Working on deprovisioning
if you deprovision a user they end up in a group
Putting logic in place so on the UI, add this subject to this group, will give an error message ,“you can not add this member to this group , that member has already been deprovisioned”
Configuration: If someone is deprovisioned do you want them to be allowed back?
Default is no

This was requested from Harvard…
