I can't see how to prescribe periodic passwd change, only how to set expiry time. At the moment I put the following line in the root's crontab: 2 2 2 * * pw usermod shterenl -p "`date '+\%d-\%m-\%Y'`" This makes a user's passwd expire once a month. Is there a better way to force users change their passwds periodically? thanks anton
