c# - UserPrincipal 对象，Active Directory 查询 : DirectoryServicesCOMException

Question

为重复 System.DirectoryServices.DirectoryServicesCOMException: An operations error occurred 道歉但我还不能发表评论，也没有答案。

这个问题的解决方案没有用。 Error on publishing: System.DirectoryServices.DirectoryServicesCOMException

我在 Visual Studio 2010 中有一个带有 Razor View 引擎的新 ASP.NET MVC 3 Web 应用程序项目。它是通过添加两行代码添加到主 Controller 和 System.DirectoryServices.AccountManagement 生成的。引用已添加到项目中。

这在我的本地 PC 上运行良好，但在我创建的 Windows 2008 R2 IIS 7.5 站点上出现错误。

该网站使用 defaultAppPool ，它正在使用 ApplicationPoolIdentity .已授予根站点文件夹 IUSR和 IIS AppPool\DefaultAppPool读取权限。

Controller 中的两行代码是:

PrincipalContext context = new PrincipalContext(ContextType.Domain);
ViewBag.name = UserPrincipal.FindByIdentity(context, User.Identity.Name).DisplayName;

我得到的错误是:

System.DirectoryServices.DirectoryServicesCOMException: An operations error occurred.

别客气，这是我的第一个问题!

这很可能是权限问题。检查运行应用程序池的帐户是否有权执行这些 Active Directory 调用。如果是本地计算机帐户，则可能不会。
