I followed the steps to migrate my namespaces to use Google's OpenID Connect implementation in ACS.
When I receive my claims from ACS, I have the new Subject claim containing the new Google NameIdentifier as expected. However, the "old" id in the NameIdentifier claim is not the same as the NameIdentifier I was receiving with Google OpenId 2.0.
The value of the NameIdentifier which I get from ACS depends on value"Use Google Open ID Connect" which is set in Windows Azure Management portal
Any idea what can cause this?
