Comment 1 for bug 770107

This exact problem happened to me and my account.

I lost my domain for my mail which was the default (and only) email address entered in launchpad.net (and login.launchpad.net)
As I didn't connect for 2 years, I didn't remember the password, so I asked the reset. But I couldn't receive the email since I didn't have my domain.

So I asked the login support to change my email information on launchpad so I can reset it with my new mail. No answer.
Then I thought about asking someone on IRC. Laura Czajkowksi gently asked me to send a message to <email address hidden> describing the problem.
She followed quite nearly my problem and told me it was done : my mail has been changed on launchpad.
I tried to reset it, indicating my new mail. I received a new mail from launchpad, telling me that someone try to reset a password of a launchpad account linked to mail, but no account were linked to that mail address.
It left me dubitative. My problem was still unsolved. I thought nothing has been done.

I could get my domain back, it was a patience work, but it was worthwhile. I reinstalled a temporary postfix just to get my address working, and tried to reset my password with my old email.
I got the email, could reset my password and access my 2-years-unlogged account ! Finally, I saw that the launchpad team DID change my mail account, they add my new mail and made it default.
Though, when I try to reset my password of my new mail on a new browser session, just to understand, I got the same message telling me that no launchpad account were linked to my new mail.

Coming home tonight, I logged in again with my new mail : error, mismatch password.
I thought that my old mail was still in a database somewhere. I tried with my old password, bingo.
But now, I was on my ~dolanor account page on login.launchpad.net telling me that my default mail was my ancient mail. So I added my new mail and put it as default. And now, trying to reset it with my new mail in a new session on login.launchpad.net worked and I got the code.

So the launchpad support people did change my mail in my launchpad.net account, but not in my login.launchpad.net and I couldn't use the reset form.

I think those kind of info should be connected/sync'ed
