C# asp.net上的active directory用户_C#_Asp.net_Iis 7_Active Directory_Ldap - Fatal编程技术网

C# asp.net上的active directory用户

C# asp.net上的active directory用户,c#,asp.net,iis-7,active-directory,ldap,C#,Asp.net,Iis 7,Active Directory,Ldap,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,我已经了解了这一点,但是当我在调试模式下运行时,代码在searchResultCollection….search.findAll()中中断显示: [DirectoryServicesCOMException(0x80072020):发生操作错误。] 我已尝试将IIS asp.net模拟更改为启用,但出现HTTP错误500.24。 我的用户名具有对Active Directory的读取权限。是否有什么

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,我已经了解了这一点,但是当我在调试模式下运行时,代码在
searchResultCollection….search.findAll()中中断显示:

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

我已尝试将IIS asp.net模拟更改为启用,但出现HTTP错误500.24。 我的用户名具有对Active Directory的读取权限。是否有什么东西我错过了,或者有人能给我指出正确的方向。我到处都找过了,我被卡住了

提前感谢您的帮助

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data;
using System.DirectoryServices;
using System.Web.Security;

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();

          foreach (SearchResult sr in allResults)
          {
               Response.Write(sr.Properties["name"].ToString());
          }
     }

您可以使用
PrincipalSearcher
和“示例查询”主体进行搜索:

// 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-请阅读MSDN文章,这篇文章很好地展示了如何最好地利用
System.DirectoryServices.AccountManagement
中的新功能。或者查看名称空间

当然,根据您的需要,您可能希望在您创建的“示例查询”用户主体上指定其他属性:

  • DisplayName
    (通常为:名字+空格+姓氏)
  • SAM帐户名
    -您的Windows/AD帐户名
  • 用户主体名称
    -您的”username@yourcompany.com“样式名

您可以在
UserPrincipal
上指定任何属性,并将其用作
PrincipalSearcher

的“示例查询”。自我重新启动后,我再次测试了它,没有出现错误,然后添加了其余代码以显示在gridview中

 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();
 }

今天重新启动后,我再次测试了它,没有出现错误。我刚刚添加了search.propertiestoload(“any”);并添加了网格和绑定数据,效果非常好。谢谢马克
