I have been trying to include the memberOf attribute in a new objectClass. If I just set it to "MAY" (for example), it complains about using an operational attribute in my definition. I have seen quite a few Q&As about this, but I am really trying to understand where this issue is originating. Maybe I haven't looked at the right one yet. OpenDJ has the ability to utilize it in custom classes, so I was hoping to be able to also do the same in OpenLDAP. Thoughts?
