I'm trying to install a signed SSL certificate. I can't work out how to add the CA certificate bundle (issuers certificates) separately, I've tried appending them to my cert but doesn't work at all.

Without the CA's bundle the certificate sort of works - but good old IE8+ seems to have some sort of additional security preventing SSL connection at all if the root certificate is not already embedded.

It works ok if I visit a website hosted on the same machine with the certs installed properly, then revert to the KWS on port 4430. But new users that haven't cached (presumably) the certificate 1st get connection errors in their browsers.

I presume I need to build a single bundle, but I must have got it wrong order before. This is on a Windows platform running Apache/OpenSSL.

I'm running v2.0.0 beta 3#17
Any clues anyone?

Don't worry - found the fix here

Would be useful to make this a 'sticky'

I don't know if it works with current version of kerio but in 6.x i've chained the two files into one single file and put that as the certificate in kerio. No need to edit any preference.
like this:


first mine then the intermediate certificate

Yesterday I was able to load our wildcard cert (*
To creat the crt file, I copied and pasted the contents of following 4 files to create my .crt file.


When imported with the .key file, worked find.

Hope this helps.
