如何为密钥斗篷身份提供者定义映射器？
How to define mappers for keycloak identity providers?
我在 Keycloak 中定义了一个连接到 PingFederate IDP 的身份提供者。
SAML 断言流程因 NullPointerException 而失败。具体错误在底部。
我调试了代码，怀疑是没有定义映射器有关。
我看到用户名是由一些奇怪的 ID 设置的，而不是由 saml 断言提供的 ID：identity.setUsername(subjectNameID.getValue())
我找不到关于定义 keycloak 身份提供商映射器的示例或教程。
有人可以帮忙吗？谢谢
