To request a wildcard certificate, follow the steps below in the LoadMaster User Interface (UI):
  1. Go to Certificates & Security > ACME Certificates.
  2. Click Request New Certificate to request a wildcard certificate from the DigiCert Certificate Authority (CA).
    Note: All fields on the Request a New Certificate screen are optional except for Certificate Identifier and Common Name. You must select a Virtual Service and DNS provider (including related credential parameters) next to the Common Name field.
  3. Enter the unique identifier for your certificate in the Certificate Identifier field.
    Note: The Certificate Identifier value must be unique for all certificates on the LoadMaster.
  4. Enter the Fully Qualified Domain Name (FQDN) of your web server in the Common Name (The FQDN of your web server) field. For example, *.example1.com matches anything that ends in .example1.com.
  5. Select the Virtual Service that is used for this domain. This will be used for the validation challenge to prove ownership of the domain.
  6. Select the DNS provider API from Select DNS API drop-down.

    For wildcard certificate validation, the DNS-01 challenge type is used. This requires the addition and removal of temporary DNS records. For automatic DNS record updates during wildcard name validation, you must select your DNS provider from the Select DNS API drop-down list.

  7. Set the access credential parameters for the selected DNS provider. The fields to fill out vary depending on the selected DNS provider.
    A list of DNS providers is as follows:
    • Progress-LM-GEO
    • CloudFlare
    • GoDaddy.com
    • Azure-DNS
    • DNSMadeEasy
    • DigitalOcean
    • NS1.com
    • Amazom-Route53

When you are finished setting the relevant fields, click Request Certificate to create a new wildcard certificate request using the specified data. It can take approximately 25 seconds to generate the certificate request. If the request fails, you must fill out the form again.

A list of issued wildcard certificates and related details are displayed at the bottom of the Manage ACME Certificates screen.
