Grouper attestation means marking a group or folder so that owners must review the membership list periodically.  This is useful in ad hoc groups where deprovisioning is not automatic.  Owners will be reminded by email to review the memberships.  After reviewing the memberships, the group owner will click a button on the group indicating that it has been reviewed.

This is in the 2.3.0 API and UI patch (TODO list patch number)
