我正在尝试使用 Active Directory 凭据执行 Spring Security Kerberos，如http://docs.spring.io/spring-security-kerberos/docs/1.0.1.RELEASE/reference/htmlsingle/#samples-sec-中所述服务器-win-auth。我想说我已经完成了大部分内容（SPN、keytabs 等）。现在我的校验和失败了。假设我更改了我的主体名称，我会收到一个 AES 加密错误。
我在 RHEL 6 上使用 Spring Boot 和来自https://github.com/spring-projects/spring-security-kerberos/tree/master/spring-security-kerberos-samples/sec-server的 Oracle Java 1.8 + JCE 示例-win-auth
这是我在运行 jar 时得到的
Debug 为 true storeKey true useTicketCache false useKeyTab true doNotPrompt true ticketCache 为 null isInitiator false KeyTab 为 /home/boss/webdev125-3.keytab refreshKrb5Config 为 false principal 为 http/webdev@EXAMPLE.ORG tryFirstPass 为 false useFirstPass 为 false storePass 为 false clearPass是假的
主体为 http/webdev@EXAMPLE.ORG 将使用 keytab 提交成功

其他一些细节：
- /etc/krb5.conf 确实有 default_tgs_enctypes，default_tkt_enctypes 包括 aes256-cts-hmac-sha1-96
- 默认 keytab 位置在应用程序和 krb5.conf 之间匹配
- 在 Windows 服务器上生成密钥表，然后复制到 RHEL
