AuthenticationServiceException：验证SAML消息时出错

Question

我在我的应用程序中使用Spring saml身份验证进行SSO。但每次SAML登录都失败了。相同的配置在另一台机器上正常工作。我遇到异常：

org.springframework.security.authentication.AuthenticationServiceException: Error validating SAML message
    at org.springframework.security.saml.SAMLAuthenticationProvider.authenticate(SAMLAuthenticationProvider.java:95)
    at org.springframework.security.authentication.ProviderManager.authenticate(ProviderManager.java:156)

    at org.springframework.security.web.context.SecurityContextPersistenceFilter.doFilter(SecurityContextPersistenceFilter.java:87)
...

有什么想法吗？
