When running a Policy Server, even if a given user has changed its
password, it can still use the old password to login into the
application as well as the new password for 5 minutes after the
password change. So for 5 minutes, the user has 2 valid passwords.

This happens with the self change password in which the user receives
a temporary password.




The issue is due to the OldPasswordAllowedPeriod parameter value on
Active Directory User Store registry (1).




- Configure OldPasswordAllowedPeriod to solve this issue;
