TL;DR; Explains how to set up and link a Windows Live ID with OpenID for testing, enabling single sign-on and unified authentication across supported web services like Plaxo.

It seams that Microsoft is making an attempt to integrate with OpenID. With the announcement that “ Windows Live ID commits to support of OpenID ” I thought a little investigation would be in order.
You need to setup a new Live ID on the Live-INT service, you can use any email, but make sure that you do not use your production password!
Go to https://login.live-INT.com/ and use the sign-up button to set up a Windows Live ID test account in the INT environment.
Go to
https://login.live-int.com/beta/ManageOpenID.srf
to set up your OpenID test alias.
You alias will be “http://openid.live-int.com/[yourAlias].
You can then associate an open ID with a site. Here is the experience with Plaxo:

From the Plaxo homepage, click “Settings”…

Then select “Identities” and “Manage your OpenID’s”.

You can then attach any number of OpenIDs to your Plaxo account. So lets click “Attach a new OpenID”.

And then “SignIn”.

This is where Windows Live takes over from the main sites, and you enter your password for your Live account.
I am hoping that they will be releasing a version that works for .NET applications and not just websites. This would allow application developers to join the ranks of interconnected authentication application with single sign-on.
It is a dream I have…
