Delete Stem
When this happens, we need to also delete the groups under the stem. We will have to keep track of the fact that those groups were deleted to handle any out-of-order later Delete Group calls.
Attribute Def Add/Update/Delete
In this set of operations, attributes may be used to control how a group appears in the endpoint system. One example could be adding a mail attribute to a group in the target system to give it an email address. The changelog entry should contain enough information for handling the management of this.
Membership Add/Update/Delete
When it comes to memberships, the one thing we need to keep in mind is that the Grouper SubjectID may not be the end-user's ID in the target system. This will necessitate a potential lookup in either grouper, the source of the grouper subjects, or some other translation table.
