Environnement:Outlook Add-In ne parvient pas à Authentifier contre ADFS serveur
- Perspectives 2016
- Windows Server 2016
- Microsoft Visual Studio Communauté 2017
Description du problème:
Je travaille sur un complément Outlook supposé s'authentifier sur un serveur ADFS.
Après avoir soigneusement suivant les étapes décrites ici: https://tech.greenhouse.io/2016/08/01/create-adfs-instance-on-azure-virtual-machine.html
Je suis en mesure de se connecter via ADFS avec succès dans Internet Explorer et Chrome à l'extérieur que les utilisateurs ADFS.
Cependant lorsque vous essayez d'utiliser la même approche pour se connecter via le complément Outlook je reçois la page qui dit ce qui suit:
ADFS Login An error occurred An error occurred. Contact your administrator for more information. Error details © 2016 Microsoft
Voici les exemples de fichiers journaux.

Voici l'exemple de code sur le complément:
// 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;
...
qui jette l'exception quand il attend un document XML à partir du serveur:
Exception: System.NullReferenceException: Object reference not set to an instance of an object.

Question: Quelles mesures devrais-je prendre pour résoudre ce problème?
Merci d'avance.
