There is some truth to the 7 alphanum. password theory. There is a fine line between complexity-security and end user-usability. While the longer password may be more "secure" or more difficult to crack, it will fail when the user, who can't remember that long alphanum. password, writes it down on a sticky note and hides it under his/her keyboard. Ultimately, we're talking about END USERS here and not security minded IT people. End Users will always be the weakest link so you MUST accommodate them in order to have an effective Password Management Policy. You can have them change passwords every week and make them include non-alphanum ascii characters, make the password be more than 7 characters, and I guarantee you that your network will be more vulnerable as your end users will get fed up and simply write it down. That and you'll invest some $$ in Aspirin for your Administration Headaches as you'll be inundated with phone calls from users who didn't write down their password and forgot it. Personally I prefer passphrases to passwords.
