Do you have more information about the creation process?
It's pretty straightforward the certificate process, CSR and applying it.
Can you share the commands and the template that you used for the creation?
First I have used template:
CN=FQDN for vidm
next I have cd down to CertgenVVD => Set ExecutionPolice Unrestricted => .\CertGenVVD-3.0.4.ps1 -vaidate => .\CertGenVVD-3.0.4.ps1 -MSCASigned -attrib 'CertificateTemplate:VMware'
Once successfully created I have 2 certs one of them ending .chain.pem & .pem where I was uploding to vidm .pem.
