authentik configuration

To support the integration of FortiManager with authentik, you need to create an application/provider pair in authentik.

Create an application and provider in authentik

  1. Log in to authentik as an administrator and open the authentik Admin interface.
  2. Navigate to Applications > Applications and click Create with Provider to create an application and provider pair. (Alternatively you can first create a provider separately, then create the application and connect it with the provider.)
  • Application: provide a descriptive name, an optional group for the type of application, the policy engine mode, and optional UI settings.
  • Choose a Provider type: select SAML Provider as the provider type.
  • Configure the Provider: provide a name (or accept the auto-provided name), the authorization flow to use for this provider, and the following required configurations.
    • Set the ACS URL to https://fortimanager.company/saml/?acs.
    • Set the Issuer to https://authentik.company/application/saml/<application_slug>/sso/binding/redirect/.
    • Set the Service Provider Binding to Post.
  • Configure Bindings (optional): you can create a binding (policy, group, or user) to manage the listing and access to applications on a user's My applications page.
  1. Click Submit to save the new application and provider.

FortiManager Configuration

  1. Navigate to https://fortimanager.company/p/app/#!/sys/sso_settings and select SAML SSO Settings to configure SAML.
  2. Under Single Sign-On Mode, choose Service Provider (SP) to enable SAML authentication.
  3. Set the SP Address field to the FortiManager FQDN, fortimanager.company. This provides the URLs needed for configuration in authentik.
  4. Choose the Default Login Page as either Normal or Single Sign-On. Selecting Normal allows both local and SAML authentication, while Single Sign-On restricts login to SAML only.
  5. By default, FortiManager creates a new user if one does not exist. Set the Default Admin Profile to assign the desired permissions to new users. A no_permissions profile is created by default for this purpose.
  6. Set the IdP Type field to Custom.
  7. For the IdP Entity ID field, enter: https://authentik.company/application/saml/<application_slug>/sso/binding/redirect/
  8. Set the IdP Login URL to: https://authentik.company/application/saml/<application_slug>/sso/binding/redirect/
  9. Set the IdP Logout URL to: https://authentik.company/
  10. In the IdP Certificate field, import your authentik certificate (either self-signed or valid).

Configuration verification

To confirm that authentik is properly configured with FortiManager, log out and log back in via authentik.
