Microsoft.Owin.Security。OpenIdConnect与Azure Active Directory身份验证票证生存期

我正在构建一个多租户web应用程序,该应用程序使用 Microsoft.Owin.Security。OpenIdConnect,版本=3.0.0.0 和Azure Active Directory Microsoft.IdentityModel.Clients。ActiveDirectory,版本=2.19.0.0 下列的 this sample .

我们的web应用程序客户端(用户代理)使用asp对服务器进行身份验证。NET cookie,而我们的服务器和授权服务器(此处为Azure AD)之间的身份验证是使用OpenID授权代码流进行的。

我们出发去Asp。NET cookie的有效期为30天。然而,即使在设置 UseTokenLifetime=真 这应该与两种认证机制的寿命相匹配。

我们面临的问题是:我们的最终用户必须频繁地重新加载(少于一小时)。问题是, 我们如何在这个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 a question 关于ADAL刷新令牌的使用。 根据我们的理解,这个问题只与身份验证有关。的生命周期 访问标记 和 刷新标记 这是由ActiveDirectory客户端管理的授权问题。如果我错了,请纠正我。
