Provisioning Framework is provisioning entities that exist in Grouper but not Target

We have encountered a bug in the Provisioning Framework whereby if an entity exists in grouper but not in the target (i.e. OpenLDAP) grouper will insert the entity in a provisionable group. This is a critical bug because grouper is not the entity source so should never add one if it does not exist in the target. Our production Grouper v2.6.8 and we plan to upgrade to v2.6.15.1 within the next two weeks. We have tested this in our stage environment which is running v2.6.15 and it the issue persists
