Ticket 50077 - RFE - improve automember plugin to work with modify ops
Description:
Previously automember was only invoked for ADD operations. This enhancement
allows it to work with modify operations, and it will also maintain the
correct memberships. So if a modify changes which groups the user would
belong to, it will add the user to the new group, and remove them from the
old group.
