I use my Google Account for logging into OpenID-enabled websites. In my website, I added the following meta tags:
When I then use my website URL (http://blog.dantup.com) in an OpenID login, it redirects me to a Google login page, which requires that I login as "danny.tuppeny", and sends me back. Logging in as another Google account doesn't work.
Recently, I noticed I was able to login to another OpenID site using a Google Apps user (user@mydomain.com). If possible, I would like to amend my meta tags, so that Google requires my Google Apps user instead of the Google "danny.tuppeny" user. This is because now that Google supports Apps users for most services, I'm trying to migrate most things to my Apps account.
So... What do I need to change the meta tags to in order to use user@mydomain.com. Currently Apps accounts don't have Google Profiles URLs, however since I can login to other services (eg. Disqus) by clicking the Google logo and logging in as user@mydomain.com, I presume this is still possible.
Since Google+ went live for Google Apps yesterday, this is now possible! Just put your profile URL for openid2.local_id. Eg, this is what I have in the <head> section at blog.dantup.com:
<link rel="openid2.provider" href="https://www.google.com/accounts/o8/ud?source=profiles">
<link rel="openid2.local_id" href="https://plus.google.com/113181962167438638669">
This allows me to use 'http://blog.dantup.com/' to login to sites like StackOverflow using my associated Google Apps account, and they'll receive 'http://blog.dantup.com/' as my identifier, allowing me to change to a non-Google account in the future (if required) without updating lots of websites!
