OpenAM - 将会话属性添加到 OpenID Connect 声明中

Question

我正在使用配置为具有 SAML 信任圈的 OpenAM 13.5，以便将登录到我们的应用程序与第三方 IdP 联合起来。第三方收到的一些 SAML 断言被映射为会话级属性。 SAML 部分工作正常，但我需要连接到 OpenAM 一个可以与 OpenID Connect 通话的应用程序。我创建了一个 OpenID Connect 服务，相应地配置了客户端，我可以使用流程“App -> OpenAM UI -> 3rd party IDP -> OpenAM OIDC -> App”成功登录。

问题是我只能检索映射到数据存储的属性 - 映射的声明中不包含会话属性（例如 AuthLevel、IDP 名称等）。

我尝试编辑 OIDC 声明默认脚本，该脚本有一个似乎包含我需要的会话变​​量，但不幸的是会话变量始终为空。

这是正确的方法吗？为什么会话为空？我需要启用什么才能阅读它吗？

提前感谢您的帮助。

Answer 1

您无法在 OIDC 声明脚本中检索 SSO 会话属性，因为 OAuth2 客户端未在令牌请求中发送 SSO 跟踪 cookie。

只有在您使用 AM 专有功能“始终在 ID 令牌中包含声明”时才有可能。

Answer 2

正如 Bernhard 在 cmets 中所描述的，一旦请求到达 /userinfo 端点，OpenAM 就无法将访问令牌与活动会话协调起来（并且会话也不再存在）。

但是，当通过激活专有 AM 功能“始终在 ID 令牌中包含声明”访问 ID 令牌中的声明时，会话对象可用，我们可以轮询其属性！

对于未来的读者，这是我修改 OIDC 脚本的方式：
