From a root FortiGate IdP, you can edit each of the FortiGate SPs. For example, you can edit a FortiGate SP to generate a new prefix, or you can add or modify SAML attributes. When you generate a new prefix value, it is propagated to the respective downstream FortiGates.

- In the FortiGate Telemetry section, click Advanced Options. The SAML SSO pane opens.
- In the Service Providers table, select a device, and click Edit. The Edit Service Provider pane opens.
- Edit the settings as needed.
