We have "modifyTimestamp" attribute in most of our objectClasses and it mirrors the meta.lastModified operational attribute value. We filter and sort based on this modifyTimestamp in our queries, so would like to setup an ordering index to make these queries fast. I seem to remember discussing the "equality-index-filter" definition with a list of comma separated objectClass is not supported, though dsconfig accepts this definition and that these should be created as separate index per objectClass. Is my memory on this right?
We tried setting these up as a separate index, but are seeing an error that an index with the same name exists (i.e. when we try to add the second index on 'modifyTimestamp' for the second objectClass on the list). Can you please help clarify?
