When configuring a new application in the IDSP Admin Console, the system currently requires a certificate to be imported for the access gateway/client type. You have requested a way to create applications without mandatory certificate binding to simplify the onboarding process.
Siteminder integration with IDSP requires "Trusted" client types, which enforce certificate-based authentication (Client Assertion) for secure token exchanges.
The requirement to use a certificate is governed by the Client Type and Authentication Method selected during application creation.
Note: The request to eliminate the cert configuration for trusted clients is currently tracked as an enhancement request and will be reviewed for some future release.
