ASP.net Identity 2.0 Sign-out another user

Question

I\'m using asp.net MVC and ASP.net Identity 2.0.

On my website Admin has option to ban user, and I would like when user is banned that he is automatically signed-out

You'll need to configure cookie invalidation in Auth.Config.cs:

public void ConfigureAuth(IAppBuilder app)
{
    // important to register UserManager creation delegate. Won't work without it
    app.CreatePerOwinContext(UserManager.Create);

    app.UseCookieAuthentication(new CookieAuthenticationOptions
    {
        Provider = new CookieAuthenticationProvider
        {
            OnValidateIdentity = SecurityStampValidator
                .OnValidateIdentity(
                    validateInterval: TimeSpan.FromMinutes(10),
                    regenerateIdentityCallback: (manager, user) => user.GenerateUserIdentityAsync(manager))
        },
        // other configurations
    });

    // other stuff
}

and then update security stamp as Hao Kung says when users are banned.

I've blogged about this recently
