20. IdP安装配置时，预上线环境测试显示登陆成功，但释放属性部分显示为空，这个一般是什么原因？

...

情况二：如果学校备份不可用，或者备份丢失，请重装IdP，IdP应用安装完成后，与CARSI联盟联系（邮件地址carsi@pku.edu.cn），走下线、上线流程并重新上传metadata。

22. IdP服务器使用CAS认证源，认证成功后，跳转到ds.carsi.edu.cn网页时报错 “opensaml::FatalProfileException at (https://xxx.xxx.edu.cn/Shibboleth.sso/SAML2/POST)”

具体错误信息：

opensaml::FatalProfileException

The system encountered an error at Fri Jul 15 11:17:24 2022

To report this problem, please contact the site administrator at root@localhost.

Please include the following message in any email:

opensaml::FatalProfileException at (https://xxx.xxx.edu.cn/Shibboleth.sso/SAML2/POST)

SAML response reported an IdP error.

Error from identity provider:

Status: urn:oasis:names:tc:SAML:2.0:status:Requester
Sub-Status: urn:oasis:names:tc:SAML:2.0:status:AuthnFailed
Message: An error occurred.

问题分析：

1. 查看idp-process.log， 检查是否有以下错误：
   2022-07-15 11:31:29,165 - 192.168.xx.xxx - ERROR [org.jasig.cas.client.util.CommonUtils:439] - SSL error getting response from host: cas-pass.XXXX.edu.cn : Error Message: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty

   at org.jasig.cas.client.util.CommonUtils.getResponseFromServer(CommonUtils.java:440)
   

2. 如果有以上错误，请检查CAS认证服务网站数字证书，通常因其证书不完善导致报错。

解决办法：

请学校认证服务器更新完善数字证书。
