Customer Portal

Customer Portal

I have created a customer portal with multiple forms & reports and two html pages - one containing an embedded form & report, and the other an invoice template.  I have set all the Module-Level permissions to access for the report.  The forms and reports can be accessed fine by the customer portal user, but when the portal user hits the html pages - they are prompted for another log-in?   

One thing of note - If I am logged in as a zoho user in another browser, they portal users can access the HTML pages.  If I am not logged in, they get the log-in prompt.  What am I doing wrong?

Thanks!
