MIT的kerberos、window的AD与Aapche Directory均提供了Kerberos服务器，但是这三者均是面向PC而不是应用的，所以配置与初始化相对来说比较复杂。所以，在这里自己用java实现了一个kerberos服务端与客户端，包含kerberos所有的基本功能。默认的加密方式为AES，默认的序列化方式为kryo，账户密码默认通过文件进行保存。

1. 创建服务端账户密码，通过ks-tool中的FileDatabaseProcessor创建（main函数中已注释掉部分）。或者根据命令行来进行创建。创建结果为ks-example中的ks-database.dat
2. 创建客户端账户密码，通过ks-tool中的FileClientDatabaseProcessor创建。创建结果为ks-example中的ks-client-database.dat

	a = new TicketGrantTicketServer(8906);
	a.setTgtHandlerBuilder(baseTGTHandlerBuilder);
	new Thread(a).start();

	// BaseTGSHandlerBuilder baseTGSHandlerBuilder=new
	// BaseTGSHandlerBuilder();
	s = new TicketGrantServer(8907);

	new Thread(s).start();

  servlet listener方式启动,通过配置web.xml实现
```xml
   	<context-param>
		<param-name>tgtServerPort</param-name>
		<param-value>8906</param-value>
	</context-param>
	<context-param>
		<param-name>tgsServerPort</param-name>
		<param-value>8907</param-value>
	</context-param>
	<context-param>
		<param-name>fileDatabase</param-name>
		<param-value>E:/ks-database.dat</param-value>
	</context-param>
	<listener>
		<listener-class>com.cgs.kerberos.server.KerberosServletContextListener</listener-class>
	</listener>

	//创建服务请求的内容（自动获取tgt,st）,如在电脑pc1上
	byte[] request = kerberosFacade.getThirdRequestByte("server");
	
	//你请求的服务端验证，并创建回送的信息()，如在电脑pc2上
	byte[] response = kerberosFacade.checkServiceTicket(request);
	
	//验证是否是你请求的服务回送的信息，如在电脑pc1上
	boolean ok = kerberosFacade.checkServiceResponse(response, "server");
