使用sustainsys我正在尝试设置SAML身份验证以及通过应用程序形式进行标准用户名/密码身份验证的后门。
我可以通过 SAML 登录和注销，没有任何问题。
我可以通过应用程序内的表单登录，但是在注销时，虽然它确实成功注销了，但我得到了一个异常：

注销控制器如下所示：
public ActionResult LogOff()
{
AuthenticationManager.SignOut();
return RedirectToAction("Login", "Account");
}
中间件的设置如下：
app.CreatePerOwinContext(SystemContext.Create);
app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
app.CreatePerOwinContext<ApplicationSignInManager>(ApplicationSignInManager.Create);
app.UseCors(Microsoft.Owin.Cors.CorsOptions.AllowAll);
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
LoginPath = new PathString("/account/samllogin"),
Provider = new CookieAuthenticationProvider
{
OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, User>(
validateInterval: TimeSpan.FromDays(30),
regenerateIdentity: (manager, user) => user.GenerateUserIdentityAsync(manager))
}
});
app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
app.UseSaml2Authentication(new Saml2AuthenticationOptions(true));
我正在使用同一个控制器来注销 SAML 身份验证用户以及标准应用内用户名/密码身份验证用户。
对于 SAML 用户，注销工作没有问题。
当注销非 SAML 用户时，它会通过所有中间件，成功执行控制器，从而成功注销，但在此之后，它会抛出此异常。
我在调试此问题时遇到了一些困难，但我相信问题可能发生在Sustainsys.Saml2.WebSSO.LogOutCommand.InitiateLogout诸如SessionIndex查找声明之类的地方，但由于用户未使用 SAML 进行身份验证，因此当然不存在。
如果用户未通过 SAML 身份验证，我猜测身份验证处理程序甚至不应该命中此代码块。
我是否缺少一些配置来启用非 SAML 用户和 SAML 用户？
这里的例外真的很奇怪，所以我可能会因此而大失所望。
