How to Check if a .NET Passport is valid before accepting the user.

Hi,

I am wondering how to make a PHP Script so when someone enters their email address (.NET Passport) and password on my own webpage it verifies it with Hotmail to check if the account and password is real. If the address is real it passes them to "valid page" and if it isnt it passes them to an "invalid page"

I know that it's possible, because eBay etc used to let their clients used their .NET Passport (email address) to login.

It might be possible to use a POST/GET-REQUEST to Hotmail and check for the words “Invalid Password” and return the “Invalid Password Page”, and if the password and email address is correct then return the "Valid Password Page"?

I just started PHP not very long ago so my PHP skills are not the best so please help. :)

Thanks in advance,
Peter :)

Welcome to WebmasterWorld ice39,

we messed around with this a bit to try a web based msn type client, I will see if I can dig up any old code tomorrow, as I don't have it here at the moment.

AFAIK Microsoft is canning it, not least because there were so few people using .NET Passport.
