NTLM Authentication for the HTTP Proxy seems to fail.

Logging (replace actual proxy hostname with proxy.example.com):

How to repeat:
Try to use a HTTP Proxy with NTLM authentication

Suggested fix:
Add NTLM authentication support.

Seems to be a privilege error

Even with the correct privileges it doesn't work.

Verified privileges with:
$ http_proxy='proxy.example.com:8080' https_proxy='proxy.example.com:8080' wget --proxy-user='DOMAIN\user' --proxy-password='secret' -O /dev/null http://oracle.com
