 Replying to [comment:18 deryni]:
 > The last patch that was submitted had issues that were requested to be
 fixed, the original author has not done that and no one else has stepped
 up to do it either.

 Issue 1: proxy servers don't like multiple Proxy-Authorization headers

 To fix this issue we must not send any Proxy-Authorization headers until
 recieve 407 Error from proxy.

 Issue 2: libpurple doesn't support using the current kerberos ticket to
 authenticate to the proxy server.

 patch was not about kerberos. I cant fix that.
 Just propose to use SSPI service on win platform to transparently
 authorizate user.
