Untrusted certificate or connection firefox warning inside actual PDF from PDF server.

Hi, followed instructions in question/answer here:

http://splunk-base.splunk.com/answers/4245/certificate-issues-with-pdf-server

I am still experiencing this problem even though I have installed a correct "cert-override.txt" in the correct directory. (Verified & Splunk restarted often) (underscore in file name, not -, this HTML editior turns my underscores into Italics, too busy to read about 'markdown').

Testing by hand from the Manager UI works fine, yes I have the latest version. Only fails and emails me a PDF with the Firefox 'this connection is untrusted' web page in it, when firing from an alert.

Do it by hand, all ok. doing 'ps -ef|grep splunk' reveals correct https url in the params being passed to Firefox

e.g. ...x86-64/firefox-bin -print @go?sid=scheduler">@go?sid=scheduleradminsearch-dGVzdCA0NTY-at-1312864440-f88fda574f3b4f78&media=print">https://NSW-JB-SPLUNK2:443/app/search/@go?sid=scheduleradminsearch-dGVzdCA0NTY-at-1312864440-f88fda574f3b4f78&media=print -printmode pdf ...

As you can see the URL in the search string is going from the instance with the PDF server app to the indexer which fired the alert. How to turn off or force the embedded firefox to trust the indexers its querying for the results if cert override txt doesnt work?

ANY help appreciated, cheers.
