I had the same problem. After googling a little, I've discovered this is a known bug in Owin, because of the way they handle cookies.

This issue was submitted to Katana Team, but it looks they won't fix it at all. There are many workarounds for this, but this was the simplest I could find:

    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public ActionResult ExternalLogin(string provider, string returnUrl)
    {
        ControllerContext.HttpContext.Session.RemoveAll();

        // Request a redirect to the external login provider
        return new ChallengeResult(provider, Url.Action("ExternalLoginCallback", "Account", new { ReturnUrl = returnUrl }));
    }

See this question for more details about this bug, and let me know if this works well for you.
