Is it possible through IIS?
Person A who's computer is in Domain A logs into a website that is in Domain B. They are prompted to enter in their crendentials to Domain B, which they do and then they are authenticated and able to get in. Then in that the website, there is a link to another website that is in Domain B but on another server. When they click on that link, they are then prompted to put in their credentials for Domain B again. Is there anyway around it so they don't have to put in their credentials twice?
