No. LDAP supports robust distributed caching via replication. If you
want local caching on a MTA, field an LDAP replica on the MTA or
dedicate a suitable replica on a nearby machine to the MTA.
LDAP caching in the LDAP library was buggy, and has poor semantics.
Support was withdrawn in OpenLDAP, not just Postfix. This is NOT
coming back.
