Two of our users suddenly started having problems viewing their printouts in iNav. I actually opened a PMR, sent traces, etc, till we figured it out.
System i passwords cannot start with a digit.
If you change your password to something that starts with a digit, the System i will put a "Q" in front of it automatically. Sometimes, anyway.
If you're coming in to the System i from a Windows PC, and your Windows password starts with a digit, and you have iNav configured to use the Windows username and password without prompting, the Windows password will be passed , at least in some cases, WITHOUT putting a Q in front, causing problems.
Moral: Don't start passwords with a digit.
