Apple Safari fails to open AEM Document Security protected PDF documents

Hi,

I have secured pdf's using the AEM Document security server but users on iPad or iPhones are unable to open the secured document. I have followed the suggested workaround as per the URL below but it still odes not work and the error message is as displayed.

Just as an additional bit of information, the server URL is viewable from the Safari browser so is accessible.
