--- Comment #1 from Howard Chu hyc@openldap.org --- Yes, changing the canonical name of attributes in RDNs will break the dn2id index, because that index uses the text of the canonical name. After a schema change like this the attribute name will no longer be recognized.
You may be able to regain access to these entries by adding a new attribute definition that uses the old name. Then do a modrdn to rename from old to new name. Of course you can't use the old name as an alias in the existing attribute until all of these instances of the old name are gone.
