On Monday, July 17, 2006, MSU's Kerberos service will enforce a rule that will prevent users from re-using any of their last four passwords. This will apply to password changes via netid.msu.edu, including when a NetID is reset using the PID and PAN. This change is being made to comply with best practices in security. This requires a minor configuration change in Kerberos and is scheduled for 7:00 a.m. No downtime is expected. /rich
