Zimbra SSL Certificate CSR Creation

Zimbra CSR Creation

1. Log in as root.

2. Adjust the following command to match your information: /opt/zimbra/bin/zmcertmgr createcsr comm -new "/C=US/ST=Utah/L=Lehi/O=Company Inc/OU=Department/CN=your.domain.com" Where:

   C = 2-digit country code

   ST = State/Province

   L = City

   O = Organization Name

   OU = Department (e.g., IT Department)

   CN = Common Name (mail.domain.com, *.domain.com)

   If you want to include more than one name in the CSR, you can add -subjectAltNames to the end of the command. Example:

   /opt/zimbra/bin/zmcertmgr createcsr comm -new "/C=US/ST=Utah/L=Lehi/O=Company Inc/OU=Department/CN=your.domain.com" -subjectAltNames "www.domain.com, secure.domain.com"

3. Running this command will output the CSR to the following location: /opt/zimbra/ssl/zimbra/commercial/commercial.csr

4. You will use the CSR to place the order for the certificate (select “Other” as the server software when placing your order).
