Re: pplolicy lockout grace time?

Hello

We ran into the following problem: someone changes its password, but
has a few devices with the old password recorderd. Before the user
has time to update stored passwords, an buggy-client hammers servers
with requests using the old password, and get the account locked by
slapo-ppolicy.

Perhaps there could be a setting in pwdPolicy or in slapd.conf
so that there is a grace time after a password reset? For instance,
the admin could configure that slapo-ppolicy should not lock a user
if password has been changed less than X seconds ago.

Opinions?

Opinions:

First of all, password lockout itself is a dumb idea, and we only implement it because it's part of the original ppolicy spec. The ppolicy spec is pathetically bad though.

As for a grace time - that sounds like a terrible idea too, since sometimes passwords are changed with some urgency, specifically because of the imminent danger of an attack/fraudulent use.
