Decrypt integrity check failed while changing password

[Brian Davidson]

Ken,

You, of course, are brilliant.  Setting the history to 1, and then back 
up to 10 seems to fix it.  I realize that a side effect of this is that 
users can reuse any of their recent password the next time they go to 
change their password.

Thanks!

Brian
