SSO Authentication (Standard Mode) suddenly requires authentication for Content Server sites.

Hi All

Yesterday afternoon (03th December aprrox 14:00) most sites that have analytics, which is most. Is all of a sudden asking for credentials.

The proxy server has been working perfectly for approx 3 years now without issue or recent change.

Original web site http://news.sky.com/entertainment for example.

I have checked the web log for events and discovered that the user is accepted for the initial site but does not pass credentials for the "Content Server" sites.

Could it be a problem with surf protection?

Any Ideas.

Many thanks
