Answer 1

I have this error: AADSTS50020: User account .

If you don't update your website to be multi-tenant, upon other tenant users want to log on your website, it will prompt this same error.

I create a website with a multiple tenant but i have 400 error.

For the multi-tenant, you need to change your endpoint from your tenant (like https://login.microsoftonline.com/contoso.onmicrosoft.com ) to be common (like https://login.microsoftonline.com/common ). By this, the login request could be sent to an endpoint that multiplexes across all Azure AD tenants.

For the details, you could refer to here .

Thanks for your answer.

How I have to modify my code :

  public partial class Startup
{
    private static string clientId = ConfigurationManager.AppSettings["ida:ClientId"];
    private static string appKey = ConfigurationManager.AppSettings["ida:ClientSecret"];
    private static string aadInstance = ConfigurationManager.AppSettings["ida:AADInstance"];
    private static string tenantId = ConfigurationManager.AppSettings["ida:TenantId"];
    private static string postLogoutRedirectUri = ConfigurationManager.AppSettings["ida:PostLogoutRedirectUri"];

    public static readonly string Authority = aadInstance + tenantId;

    // This is the resource ID of the AAD Graph API.  We'll need this to request a token to call the Graph API.
    string graphResourceId = "https://graph.windows.net";

    public void ConfigureAuth(IAppBuilder app)
    {
        ApplicationDbContext db = new ApplicationDbContext();

        app.SetDefaultSignInAsAuthenticationType(CookieAuthenticationDefaults.AuthenticationType);

        app.UseCookieAuthentication(new CookieAuthenticationOptions());

        app.UseOpenIdConnectAuthentication(
            new OpenIdConnectAuthenticationOptions
            {
                ClientId = clientId,
                Authority = Authority,
                PostLogoutRedirectUri = postLogoutRedirectUri,

                Notifications = new OpenIdConnectAuthenticationNotifications()
                {

                   AuthorizationCodeReceived = (context) => 
                   {
                       var code = context.Code;
                       ClientCredential credential = new ClientCredential(clientId, appKey);
                       string signedInUserID = context.AuthenticationTicket.Identity.FindFirst(ClaimTypes.NameIdentifier).Value;
                       AuthenticationContext authContext = new AuthenticationContext(Authority, new ADALTokenCache(signedInUserID));
                       AuthenticationResult result = authContext.AcquireTokenByAuthorizationCode(
                       code, new Uri(HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Path)), credential, graphResourceId);

                       return Task.FromResult(0);
                   }
                }
            });
    }
}

Thanks
