But the username in the authentication db is completely independent of any
localpart that might be used to deliver to a mailbox - access to which is
authenticated by providing creds for that username.

I don't see how the fact that MTAs may or may not consider localparts to
be case-sensitive has any bearing on the case-sensitivity of usernames
stored in the authentication database.
