Unable to set password history to 0 when "Check password on Notes id file" is enabled via policy

Problem

You have enabled the "Check password on Notes id file" option in a security policy.
By default, "Password History (Notes only)" under "Password Expiration Settings" section is set automatically to 50 passwords.
You set the password history value to 0, then saved and closed the document:

You opened the document again and observed that the "Password History" was set back to default value (50).

Cause

The minimal value you can specify in this field is 1. At least one password (actual) needs to be saved in the password history of the ID file

Resolving the problem

Set the "Password history" value to 1. Save and close the document.
