我想我知道问题是什么在这里 - 尽管我不知道如何解决它，这样的文件是为asp.net身份有时混乱（

I think I know what the problem is here - although I'm not sure how to fix it, such is the mess of documentation for asp.net identity sometimes ;(

我有完全一样的症状。问题的关键是，你用一个 SecurityStampValidator 验证并重新创建（如果需要的话）你的cookie？

I had exactly the same symptoms. The key issue is, do you use a SecurityStampValidator that verifies and recreates (if needed) your cookie?

我做的，而我被设定为非常频繁验证（从我Startup.auth）：

I do, and mine is set to validate very frequently (from my Startup.auth):

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, User, int>(
        validateInterval: TimeSpan.FromMinutes(1), 
        regenerateIdentityCallback: (manager, user) =>
        {
            return user.GenerateUserIdentityAsync(manager);
        },
        getUserIdCallback: id => (int.Parse(id.GetUserId()))
        ),
},

所以假设你有类似code - 你怎么重建。简单 - 登录，打在你的应用程序页面，然后等待定义validateInterval失效 - 所以对我来说，等待1 minue。 1分钟后，注销。的景气的。我不会退出。

现在，这里的问题是，GenerateUserIdentiyAsync方法再现您的身份验证cookie，则signout发生之后。我已经验证了与记录 - 在 _authenticationManager.SignOut（DefaultAuthenticationTypes.ApplicationCookie）; 在我注销等动作发生，然后Cookie会再生。卫生署。

Now, the issue here is that the GenerateUserIdentiyAsync method RECREATES your auth cookie, right after the signout has happened. I've verified that with logging - the _authenticationManager.SignOut(DefaultAuthenticationTypes.ApplicationCookie); in my LogOff action is happening, and then the cookie gets regenerated. Doh.

如何修复 - 好明显的事情是增加validateInterval，但影响安全 - 如果有人登录到2台电脑，并更改其密码，我想这两个帐户被注销pretty快速 - 这是这是什么一样

How to fix - well the obvious thing is to increase the validateInterval, but that impacts security - If someone is logged on to 2 computers, and changes their password, I'd like both accounts to be logged out pretty swiftly - which is what this does.

所以，这是（可能）的原因。对不起，我不能提供一个很好的修复：（

So, that's (probably) the cause. Sorry I can't offer a nice fix :(
