Android and auto-proxy support

Hi,

our organization allows internet access only through proxy servers and we have WPAD working as automatic proxy detection in our organization and it works fine for PC/MAC/iPhone however Android does not have any option to enable auto-proxy support or user authentication. I’m sure we are not the only organization facing this issue, can someone help or suggest what app can be used to enable auto-proxy with authentication on Android when they connect to organisation’s wireless network?
