各テナントが WsFed または OpenIdConnect(Azure) または Shibboleth(Kentor) の独自のメタデータ URl、ClientId、Authority などを定義できるマルチテナント アプリケーションがあります。すべてのテナントは DB テーブルに格納され、以下のように OwinStartup に登録されます。
// Configure the db context, user manager and signin manager to use a single instance per request
app.CreatePerOwinContext(ApplicationDbContext.Create);
app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
app.CreatePerOwinContext<ApplicationSignInManager>(ApplicationSignInManager.Create);
// Enable the application to use a cookie to store information for the signed in user
// and to use a cookie to temporarily store information about a user logging in with a third party login provider
// Configure the sign in cookie
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
// CookieName = "Kuder.SSO",
LoginPath = new PathString("/Account/Login-register"),
Provider = new CookieAuthenticationProvider
{
//Enables the application to validate the security stamp when the user logs in.
//This is a security feature which is used when you change a password or add an external login to your account.
OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, ApplicationUser>(
validateInterval: TimeSpan.FromMinutes(30),
regenerateIdentity: (manager, user) => user.GenerateUserIdentityAsync(manager))

Db で同じプロバイダー (ADFS、Azure、または Shibboleth) の複数の組織が有効になっていると、エラーが発生します。「app.Map」を拡張してみました。でも失敗しても。また、以下のコードを使用してすべてのプロバイダー (ADFS および Azure) をログアウトしますが、ログアウトも失敗します。
プロバイダーは、組織全体で使用する独自の認証タイプです。
HttpContext.GetOwinContext().Authentication.SignOut(provider, Microsoft.AspNet.Identity.DefaultAuthenticationTypes.ApplicationCookie, DefaultAuthenticationTypes.ExternalCookie);
ヘルプ/ガイダンスを探しています。注: 新しいテナントが追加されるたびに、appdomain を再利用しても問題ありません。複雑にするためにパイプラインを動的に再構築する必要はありません。
