環境にADFSサーバーに対して認証に失敗します:Outlookアドインは
私は、ADFSサーバーに対して認証するはずのOutlookアドインで作業しています。慎重に、ここで説明する手順に従った後

私はADFSユーザーとして、外部のInternet ExplorerとChromeの両方で正常にADFSを経由してログインすることができています。アドインの見通しを経由してログインすると同じアプローチを使用しようとすると

ここでは、アドインのサンプルコードです:
// String definitions
string samlAcs = Properties.Settings.Default.samlAcs;
string samlIdp = Properties.Settings.Default.samlIdp;
string serverUrl = Properties.Settings.Default.serverUrl;
string loginUrl = serverUrl + "/saml2/login/?idp=" + samlIdp;
var acsUrl = serverUrl + samlAcs;
string wiaHtmlBody = "";
HttpResponseMessage response;
try
{
response = await client.GetAsync(loginUrl);
...
try
{
response = await client.GetAsync(response.Headers.Location);
...
var wiaUrl = response.Headers.Location.ToString();
if (wiaUrl[0] == '/') wiaUrl = serverUrl + wiaUrl;
try
{
response = await client.GetAsync(wiaUrl);
response.EnsureSuccessStatusCode();
wiaHtmlBody = await response.Content.ReadAsStringAsync();
...
var wiaDoc = new XmlDocument();
try
{
wiaDoc.Load(new StringReader(wiaHtmlBody));
var samlNode = wiaDoc.DocumentElement.SelectSingleNode("//input[@name='SAMLResponse']");
string samlResponse = samlNode.Attributes["value"].Value;
...
それがサーバーからXMLドキュメントを期待したときに例外をスローどの:
Exception: System.NullReferenceException: Object reference not set to an instance of an object.
