Cached credentials
We have a proxy server that requires authentication (using Windows AD account) before users can go onto the web. One day while running updates from the web, I authenticated with my login - but I did not select the checkbox to save it to the keychain.
About a week later that user happened to come in on a Saturday. All of a sudden his machine is hitting our proxy server using my credentials once every minute. It must be running in the background because it never prompts him to login.
I have reset safari, manually deleted everything in the keychain, and used Tiger Cache cleaner ("deep clean") and it still does it.
Where else could this be hiding?
