When I was working at Coreworx in Canada I introduced an internal knowledge base in the form of MindTouch (then DekiWiki). I got involved in the community around the project, and ended up meeting the developers behind it in San Diego.
I evaluated it for a project at Symbian, and in order to try and make it suit us better I wrote a module for using OpenID.
Today, MindTouch have published a couple of posts I wrote on the subject, which I am happy to share with you here:
In other news, over the course of the next few weeks, I'll be running a series on the migration of Symbian's LAMP/LTMJ (unfortunately Linux/Tomcat/MySQL/Java doesn't have a vowel in it) hosting servers to Amazon EC2. Stay tuned!

This is great stuff... just a query to see if this works with Google Apps (Premier) accounts ?
Try entering "https://www.google.com/a/example.org/o8/ud?be=o8" as your endpoint.
You can set up discovery docs so that you can just enter "http://example.org" and OpenID will do all the rest; have a look at this post to see how.
