Question

我想使用Active Directory为我们公司创建一个目录Intranet网站。到目前为止我得到了这个，但是当我在调试模式下运行时，代码在searchResultCollection....search.findAll();中显示：

[DirectoryServicesCOMException（0x80072020）：发生操作错误。]

我已尝试将IIS asp.net模拟更改为已启用，但我收到HTTP错误500.24。我的用户名具有对Active Directory的读访问权限。是否有一些我缺少的东西，或者有人指出我正确的方向。我到处都看，这是我被卡住了。

提前感谢您的帮助。

您可以使用PrincipalSearcher和＆＃34;按示例查询＆＃34;负责你的搜索：

// create your domain context
using (PrincipalContext ctx = new PrincipalContext(ContextType.Domain))
{
   // define a "query-by-example" principal - here, we search for a UserPrincipal 
   // and with the first name (GivenName) of "Bruce" and a last name (Surname) of "Miller"
   UserPrincipal qbeUser = new UserPrincipal(ctx);
   qbeUser.GivenName = "Bruce";
   qbeUser.Surname = "Miller";

   // create your principal searcher passing in the QBE principal    
   PrincipalSearcher srch = new PrincipalSearcher(qbeUser);

   // find all matches
   foreach(var found in srch.FindAll())
   {
       // do whatever here - "found" is of type "Principal" - it could be user, group, computer.....          
   }
}

如果您还没有 - 绝对阅读MSDN文章Managing Directory Security Principals in the .NET Framework 3.5，该文章很好地展示了如何充分利用System.DirectoryServices.AccountManagement中的新功能。或者查看MSDN documentation on the System.DirectoryServices.AccountManagement命名空间。

当然，根据您的需要，您可能希望在其上指定其他属性＆＃34;按示例查询＆＃34;您创建的用户主体：

DisplayName（通常：名字+空格+姓氏）
SAM Account Name - 您的Windows / AD帐户名称
User Principal Name - 您的＆＃34; username@yourcompany.com"样式名称

您可以在UserPrincipal上指定任何属性，并将其用作＆＃34;按示例查询＆＃34;为您的PrincipalSearcher。

自我重新启动后，我再次测试它运行没有错误然后添加其余代码以在gridview中显示。

 public partial class _Default : System.Web.UI.Page
 {
 protected void Page_Load(object sender, EventArgs e)
 {
      if (!Page.IsPostBack)
         GetADUsers();
  }

  public void GetADUsers()
  {
      DirectoryEntry myLdap = new DirectoryEntry("LDAP://OU=Nix,DC=systems,DC=com");
      DirectorySearcher search = new DirectorySearcher(myLdap);
      search.CacheResults = true;
      search.SearchScope = SearchScope.Subtree;
      search.Filter = "(objectlass=person)";
      SearchResultCollection allResults = search.FindAll();
      search.PropertiesToLoad.Add("samaccountname");

      Grid1.DataSource = allResults;
      Grid1.DataBind();
 }
