I am webmaster for a non-profit and we use Google Apps in our domain email and selective google app uses. Officers in the non-profit want to use a blog for announcements and whatnot so I decided that wordpress would be good because I found the OpenID plugin to be used for that purpose. However it failed for me. I got the error:
Could not discover an OpenID identity server endpoint at the url.....
Upon looking into the issue more, I found that it wasn't an issue on my end. I've found that Google's special OpenID service for Apps for Domains requires OpenID relying parties to implement a special (proprietary) discovery mechanism. Upon researching the issue for a while I've found that there are a number of OpenID RPs and that not all of them support google's discovery mechanism. One of those is called RPXNow. I was able to test our google apps implementation against a site whose openid rp supports google's discovery mechanism (jyte.com) successfully. I was wondering if the OpenID plugin could be changed to do the same?
