Our IT department decided to install Windows ISA server to proxy all of  
our  
internet traffic. This server requires that any client authenticate via  
Kerberos or NTLM. That works fine for IE or Firefox but it broke all my  
ruby  
scripts that fetch various things from the internet for me.

Is anyone aware of code that allows open-uri or Net::HTTP to  
authenticate  
with a proxy server that only supports NTLM/Kerberos? I don’t  
necessarily  
need an NTLM implementation in ruby - just a way forward to get the  
right  
headeres into the web requests at the right time. Heck, if any Windows  
gurus  
know the correct API calls to make to get the tokens out that I need  
that  
will work too.

I have googled (and yahooed, and even ‘ask’-ed) but to no avail. I found  
a  
proxy server written in python ([http://ntlmaps.sourceforge.net/](http://ntlmaps.sourceforge.net/)) which  
will  
work if I ask ruby to proxy through it, but otherwise I haven’t found  
any  
workable solutions.

Thanks in advance for any help!

p.s. I’m not real up on the terminology but NTLM seems distinct from  
Kerberos - please forgive any mistakes above because of my  
misunderstanding.
