barracuda only supports ldap user verification. to get around it, we
wrote a script that dumps mysql user db into ldif format that barracuda
recognizes, then imports into openldap (runs out of cron). a disgusting
hack, but its the only way to get smtp-time user verification info into
the barracuda.

other mail-washers are more flexible in their import methods.
