Google Authenticator servlet

So I am finally getting around to building a google authenticator deploy-able appliance however I almost fee like this has already been done, just have not found it.

I went back and followed my last post and build a new server, and added in tomcat.

Im able to deploy war files and a single servelet that will execute the the google authenticator and retrieve the information required, however the switching of the user is where im stuck.

While im actually running a command on the server to execute the code, its running as the tomcat service , i need to be able to change the user to run the command in the context of the user.

here is the current code for the servlet:
package com.srk.pkg;
import javax.servlet.*;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.*;
import com.oreilly.servlet.ServletUtils;
// Helpful code

First remove your drives from the ready nas 1 by 1, and mark on each one the number it is starting from left to right ( 1,2,3,4)
Now place them in a PC and this is probably important , put them on each sata port in order, in my case my ports are 0,1,2,3.
