本文介绍了使用Active Directory时DirectoryServicesCOMException(0x80072020)从ASP.NET应用程序的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我保持了传统的ASP.NET 3.5应用程序,查询Ac​​tive Directory。该应用程序使用集成Windows身份验证,旨在利用其自身的安全上下文,而不是一个专用的用户名和密码才能连接到Active Directory。

I'm maintaining a legacy ASP.NET 3.5 application that queries Active Directory. The application uses "Integrated Windows Authentication" and is designed to connect to Active Directory using its own security context rather than a dedicated username and password.

下面是相关code。

using (DirectoryEntry root = new DirectoryEntry())
using (DirectorySearcher searcher = new DirectorySearcher(root))
{
    searcher.Filter = string.Format("(&(samAccountName={0})(objectClass=user)(objectCategory=person))", userName.Trim());
    SearchResultCollection results = searcher.FindAll();
}

尽管它使用ASP.NET 3.5,它需要从ASP.NET 4.0应用程序池可运行的,由于现有的基础设施的制约。

Although it uses ASP.NET 3.5, it needs to be runnable from an ASP.NET 4.0 application pool due to existing infrastructure constraints.

在调用的FindAll 抛出在某些情况下出现以下异常:

The call to FindAll throws the following exception under certain circumstances:

System.DirectoryServices.DirectoryServicesCOMException(0x80072020):发生操作错误

当我检查与Visual Studio调试器异常对象时, ExtendedErrorMessage 属性包含的更多详细信息:

When I inspect the exception object with the Visual Studio debugger, the ExtendedErrorMessage property contains more detailed information:

000004DC:LdapErr:DSID-0C0906E8,注释:为了执行此操作成功绑定必须在连接上完成,数据0,v1db1

下面的截图显示了这个看起来像在Visual Studio中的调试器:

The following screenshot shows what this looks like in Visual Studio's debugger:

我发现了一些变通办法,使这项工作,但他们都不是可以接受的对我说:

I've found some work-arounds to make this work, but none of them are acceptable to me:

  1. 禁用的集成Windows身份验证的,而是使用的基本身份验证
  2. 在IIS,ASP.NET 2.0下运行的应用程序利用的网络服务的帐户和ASP.NET模拟的禁用
  3. 只从Web服务器访问应用程序,使用的本地主机的作为主机名。
  4. 使用ASP.NET模拟在web.config中一个硬codeD帐户。
  1. Disabling Integrated Windows Authentication and instead using Basic Authentication.
  2. In IIS, running the application under ASP.NET 2.0 with the Network Service account and ASP.NET impersonation disabled.
  3. Only accessing the application from the web server, using localhost as the host name.
  4. Using ASP.NET impersonation with a hard-coded account in web.config.

我从网上查到了一些建议,但它们都没有彻底解决了这个问题:

What Doesn't Work

I've found some suggestions from the Internet, but none of them completely resolved the problem:

  1. 使用 HostingEnvironment.Impersonate()
  2. 禁用模拟。

我想使这项工作,而无需重新配置在Active Directory中任何东西。它的工作原理在一定的IIS配置细如上图所示,所以我相信这应该有可能使通过重新配置应用程序或IIS(除了改变.NET framework版本)的工作。

What I Want

I would like to make this work without having to reconfigure anything in Active Directory. It works fine under certain IIS configuration as shown above, so I believe it should be possible to make it work by reconfiguring the application or IIS (except for changing the .NET framework version).

推荐答案

我相信这个问题有多种原因:

I believe the problem had multiple causes:

  1. 使用ASP.NET模拟的。
  2. 在一个ASP.NET 4.0应用程序池运行ASP.NET 3.5应用程序。

要解决的第二个,应用程序升级到ASP.NET 4.0和IIS配置为使用ASP.NET 2.0。

To resolve the second one, upgrade the application to ASP.NET 4.0 or configure IIS to use ASP.NET 2.0.
