ทดสอบบน : Windows 2008 R2 / IIS 7.5
Code ดังนี้
Include Function ldappsu (ldappsu.php)

**** บทความเก่าเชื่อมต่อผ่าน ADLDAP ด้วย ubuntu 12.04/Apache2 ****
1. หลังจากติดตั้ง Apache2 และ เปิด Module php5-ldap เรียบร้อยแล้ว
2. ทำการโหลดโปรแกรม adLDAP จาก Website : http://adldap.sourceforge.net/download.php (สำหรับ PHP 4 ให้โหลด Version 2.1)
# cd /var/www
# wget http://downloads.sourceforge.net/project/adldap/adLDAP/adLDAP_4.0.4/adLDAP_4.0.4r2.zip
# unzip adLDAP_4.0.4r2.zip
3. เปิดหน้าตัวอย่างการเข้าใช้งานได้ที่ https://localhost/adLDAP/examples/authenticate.php
(สำหรับ Web ตัวอย่างต้องใช้เป็น https เท่านั้น)
4. ทำการแก้ไขไฟล์ /var/www/adLDAP/src/adLDAP.php บรรทัดเหล่านี้
…
protected $accountSuffix = “@psu.ac.th”;
…
protected $baseDn = “DC=psu,DC=ac,DC=th”;
…
protected $domainControllers = array(“dc2.psu.ac.th”,”dc7.psu.ac.th”,”dc1.psu.ac.th”);
…
protected $useSSL = true;
…
(สำหรับรายการ DC ให้เลือก DC ใกล้ที่สุดก่อน DC3-ปัตตานี, DC4-ภูเก็ต,DC5-สุราษฎร์,DC6-ตรัง,DC1,2,7-หาดใหญ่)
5. กลับมาเข้าที่ Web https://localhost/adLDAP/examples/authenticate.php อีกครั้งน่าจะสามารถใช้งานได้แล้ว
โดยสำหรับตัวนี้แนะนำว่าให้ใช้เฉพาะในส่วน authen เพราะในส่วนของการดึง Profile ยังค่อนข้างมีข้อจำกัด อยู่ ซึ่งถ้าอยากให้สามารถดึง Profile ได้ด้วย ผมแนะนำในส่วนของ Code ที่ผมเขียนขึ้นมาให้ โดยจะกล่าวในส่วนถัดไป
วิธีเรียกใช้งานไฟล์ Class AdLDAP (ให้ copy file จาก folder src ไปด้วย)
include “./adLDAP.php”
วิธีเรียกใช้ Class AdLDAP
try {
$adldap = new adLDAP();
}catch(adLDAPException $e){
echo $e;
exit();
}
วิธี Authentication
if($adldap->authenticate($username,$password)){
session_start();
$_SESSION[“username”] = $username;
…
}
