Poidsy is a set of PHP scripts that serve as an OpenID consumer. OpenID consumers allow users to authenticate themselves with an OpenID identifier. For more information about OpenID, see openid.net.
At the time of writing, there were several consumer "libraries" available for PHP developers. From what I saw of them, they all exposed far too much of the OpenID logic to the implementor for my liking — you pretty much needed to build your own consumer using their libraries, rather than simply using a pre-made one.
If you want to test the OpenID consumer, enter your identity below. You should end up on a small demonstration page which will either confirm your ID or inform you of any errors that occured. The demo script is included in the releases below.
The current version of Poidsy is 0.6. At this stage, Poidsy has support for both OpenID 1.x and 2.x, as well as a couple of extensions to those. If you encounter any providers that do not work with Poidsy, please contact me.
Instructions for integrating Poidsy with an existing login script are available.
If you're using Poidsy (or are trying to but are having problems) then I'd love to hear from you. My contact details can be found on my personal website.
