Is it possible to access interactive PDF through windows logon( windows may have multiple user accounts). On one particular account , if the user enter login credentials--(if valid)--then he should access the paricular pdf( fill & submit vice versa.).
You can try extrating the xml data from the XDP form and re-render the XDP form with the extracted xml data plus a static PDFFormRenderSpec. Make sure the PDFFormRenderSpec is set to RenderAtClient as false.
