These are in the grouploader_log table, one entry for each run of each loader

Thanks for thorough testing

Hmm... this is kind of a tough problem... I would need to know that a group
which is no longer in the loader needs to have its membership list deleted...
this is not solved in any release yet, would require some thought and design.
Currently any group in the returned sql is managed by that loader run, but
now we either need to remember that a group was associated with a loader job,
or have another way to identify it (maybe the loader job have an attribute
which identifies a pattern of group names, e.g.
grouperLoaderGroupListPattern: myschool:orgs:% (regex would be nice, but it
needs to be efficiently queriable with SQL). Then I guess any groups that
match that pattern which are not in the returned SQL would have their
memberships removed. I think we would need to remove membership and not
delete the group so the group name and ID are reserved in the namespace (e.g.
if another group is using one of the generated groups as a composite). Maybe
deleting the empty groups could be a manual process? Or maybe there is an
option whether you want to delete the group or just remove membership?

Does that work for you?
