android sdk并没有提供ldap 的接口，看到网上有封装好的jar包。
ldap sdk下载地址：https://www.unboundid.com/products/ldap-sdk/files/unboundid-ldapsdk-2.3.4-se.zip
将unboundid-ldapsdk-se.jar引用到项目中。

注意事项：
1、若包引用无效，在“Order and Export”中将jar文件勾上，clean一下。
2、在manifest中添加<uses-permission android:name="android.permission.INTERNET" />权限。
