そのため、認証でうまく機能することを確認するためにテストしているコードがいくつかあります。ストレート kerberos に対しては問題なく動作するため、AD ではわずかな問題が発生するだけであると考えました。残念ながら、KrbException: KDC has no support for encryption type (14) を回避できません。
エラーが暗号化タイプの不一致であることはわかっています。問題が発生したのはコードだけです。私は何も設定していないので、kinit と同じデフォルトを継承する必要があると思いますが、明らかにそうではありません。
コード-
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();
および jaas.conf
Server {
com.sun.security.auth.module.Krb5LoginModule required
useKeyTab=false
storeKey=true
useTicketCache=true
principal="accumulo@test.SQRRL.COM";
};
そして、スタックトレース-
