Installing DigiCert Commercial Certificates

 - This article is a Work in Progress, and may be unfinished or missing sections.

Obtain all the certificate files from Digicert and place them in a folder /tmp/digicert on your Zimbra server. Then create commercial_ca.crt as described below and verify and deploy:

mkdir /tmp/digicert
cd  /tmp/digicert
wget https://cacerts.digicert.com/DigiCertTLSRSASHA2562020CA1-1.crt.pem
wget https://cacerts.digicert.com/DigiCertGlobalRootCA.crt.pem
cat DigiCertTLSRSASHA2562020CA1-1.crt.pem > commercial_ca.crt
cat DigiCertGlobalRootCA.crt.pem >> commercial_ca.crt

cp example.com.key /opt/zimbra/ssl/zimbra/commercial/commercial.key

zmcertmgr verifycrt comm /opt/zimbra/ssl/zimbra/commercial/commercial.key /tmp/digicert/example.com.crt /tmp/digicert/commercial_ca.crt

# should return OK
zmcertmgr deploycrt comm /tmp/digicert/example.com.crt /tmp/digicert/commercial_ca.crt

# to load the changes:
zmcontrol restart
