LDAP Authentication and Android

I'm trying to authenticate with a tomcat server through LDAP. Then after I'm authenticated send a basic GET request to get some data back (XML), and display it to the user. How would I go about authenticating with the server and then performing this request? A开发者_运维知识库re there any good good guides or libraries for this? I'm pretty new with this protocol..

You can find an example of client authentication at HttpClient Examples.
