    Automatic request type Select the automatic request type, either Regular or Wildcard.
    Certificate Authority

    Select one of the available local CAs configured on FortiAuthenticator from the dropdown menu.

    The CA must be valid and current. If it is not you will have to create or import a CA certificate before continuing. See Certificate authorities.

    Subject Information
      Subject input method Select the subject input method, either Fully distinguished name or Field-by-field.
      Subject DN

    If the subject input method is Fully distinguished name, enter the full distinguished name of the subject. There should be no spaces between attributes.

    Valid DN attributes are DC, C, ST, L, O, OU, CN, and emailAddress. They are case-sensitive.

      Name (CN)

    If the subject input method is Field-by-field, enter the subject name in the Name (CN) field (if the Automatic request type is set to Regular), and optionally enter the following fields:

    • Department (OU)
    • Company (O)
    • City (L)
    • State/Province (ST)
    • Country (C) (select from dropdown menu)
    • Email address
    Certificate Signing Options
      Validity period

    Select the amount of time before this certificate expires.

    Select Set length of time to enter a specific number of days, or select Set an expiry date and enter the specific date on which the certificate expires.

      Hash algorithm Select the hash algorithm from the dropdown menu, either SHA-256 (set by default) or SHA-1.
    Challenge Password
      Password creation Select to either set a random password, or use the default enrollment password (see Enrollment requests).
      Challenge password distribution

    Select the challenge password distribution method. This option is only available if Password creation is set to Set a random password.

    Renewal

    To allow renewals, select Allow renewal, then enter the number of days before the certificate expires (minimum of one day).

    When renewal is enabled, you can optionally either allow or reject SCEP renewal requests for expired and revoked certificates (as burst renewal requests from FortiGate devices could exhaust the FortiAuthenticator and create duplicate certificates), and either allow or reject SCEP renewal requests signed using the old private key.

    Subject Alternative Name

    SANs allow you to protect multiple host names with a single SSL certificate. SAN is part of the X.509 certificate standard.

    This section is not available when the certificate type is Intermediate CA certificate signing request (CSR).

      Email Enter the email address of a user to map to this certificate.
      User Principal Name (UPN) Enter the UPN used to find the user’s account in Microsoft Active Directory. This will map the certificate to this specific user. The UPN is unique for the Windows Server domain. This is a form of one-to-one mapping.

    Other Extensions

    Includes optional settings for SCEP enrollment requests.

     

    Add CRL Distribution Points extension

    Select to add a CRL Distribution Points extension.

    A fully qualified domain name (FQDN) must be configured. The FQDN can be added or configured by clicking Edit device FQDN.

  3. Optionally, apply key usage attributes.
    Advanced Options: Key Usages  
      Key Usages

    Key usage attributes identify the purpose(s) of a certificate's key. Some applications require the explicit presence of attributes before the certificate will be accepted for use. When an entity contains multiple certificates or keys, key usage attributes can also be used to identify which is the correct certificate or key to use.

    When the Critical option is enabled, the certificate can only be used for the purposes indicated by the selected attributes, and attempting to use the certificate for other purposes results in a CA policy violation.

    For detailed information about key usage attributes, see End entities.

      Extended Key Usages

    Extended Key Usages provides an extended list of selectable attributes.

    The Critical option can also be applied to extended key usage attributes. When the Critical option is applied to both key usage and extended key usage attributes, only certificates that are consistent with both fields are accepted.

    For detailed information about extended key usage attributes, see End entities

  4. Select OK to create the new certificate enrollment request.

    When created, the request will have a Status of Pending. A code is displayed which must be provided to the client as a challenge password for the automatic certificate enrollment process.
