具有Azure Active Directory身份验证票证寿命的Microsoft.Owin.Security.OpenIdConnect

我正在构建一个多租户Web应用程序，该应用程序在此示例之后使用Microsoft.Owin.Security.OpenIdConnect，版本= 3.0.0.0和Azure Active Directory与Microsoft.IdentityModel.Clients.ActiveDirectory，版本= 2.19.0.0连接Office 365服务。

我们的Web应用程序客户端（用户代理）使用asp.NET cookie验证到我们的服务器，而我们的服务器和授权服务器（此处为Azure AD）之间的验证是使用OpenID授权代码流进行的。

我们为Asp.NET Cookie设置了30天的滑动到期期限。但是，即使将UseTokenLifetime = true设置为True（这应该与两种身份验证机制的生存期匹配），我们仍然无法从Authority Server获得AuthenticationTicket 。

我们面临的问题是：我们的最终用户必须频繁地重新登录（少于一小时）。然后的问题是，我们如何在这种owin openidconnect中间件中增加/更改身份验证票证的寿命？

备注：我还发布了有关ADAL使用刷新令牌的问题。据我们了解，该问题仅与身份验证有关。由ActiveDirectory客户端管理的授权问题access_token和refresh_token的生存期与此问题无关。如果我错了，请纠正我。
