WSO2 身份服务器在与 ADFS 服务器集成时抛出 Nullpointerexception
WSO2 Identity Server throwing Nullpointerexception while integrating with ADFS Server
我正在使用 WSO2 Identity Server 5.10.0，我正在尝试使用外部 ADFS 服务器实施 WSO2IS。
我已经按照 https://docs.wso2.com/display/IS570/Configuring+AD+FS+as+a+Federated+Authenticator 示例从 WSO2 管理控制台将我的 ADFS 配置为身份提供者。
服务器能够重定向到 ADFS 登录页面，但是当 ADFS 向 WSO2IS 发送回调时，它会抛出 NullPointerException。
完整的Stack trace如下：

WSO 中设置的 ADFS 详细信息：
Identity Provider Name: adfs
Uploaded valid PEM certificate
Federation Authenticators -> SAML2 Web SSO Configuration -> Enabled SAML2 Web SSO
Service Provider Entity Id : wso2is
Identity Provider Entity Id : {from ADFS metadata}
ACS URL : https:\{ip}:9443\commonauth
SSO URL : {from ADFS metadata}
谁能告诉我是否有问题？
已报告此空指针问题 here and fixed in the master. But this NPE issue thrown from this line of code when there is a failure happened when there is a failure happens when processing the SAML response coming from federated IDP and the user is null. You can find that actual error in the SAML outbound component from here。
所以您的根本问题似乎是用户标识符在从 ADFS 端接收到的 SAML 断言中不可用。请检查一下。请验证从 ADFS 获取的 saml 响应，并检查它是否在身份验证响应中发送用户信息。
