to the sizeLimit value, the server should ignore the control as the request can be satisfied in a single page".
With OpenLDAP, you will not get more than the sizeLimit number of entries with paged results.
