SCEP

The FortiAuthenticator device contains a SCEP server that can sign user CSRs, and distribute CRLs and CA certificates. To use SCEP, you must:

Enable HTTP administrative access on the interface connected to the Internet. See Interfaces.
Add the CA certificate for your certificate authority. See Certificate authorities.
Select the CA to use for SCEP. See Default CA.

Users can request a user certificate through online SCEP, found at https://<FortiAuthenticator IP Address>/cert/scep.

General

As administrator, you can allow the FortiAuthenticator unit to either automatically sign the user’s certificate or alert you about the request for signature.

To enable SCEP and configure general settings, go to Certificate Management > SCEP > General.

The following settings can be configured:

Enable SCEP	Select to enable SCEP.
Default CA	Select the default CA to use from the drop-down list.
Enrollment method	Select the enrollment method: Automatic: The certificate is pre-approved by the administrator. The administrator enters the certificate information on the FortiAuthenticator unit and gives the user a challenger password to use when submitting their request. Manual and Automatic: The user submits the CSR, the request shows up as pending on FortiAuthenticator unit, then the administrator manually approves the pending request. Optionally, enter an email address to send pending approval notifications to.
Default enrollment password	Enter the default enrollment password that will be used when not setting a random password.

Select OK to apply any changes you have made.

Enrollment requests

To view and manage certificate enrollment requests, go to Certificate Management > SCEP > Enrollment Requests.

The following information is available:

Delete	Delete the selected certificate enrollment request.
Approve/Reject	Approve or reject the selected certificate enrollment request.

To view the enrollment request details:

From the enrollment request list, select a request by clicking within its row. The Certificate Enrollment Request window opens.

If the client has lost their certificate and key, select Did the client lose his/her certificate and key?
Select Close to return to the enrollment request window.

To reset the enrollment request status:

From the Certificate Enrollment Request window, select Did the client lose his/her certificate and key? The Reset enrollment request status? window opens.

There are two methods to reset the enrollment request:

Manually remove the old enrollment request, revoke its certificate, then create a new enrollment request with exactly the same configuration and subject name as the old certificate.
Re-use the same enrollment request by resetting its status and then revoking the lost certificate.

To re-use the same enrollment request, select Yes, I’m sure. This is the recommended method of resolving the issue.
