"Minimum number of days" isn't a very bright idea.It is, for a low minimum number. The rationale is to avoid the user reusing passwords: Ok, so my password is 12345678 and I must change it now? Let's do it: 87654321; but immediately I change back again.The way to do it is to have a record in your password db of the hashes of each user's last N passwords.BTW, how do you do that?
OpenVMS does that for you. Don't know about Linux. -- Seek truth from facts.
