SCEP

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

l Enable HTTP administrative access on the interface connected to the Internet. See Interfaces on page 30. l Add the CA certificate for your certificate authority. See Certificate authorities on page 140. l Select the CA to use for SCEP. See Default CA on page 148.

Users can request a user certificate through online SCEP, found at http://<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: l  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. l  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.
