Hi!

I'm a developer, and my company like to use the OpenID authentication for the user login. (We're following the adveices of openid.net, and our system worked correctly for last friday)
We recognize a problem, that Google changed the ClaimedID-s (or the autenticathion's return urls). It means: All users indentifier changed. It is a very serious problem, becouse we (following the openid.net advice) used the return url (the user indentifier) as unique ID in our database. So the login is not working now correctly.
Why happend this modification, and we have to count other modifications?
Currently, our system is not able to work correctly.

Best Regards,
