Do you really have different users in shadow and in pam?

There's no need to have this twice.

Well, shadow and pam don't support extra fields, so I don't think you
can do anything about these unless you switch to another passdb.
Currently Dovecot doesn't support these kind of "pass through passdbs".

PAM however does support internally changing the username, so it would
be possible for you to create such a PAM module. But I can't help with
that.
