EmailAddressAlreadyTaken when logging in with an email address that's associated with a different OpenID identifier

[Guilherme Salgado]

As seen on OOPS-1556K2375, the user tried to login but LP didn't have that identifier registered so it tried to create a new Account/EmailAddress using that identifier. The problem, though, is that the email address associated to that identifier was already registered in Launchpad, so the user got the OOPS.

I'm tempted to just change the identifier associated with the registered email address to match the one given by the OP, but we should first confirm that no RPs are using these identifiers instead of the human-readable ones (https://launchpad.net/~user).

We cannot confirm that RPs have used these identifiers. That is information that the OP has, not us.

And in the end, we don't really care. We trust the OP, so if the OP comes back and says that the user has identifier XXYYZZ and that their email address is <email address hidden>, we should:

a) create an account for that identifier, if it doesn't exist
b) create the <email address hidden> email address, if it doesn't exist

But if the email address already exist, we should simply link the account to the person record owning the email address.
