I recently bought an SSL certificate from Comodo, and when I got my certificate I also received two intermediate certificates…
The problem came when trying to import the two intermediate certificates… on the Synology DSM 5.0 firmware, there’s only one field for the intermediate certificates…
So how did I get both certificates into the one file? It’s actually really simple - I combined the two certificates into a single, .crt file and then selected the combined file as the “intermediate certificate”. The web server reboots and then there are no nasty Firefox/Crome errors like “sec_error_unknown_issuer”.

As unlikely as it seems this does actually work. Thank you very much. I wanted to install Starfield certificate with the intermediate but it was not easy. Thanks to your article I was able to resolve the last issue I had. I exported the two intermediate certificates from the p7b file - note for newbies, it has to be exported as Base-64 .cer file. Then merged them together in Notepad and saved as UTF-8. The I was finally able to import it. Thanks again
