We have this PHP web app that a certain group of users user that requires
them to log in. The way the system is configured this is the first page
that comes up for them in the browser and we want them to log in to it
first. After they get logged in we want to have a field where they can
enter in a URL then click submit and have their authentication
credentials forwarded to BorderManager to single sign them in and take
them to the external website.

Does anyone know how to forward the username and password to
BorderManager to get this to work?
