I am not using AD, though instances of AD exist in our environment
that hold mail data mirrored from non-AD LDAP masters. Our
Unix LDAP servers have single-valued "mail", and multi-valued
"mailalternateaddress". Perhaps at the schema-level "mail" is in fact
declared multi-valued, but if so, all our tooling ensures that it is
not used that way, we only allow multiple values for mailalternateaddress.
It is sensible to have a designated attribute for the primary (canonical
if you like) email address. If the RFC LDAP schemas don't support this,
that's too bad for the RFC schemas.
