DomainContect正在引发“登录失败：未知用户名或密码错误”。

Question

我在asp.net mvc Web应用程序中有以下代码来检索Active目录用户名： -

public List<DomainContext> GetADUsers(string term=null)
{
    List<DomainContext> results = new List<DomainContext>();

    using (var context = new PrincipalContext(ContextType.Domain, "v800047"))
    using (var searcher = new PrincipalSearcher(new UserPrincipal(context)))
    {

以上在我们的开发环境中运行良好，但是当我将代码移动到登台服务器并且我相应地更改了AdServerName时，我收到以下错误： -
