java - 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-server-win-auth 中所述.我想说我已经记下了大部分内容(SPN、 key 表等)。现在我有一个校验和失败。假设我更改了主体名称，我收到 AES 加密错误。

我在 RHEL 6 上使用 Spring Boot 和 Oracle Java 1.8 + JCE样本来自 https://github.com/spring-projects/spring-security-kerberos/tree/master/spring-security-kerberos-samples/sec-server-win-auth

这是我运行 jar 时得到的结果

一些其他细节:

• /etc/krb5.conf 确实有 default_tgs_enctypes、default_tkt_enctypes 以包含 aes256-cts-hmac-sha1-96
• 默认 key 表位置在应用程序和 krb5.conf 之间匹配
• key 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。一旦我清理了它，错误就停止了。此链接帮助我找到了解决方案 - https://developer.jboss.org/wiki/ConfiguringJBossNegotiationInAnAllWindowsDomain?_sscc=t
