Apologies if my questions were addressed at the meeting in early June, but post upgrade to Ubuntu 14.04 (Tahr) I have been having minimal luck at navigating the UCT NTLM barriers. As far as I can see, everything in my cntlm.conf is configured as it was before (on Narwhal!), and I have been through your guide from top to bottom to try and address the issue. I am by no means a linux expert but my browser settings, network settings and .bashrc all seem to be properly set-up. ICTS ensure me that no changes to the proxy have been made, but a number of us down in Oceanography (heavy linux & OSx Macports users) are having issues.
wget tests for google.com authenticate through the proxy properly, but, for example wget for www.nasa.gov returns the following:
502 Proxy Error (Forefront TMG denied the specified url).
Happy to provide more info if it helps. Any hints? Any awareness about changes that have been made to NTLM recently? No luck with Firefox either. I had a go at setting up tinyproxy, following the instructions, but I am not sure if I configured it properly.
