Getting started with OpenID

Question

I'm looking to integrate OpenID into my website, but I need a tutorial to help me get going.

You can assume I have a good programming knowledge when making a recommendation :)

Answer 1

An excellent tutorial that explains how OpenID works can be found here:

Enterprise Java: Using OpenID

and shows you how to implement it using OpenID4Java (maintained on code.google.com)

Answer 2

Whatever you do, use an existing library. Few have read through the specs and lived to tell the tale.

Answer 3

openid

They have a handy little section on adding it to your website.
