All I need to do is maintain email address format firstname.lastname@domain, I do not need these as either unix/windows(samba) usernames. Currently these are a mixed bag of firstname, initiallastname & lastname. One step on the migration is to at least standardize the new ones.
Than simply use virtusertable (if you use sendmail, or whatever is postfix equivalent if you use postfix) to map email addresses in first.last@domain format to actual usernames. This is kind of standard thing to do, and I'm surprised you haven't done it that way while you were on courier too.
