Auto-expiring passwords

In ASIP 5/6, I believe there was an option to force users to change their password every x days. I found this to be a good security measure. Also convenient was an option to require a new password at the next login. I have a customer with OS X Server 10.1, soon to update to 10.2. I didn't see an option in 10.1 for this, nor in a quick browse through the 10.2 admin guide. Is there a way to do this in 10.1/10.2 Server? I'm thinking specifically about AFP logins from OS 9/X clients. I suppose there could be a conflict with non-AFP logins (one can't require a new password via FTP) but I don't see that as a concern in this case. Thanks, Mitch
