Re: "They looked for the password on the CD . . ."
"Why were you looking there?"
If your job includes making sure security is managed, you look for such things - including under the keyboard/back of the monitor/in-out trays/top drawer (which is slightly excusable if it can be and is habitually left locked) or on the inside cover of a book on the nearest reachable shelf (usually the one that looks the most handled, surprise surprise)
Our standard policy is to lock all the accounts and replace the postit or whatever with one that says "Come and see security. NOW"
