If this behavior is changed, you'll need to find another way to delete

I'm not sure if that this is true, ldappc makes two deletions, first of
all it deleted groups which do not match the objectClass of the
provisioned groups, and then it deletes all groups that do match the
objectClass of the provisioned groups but which did not match the
searched grouper groups.
The first set of deleted groups would never have been provisioned by
grouper anyway (barring configuration changes), and it was these that I
suggesting don't need to be deleted.

I see. And rather than using the group objectclass to distinguish groups that "belong" to Ldappc, perhaps it could be useful to mark them in some other attribute (eduInternet2LdappcInstanceId maybe, especially recognizing that some sites wish to run multiple instances of Ldappc, each "owning" their own slice of the grouper db).

The down side is that if we do so (either use a custom attribute, or fail to "own" all groups in a given ou), Ldappc will be unable to provision standard group objectclasses. It would require a schema extension to the DSA.

Of course, you probably only get full value from Ldappc if the DSA's schema is extended, the way things are now.

We could make an option, or add some features to the XML file. This shouldn't be too hard to do without breaking anything.
