登陆域，在网上很多

详细解释下search方法

第一个参数：

String

域名入口，比如说你要登陆查询的域是：test.com，那查询节点是 “DC=test,DC=com”

第二个参数：

String

过滤器，筛选，列几个简单的

更多的看这里http://www.cnblogs.com/dreamer-fish/p/5832735.html 侵删

第三个参数：

SearchControls

要查询的字段，用法

new SearchControls().setReturningAttributes(要查询的字段，给null是返回所有查询到的字段);

下面例子是查询指定的组织单位的小栗子
