Anyway, another thing that continually amazes me is how many people don't understand what account locking is all about. We get many calls every day from people whose account has been locked, and almost all of them ask why it was locked. It's always the same answer. It's been the same answer for fifteen years. You got your password wrong too many times. Every Windows/Active Directory environment does it.
Nu-hu! I'm sure I remember my password. Your system must have changed it!
Seriously the number of times I get accused of "changing" or having a system that just randomly changes passwords in an average week is a bit high.
