openladp的创建和连接

1.下载openladp：在这里下载：
http://www.userbooster.de/download/openldap-for-windows.aspx
下载完后，一路next即可（有个地方选bdb即可）。记住这个就行：

openLDAP-win-05.jpg openLDAP-win-06.jpg

2.这个完事，然后下载LdapBrowser282.
地址在：
http://www.micmiu.com/wp-content/uploads/2012/05/LdapBrowser282.zip
然后如下操作：

openLDAP-browser-01.jpg openLDAP-browser-03.jpg openLDAP-browser-04.jpg

3.在添加一项：
password为123

无标题1.png

这样添加完毕了。

4.写C#代码验证：直接拿过来就能用

namespace WindowsFormsApplication3
{
public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        string TestUserID = "cn=newperson,ou=People,dc=maxcrc,dc=com";
