RE: Password changes more than once per day

[Joey Peloquin <jpelo1 () jcpenney com>]

Bob,

It actually works in tandem with the 'Enforce Password History' setting,
preventing users from resetting their password several times in a short
period.  For example, if Enforce Password History is set to remember 10
passwords, and the user's password has no minimum age, they could change
their password 10 times, effectively allowing them to use the same password
forever.

Maybe it's time to remind the user *why* we have password policies in the
first place?  Sounds like they'd be happy to circumvent the policy
altogether.
