开始run EMC的DFS的一个例子TQueryServiceTest， 发现老是报Authorization failed的错误

	private String repository =  "test";
	
	/* The username to login to the repository */
	private String userName =  "username";
	
	/* The password for the username */
	private String password =  "passowrd";
	
	/* The address where the DFS services are located */	
	private String host = "http://IP:port/services";

以上的配置信息如果在DFC使用的时候是正常的， 可是到DFS这边就出错。

解决方法：

这里的 username 必须和 Documentum\config\dfc.properties 配置的dfc.globalregistry.username 完全一致
