accessing a page which request an openID authentication

[uni . mail . 2014]

I have a page that request an openID authentication "google ID" before you are 
able to download any file from it. 
this is the website "http://oc.gtisc.gatech.edu:8080/search.cgi?search=sality"; 
and I tried a lot but it dose not seem that the ordinary login using session or 
requests work on this case ? any guidance or help ?
