针对 Active Directory 的 Java 身份验证，身份验证不匹配？

Question

所以我有一些代码正在测试，以确保它能很好地用于身份验证。它可以很好地对抗直接的 kerberos，所以我认为 AD 应该只会有一些小问题。不幸的是，我无法绕过 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 kinit 很好，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，我已经过了这个阶段。我只能猜测 Windows Server 2012 Activity 目录中的 DES 支持被破坏了，因为我最终调整了我的 krb5.conf 文件并将两个默认票证类型和允许的类型设置为仅 aes256-cts-hmac-sha1-96 和它适用于一个用户。在为AD中的其他用户启用aes256后，它继续工作。
