You can now see information about deactivated employees. This allows you to change the user ID for a user record, so user IDs can be reused.

E.g. James Bond (user ID jbond) has left Organisation X.  A new employee Jenny Bond has started and has been allocated the user ID jbond in Organisation X’s active directory.

In the performance system, Jenny’s record would error when importing because the user ID is already allocated. 

You can now change James’ user ID to something unique e.g. jbondOLD so that Jenny can have jbond going forward.
