[`bug 1787874 <https://bugs.launchpad.net/keystone/+bug/1787874>`_]
The default value of the config option `unique_last_password_count` is
changed from 1 to 0. Now `unique_last_password_count = 0` means password
history check is disabled. `unique_last_password_count = 1` means
when changing password, the new one should be different than the current
one.

Please note that the deployment which sets `unique_last_password_count = 1`
in the config file should update the value to 0 to keep the same behavior
as before.
