We have a GlobalSign Domain certificate for our domain. I've installed the certificate into IIS and added the GlobalSign Domain Intermediate certificate to the Intermediate certification authorities for the local computer
It seems that IIS is not sending through the intermediate certificate (causing an error in firefox), just the domain certificate. I've verified this with OpenSSL and also various websites including GlobalSign's own health checker.
Looking In IIS, I can follow through the chain and each certificate is "ok", without the option to install any indicating they already are.
Any ideas on what may be wrong?
