所以我有一些我正在测试的代码,以确保它可以很好地用于身份验证。它对直接 kerberos 效果很好,所以我认为 AD 应该只有一些小问题。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。但是我可以很好地启动,它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。
编码-
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";
};
而且,堆栈跟踪-
