ldapsearch by aliased objectClass

Hello,

I've created an alias by following the FAQ at https://www.openldap.org/faq/data/cache/1111.html

dn: uid=alias,ou=People,dc=example,dc=net objectclass: alias objectclass: extensibleObject uid: alias aliasedobjectname: uid=target,ou=Retired People,dc=example,dc=com

The problem I'm facing is that this needs to be queried by an application (out of my control) that queries LDAP looking for a particular objectClass, like this:

(&(objectClass=person)(uid=alias))

This query misses the alias, I guess because the alias object has just "alias" and "extensibleObject" as classes... Is this expected? Is there a way to work around this, server-side? I mean, to tell the LDAP server to look for "aliased" properties?

Many thanks for your time!
