+/**
+ * A KDC server.
+ * <p>
+ * Features:
+ * <ol>
+ * <li> Supports TCP and UDP
+ * <li> Supports AS-REQ and TGS-REQ
+ * <li> Principal db and other settings hard coded in application
+ * <li> Options, say, request preauth or not
+ * </ol>
+ * Side effects:
+ * <ol>
+ * <li> The Sun-internal class <code>sun.security.krb5.Config</code> is a
+ * singleton and initialized according to Kerberos settings (krb5.conf and
+ * java.security.krb5.* system properties). This means once it's initialized
+ * it will not automatically notice any changes to these settings (or file
+ * changes of krb5.conf). The KDC class normally does not touch these
+ * settings (except for the <code>writeKtab()</code> method). However, to make
+ * sure nothing ever goes wrong, if you want to make any changes to these
+ * settings after calling a KDC method, call <code>Config.refresh()</code> to
+ * make sure your changes are reflected in the <code>Config</code> object.
+ * </ol>
+ * Issues and TODOs:
+ * <ol>
+ * <li> Generates krb5.conf to be used on another machine, currently the kdc is
+ * always localhost
+ * <li> More options to KDC, say, error output, say, response nonce !=
+ * request nonce
+ * </ol>
+ * Note: This program uses internal krb5 classes (including reflection to
+ * access private fields and methods).
+ * <p>
+ * Usages:
+ * <p>
+ * 1. Init and start the KDC:
+ * <pre>
+ * KDC kdc = KDC.create("REALM.NAME", port, isDaemon);
+ * KDC kdc = KDC.create("REALM.NAME");
+ * </pre>
+ * Here, <code>port</code> is the UDP and TCP port number the KDC server
+ * listens on. If zero, a random port is chosen, which you can use getPort()
+ * later to retrieve the value.
+ * <p>
+ * If <code>isDaemon</code> is true, the KDC worker threads will be daemons.
+ * <p>
+ * The shortcut <code>KDC.create("REALM.NAME")</code> has port=0 and
+ * isDaemon=false, and is commonly used in an embedded KDC.
+ * <p>
+ * 2. Adding users:
+ * <pre>
+ * kdc.addPrincipal(String principal_name, char[] password);
+ * kdc.addPrincipalRandKey(String principal_name);
+ * </pre>
+ * A service principal's name should look like "host/f.q.d.n". The second form
+ * generates a random key. To expose this key, call <code>writeKtab()</code> to
+ * save the keys into a keytab file.
+ * <p>
+ * Note that you need to add the principal name krbtgt/REALM.NAME yourself.
+ * <p>
+ * Note that you can safely add a principal at any time after the KDC is
+ * started and before a user requests info on this principal.
+ * <p>
+ * 3. Other public methods:
+ * <ul>
+ * <li> <code>getPort</code>: Returns the port number the KDC uses
+ * <li> <code>getRealm</code>: Returns the realm name
+ * <li> <code>writeKtab</code>: Writes all principals' keys into a keytab file
+ * <li> <code>saveConfig</code>: Saves a krb5.conf file to access this KDC
+ * <li> <code>setOption</code>: Sets various options
+ * </ul>
+ * Read the javadoc for details. Lazy developer can use <code>OneKDC</code>
+ * directly.
