For single sign on across apps, you have to persist the sign on. In your PHP
app, save something that you can carry with you in the ASP.NET application.
You can then pull the user's info and store it in session, if you desire.

Cross product authentication makes things hard, as PHP does not respect IIS
logins. One day this may not be the case, but it is right now. I would
consider passing the user's info in the header encrypted in some way. You can
then pull it out in your "login" form and send the user to the page he
requested if the header information matches an account (which it will if you
coded correctly).
