[Dovecot] Extra_fields / first check userdb?

Thanks for the pointer Chris. It works now, using:
<snip>
auth default {
  mechanisms = plain login
  passdb passwd-file {
    args = /drbd/imap/dovecot-1.0.rc15/etc/userdb_extra
  }
  passdb pam {
  }
  userdb passwd-file {
    args = /drbd/imap/dovecot-1.0.rc15/etc/userdb_extra
  }
  userdb passwd {
  }
  user = root
}
<snip>

Where the userdb_extra file contains entries like:
username::2000:2000::/u/username::userdb_mail=mbox:/u/username/Mail:INBOX=/var/mail/%u
