[otrs] Looking for a way to allow managers to see their employee's tickets

Hi, I'm currently using OTRS 3.0 (but willing to upgrade if needed). I've been asked by my boss to try to find a way to allow managers to see their employee's tickets. We use LDAP (AD) for customer backend. Is there a way to achieve this in OTRS. Actually, it would be great if we could do that for all managers, but it is mostly for one manager. If I could tell OTRS to allow this person to see the tickets opened by her employees it may be sufficient. Thanks, Ugo
