You need to configure the domain controller to trust the Certificate Authority that issues the smart credential.
Note: If the Identity as a Service Certificate Authority resides on the Domain Controller, then this step is not required.
Configure the Domain Controller to trust the issuing CA
1. Export the CA trust chain:
● For an Entrust Managed PKI Certificate Authority, see Export an Entrust Managed PKI CA trust chain.
● Microsoft Certificate Authorities not tied to the domain controller, see Export a Microsoft CA trust chain.
● For PKIaaS CA issued smart credentials, see Configure domain controller certificates.
2. Run the following commands on the domain controller to trust the CA
certutil -f -dspublish trustedca.cer RootCA
certutil -f -dspublish intermediateca1.cer NTAuthCA
certutil -f -dspublish intermediateca1.cer SubCA
certutil -f -dspublish intermediateca2.cer NTAuthCA
certutil -f -dspublish intermediateca2.cer SubCA
