I recently purchased a domain name. We'll call it example.com. The previous owner of the domain had a Google Apps account.

Now that I own the domain, I want to create a Google Apps account so I can point the domain www.example.com to one of my Google App Engine domains. We'll call it application.appspot.com.

Google App Engine won't allow me to add the domain without verifying ownership by creating a Google Apps account or logging into Google Apps, but I don't have access to the old Google Apps account.

We've tried going to this address to take ownership: https://www.google.com/a/cpanel/example.com/ResetAdminPassword?c=LONG_KEY&hl=en_US

We retrieved a new password, but it wouldn't tell us what the login name is. How do you find out the login name?
