Wanting to know how I use a trusted certificate so we no longer receive the certificate warning when going to the vSphere Web client page. have looked around but there doesn't seem to be a straight forward answer. My knowledge around certs aren't great.
You have two options..
1. Download trusted root of vmca using the below kb to avoid certificate warning
2. Replace machine ssl certificate with CA certificates using certificate manager utility

If your organization wanted only internal CA or third party CA certs as their security policies then second is go to option..
kindly find the following, step by step configuration:
