I am desperately seeking an answer to this.
I have a company that wants to use HTTP Post to log into my company's web site. That is the easy part.
The difficult part is... they have an intranet. Each one of their employees has a unique log in to go into their intranet. After they log into their intranet, then they want to be able to click on the link and post into our web site with a specific username and password assigned just for them.
How would the company set it up so the link has that username and password in the HTTP Post code unique to whomever is signed onto the portal?
