I have this certificate on my server:
DigiCert -> DigiCert High Assurance EV CA-3 -> wildcard.mydomain.com
And if "DigiCert High Assurance EV CA-3" is not installed on the client machine I will get a error from the browser that is server certificate is not valid. If I installed it manually it's working fine.
But if I go to i.e. https://github.com I can see this certificate chain in the browser:
DigiCert -> DigiCert High Assurance EV CA-1 -> github.com
If I check in my user certificate store via certmgr.msc I can find the Root CA (DigiCert) but not the immediate certificate. Why is this working?
Maybe I can setup Apache to send the immediate certificate to the browser?
