针对Active Directory的Java身份验证,身份验证不匹配？

Question

所以我有一些代码,我正在测试,以确保它可以很好地进行身份验证.它可以很好地对抗直接的kerberos,所以我认为应该只有一些与AD的轻微打嗝.不幸的是,我无法解决KrbException:KDC不支持加密类型(14).

我知道错误是加密类型不匹配.但我可以开得很好,这只是在我遇到问题的代码中.我没有设置任何东西,所以我认为它应该继承与kinit相同的默认值,但显然情况并非如此.

代码-

System.setProperty("sun.security.krb5.debug", "true");
System.setProperty("java.security.krb5.realm", "TEST.SQRRL.COM");
System.setProperty("java.security.krb5.kdc", "172.16.101.128");
System.setProperty("java.security.auth.login.config", "./conf/jaas.conf");
System.setProperty("javax.security.auth.useSubjectCredsOnly", "true");

// "Client" references the JAAS configuration in the jaas.conf file.
LoginContext loginCtx = null;
loginCtx = new LoginContext("Server", new LoginCallbackHandler("test".toCharArray()));
loginCtx.login();
subject = loginCtx.getSubject();

和jaas.conf

Server {
com.sun.security.auth.module.Krb5LoginModule required
useKeyTab=false
storeKey=true
useTicketCache=true
principal="accumulo@test.SQRRL.COM";
};

并且,堆栈跟踪 -

Answer 1

所以,我已经超越了这个阶段.我只能猜测Windows Server 2012的活动目录中的DES支持被破坏了,因为我最终调整了我的krb5.conf文件,并将两个默认的票证类型和允许的类型设置为aes256-cts-hmac-sha1-96和它适用于一个用户.在AD中为其他用户启用aes256后,它继续工作.
