Issue I ran into setting up my own similar system. When Postfix gets multiple values for the destination email from an LDAP lookup, it duplicates the incoming email for each result and tries to store each one in a mailbox for each of those emails. Since Dovecot is probably only configured to use the primary email address as a mailbox, this fails, and a bounce message is sent for every email that isn't the one Dovecot has a mailbox for. If Dovecot does have a mailbox for the alias, that's likely unintended because the intended recipient of the message will not see the email (since it's in a different mailbox).

Probably shouldn't merge it yet, since this should also probably be extended to the LDAP search queries for mail and alias lookups.
