Imagine this scenario:

1) Peter Pope is hired. He gets the username "pepo".

2) Peter Pope makes 5 tickets over the years.

3) Peter Pope quits his job, and the username "pepo" becomes available.

4) Petra Potter is hired and gets the username "popo".

After SD syncs with the Active Directory, Petra is assigned Peter's tickets and names, so when she makes a ticket she will appear to be Peter. I'm thinking this is because old cases and such are kept for so it's always possible to account for activity by people who may not be in the company anymore, which makes sense.

I'm looking for some ideas about how other people handle this issue.
