PHP LDAP获取组的成员

<?php
// LDAP服务器信息
$ldapServer = 'ldap://ldap.example.com';
$ldapPort = 389;
$ldapUser = 'cn=admin,dc=example,dc=com';
$ldapPassword = 'password';

// 连接LDAP服务器
$ldapConn = ldap_connect($ldapServer, $ldapPort);
ldap_set_option($ldapConn, LDAP_OPT_PROTOCOL_VERSION, 3);

if ($ldapConn) {
    // 绑定管理员账号
    $ldapBind = ldap_bind($ldapConn, $ldapUser, $ldapPassword);

    if ($ldapBind) {
        // 获取组的成员列表

        $result = ldap_search($ldapConn, $groupDN, '(objectClass=*)', ['member']);
        $entries = ldap_get_entries($ldapConn, $result);

        if ($entries['count'] > 0) {
            // 遍历成员列表
            for ($i = 0; $i < $entries['count']; $i++) {
