<div>I don't see any mention of this in MS-ADPS, but am not sure where next to check.</div>
<div><br>
</div>
<div>In particular, while I have reproduced the rollover for 'must change now', I'm wondering when the password otherwise rolls over, is it before the expiry (eg with the 'old password allowed time' grace of 60mins for example, or at the expiry?</div>
