System.DirectoryServices.DirectoryServicesCOMException:发生操作错误。

Question

我正在尝试从在本地intranet上提交ASP.NET表单的用户那里获取电子邮件地址。在我的本地机器上测试时，它工作得很好。但当我发布并开始在生产环境中测试它时，它不像第74行。

这段代码在我的页面加载中只是为了测试目的，所以在中可以获得一个即时的result....but，它永远不会在生产环境中加载页面，但在本地机器上调试VS时工作得很好……

IIdentity id = WindowsIdentity.GetCurrent();
        WindowsIdentity winId = id as WindowsIdentity;

        if (id == null) 
        {
            txtDetailedProblem.Text = "Identity is not a windows identity";
            return;
        }

        string userInQuestion = winId.Name.Split('\\')[1];
        string myDomain = winId.Name.Split('\\')[0]; // this is the domain that the user is in
        // the account that this program runs in should be authenticated in there                    
        DirectoryEntry entry = new DirectoryEntry("LDAP://" + myDomain);
        DirectorySearcher adSearcher = new DirectorySearcher(entry);

        adSearcher.SearchScope = SearchScope.Subtree;
        adSearcher.Filter = "(&(objectClass=user)(samaccountname=" + userInQuestion + "))";
        SearchResult userObject = adSearcher.FindOne();
        if (userObject != null) 
        {
            string[] props = new string[] {"mail"};
            foreach (string prop in props) 
            {
                txtTEST.Text = prop.ToString() + " " + userObject.Properties[prop][0].ToString();
            }
        }

IIdentity id = WindowsIdentity.GetCurrent();
            WindowsIdentity winId = id as WindowsIdentity;

            if (id == null)
            {
                CurrentUserEmail = "identity is not a windows identity";
                return;
            }

            var name = winId.Name;

            string userInQuestion = name.Split('\\')[1];
            string myDomain = name.Split('\\')[0]; // this is the domain that the user is in
            // the account that this program runs in should be authenticated in there                    

            using (HostingEnvironment.Impersonate())
            {
                DirectoryEntry entry = new DirectoryEntry("LDAP://" + myDomain);
                DirectorySearcher adSearcher = new DirectorySearcher(entry);

                adSearcher.SearchScope = SearchScope.Subtree;
                adSearcher.Filter = "(&(objectClass=user)(samaccountname=" + userInQuestion + "))";
                SearchResult userObject = adSearcher.FindOne();
                if (userObject != null)
                {
                    string[] props = new string[] {"mail"};
                    foreach (string prop in props)
                    {   //when it works set variable to CurrentUserEmail instead of txtDetailPrblem textbox
                        CurrentUserEmail = userObject.Properties[prop][0].ToString();
                    }
                }

            }
