Question

使用这个例子，几乎让我的连接工作

http://blogs.nologin.es/rickyepoderi/index.php?/archives/105-Oracle-Driver-and-Kerberos.html

但启用kerberos缓存并调试后，正确获取我的主体名称并且凭据成功，则会出现与故障单相关的错误。

使用okinit（来自oracle 12的oracle kinit）生成票证

我正在使用java 7，但使用另一个没有问题。有没有办法用jvm正确读取票证（请参阅jdk的kinit也不要创建正确的票证）

Answer 1

我正在分享这段代码，这段代码一直在为我工作。您是否设置了kerberos缓存文件的位置？

OracleDriver driver = new OracleDriver();
Properties prop = new Properties();

prop.setProperty(OracleConnection.CONNECTION_PROPERTY_THIN_NET_AUTHENTICATION_SERVICES,
  "("+AnoServices.AUTHENTICATION_KERBEROS5+")");  
prop.setProperty(OracleConnection.CONNECTION_PROPERTY_THIN_NET_AUTHENTICATION_KRB5_MUTUAL,
  "true");    

/* If you get the following error [Unable to obtain Principal Name for 
 * authentication] although you know that you have the right TGT in your
 * credential cache, then it's probably because the JVM can't locate your
 * cache.
 * For example, here my credential cache is
 *        C:\Documents and Settings\Jean de Lavarene\krb5cc
 * because when I run klist I get the following:
 *   > ./klist
 *   Ticket cache: FILE:C:\Documents and Settings\Jean de Lavarene\krb5cc
 *   Default principal: client@US.ORACLE.COM
 *
 *   Valid starting     Expires            Service principal
 *   06/21/16 13:23:02  06/21/16 23:23:02  krbtgt/US.ORACLE.COM@US.ORACLE.COM
 *   renew until 06/21/16 13:23:02
 * This isn't the default location, so I need to provide the location. Note
 * that the default location on windows is "C:\Documents and Settings\krb5cc_username".
 */
prop.setProperty(OracleConnection.CONNECTION_PROPERTY_THIN_NET_AUTHENTICATION_KRB5_CC_NAME,
  "C:\\Documents and Settings\\Jean de Lavarene\\krb5cc");
Connection conn  = driver.connect(url,prop);
String auth = ((OracleConnection)conn).getAuthenticationAdaptorName();
System.out.println("Authentication adaptor="+auth);
