If you do not enter a license for the QVS (QlikView Server service) you won't be able to configure it as the service will still run but remain in "unlicensed" mode. IIRC the AccessPoint should show a message like "No Server" because the QVS is the one that sends thumbnails of available documents to the Web Server and the AccessPoint page.
And if you can't show any documents, it's no use to configure users.
Is there a problem with showing a particular document on the Production machine? In a separate area? Or - if it's only for demo purposes - in a licensed QV Desktop? With the latter, you'll be able to move your document off premises...
Plan a reference visit to another customer or to your office (if you have a QlikView Server at the office), or
contact your Qlik Account manager, discuss the opportunity and ask for an SIB Temporary license. If this is a decent Sales opportunity, it won't cost you anything and you'll be able to use and demonstrate all QV Server features for a period of time.
