Is there any way that I can use REST, SOAP or JSON to authenticate users using Google OpenID or Google OAuth? The server that I'm required to use is very incompatible with PHP (rendering the existing OpenID and OAuth libraries for PHP useless) and I don't foresee it being worth the trouble of installing PHP and making sure that it's working to verify users using PHP. I'd rather make users create their own account for my website than use PHP to verify their Google account (because this project will be internal to my company).
Is there any web service out there that would allow me to use REST, SOAP or JSON to verify a user using Google OpenID or OAuth?
