Make sure these prerequisites are met to use third-party ACME clients with DigiCert​​®​​ Trust Lifecycle Manager.

User permissions

To manage certificate profiles for ACME-based automation, assign the user role of Manager or Certificate profile manager to the user in DigiCert® Account Manager. Alternatively, assign a custom user role that includes the Manage profile permission.

DigiCert® CA Manager issuance

To use a third-party ACME client to request private certificates from DigiCert® CA Manager:

  • You need at least one issuing certificate authority (CA) set up in DigiCert® CA Manager.

  • For DigiCert® CA Manager issuance, you need Server seats allocated to the business units where the certificates will be deployed. To learn more, see Seat management.

For help verifying or meeting any of these prerequisites, contact your DigiCert account representative.

Additional requirements for private on-premises DigiCert ONE users

Users with a private on-premises DigiCert ONE deployment need to install the private DigiCert ONE certificate into the local truststores of any systems that will use third-party ACME clients to manage certificates from Trust Lifecycle Manager.

Below are basic instructions for how to meet these private trust requirements. For more details about how to install and manage the CA certificates in a local truststore, consult the documentation for your operating system version.

Note: These requirements only apply to private on-premises DigiCert ONE users. They do not apply to users of the cloud-hosted DigiCert ONE service.

Windows truststore requirements

To automate certificates on a Windows system via a private on-premises DigiCert ONE server, install the private DigiCert ONE certificate into the Windows truststore as described below.

Active Directory deployment

Refer to this page on the Microsoft website for instructions about how to distribute the DigiCert ONE certificate via Active Directory.

Standalone deployment

To install the DigiCert ONE certificate on a standalone Windows system:

  1. Copy the private DigiCert ONE certificate to the Windows system as a PEM-encoded file (.crt file extension). Note the certificate file location.

  2. Launch the Windows certlm.msc tool as an administrator to manage the certificates on the local machine.

  3. Use the Import action to browse and import the DigiCert ONE certificate file into the list of Trusted Root Certification Authorities > Certificates.

Linux truststore requirements

To automate certificates on a Linux system via a private on-premises DigiCert ONE server, install the private DigiCert ONE certificate into the Linux truststore as follows:

  1. Copy the private DigiCert ONE certificate to the Linux system as a PEM-encoded file (.crt file extension). Note the certificate file location.

  2. Make sure the Linux ca-certificates package is installed. Install it if needed, for example, by running apt-get install ca-certificates or yum install ca-certificates as root.

  3. Copy the .crt file for DigiCert ONE into the CA certificates directory. The location of this directory depends on your Linux distribution and version. See the table below for some possible locations.

  4. Run the command as root to update the local truststore based on the current CA certificate files. The name of this command depends on your Linux distribution and version. See the table below for some possibilities.
