Any help is greatly appreciated.  We have DNN 4.9 running as out intranet.  On a different server, we have a web-based time tracking application for employees to keep their time in.  It is written in Python, and there is a Single Sign-On interface I'm trying to get working.

The python script basically takes a username, and sends it as an HTTP header to the server, then sends the user a cookie.

Since my DNN users are already logged in by the time they would use this site, I'm trying to figure out a way to dynamically grab the DNN username, and send it as an HTTP header in an ASP.net script or something.

Is there a tool that will do this, or do I have to do it manually?  I'm not very good at scripting, any help is greatly appreciated!

The python script that works (with the username hard coded) is below:

[code]
#!/usr/bin/env python
# -*- coding: utf-8; mode: python; py-indent-offset: 4; indent-tabs-mode: nil -*-
# vim: fileencoding=utf-8 tabstop=4 expandtab shiftwidth=4
