Spring Security Kerberos + AD，校验和失败

Question

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-服务器双赢身份验证。我想说我已经解决了大部分问题（SPN、keytabs 等）。现在我有一个校验和失败。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

这是我运行 jar 时得到的结果

Debug 为 true storeKey true useTicketCache false useKeyTab true doNotPrompt true ticketCache is null isInitiator false KeyTab is /home/boss/webdev125-3.keytab refreshKrb5Config is false principal is http/webdev@EXAMPLE.ORG tryFirstPass is false useFirstPass is false storePass is false clearPass是假的

主体是 http/webdev@EXAMPLE.ORG 将使用 keytab Commit Succeeded

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
• 默认密钥表位置在应用程序和 krb5.conf 之间匹配
• 密钥表在 Windows 服务器上生成，然后复制到 RHEL

我似乎与现有的服务主体映射有冲突。一旦我清理它，错误就停止发生。此链接帮助我找到了解决方案 - https://developer.jboss.org/wiki/ConfiguringJBossNegotiationInAnAllWindowsDomain?_sscc=t
