Hi,

Currently we have a setup where Okta acts as SP and redirects user to external IdP for authentication. During SP initiated flow, Okta generates a SAML Authn request (which is signed using Okta certificate, i.e self signed) to external IdP

Now we have an urgent ask from customer to sign SAML Authn request using third party CA cert , not using Okta certificate. I referred the following article - https://developer.okta.com/docs/guides/sign-your-own-saml-csr/overview/

Since Okta acts as SP i am following steps related to SAML inbound request. Below screenshot gives us information for uploading third party CA signed cert to SAML applications on-boarded as SP within Okta and doesn't provides steps to upload cert for Identity Provider

They have simply specified "For Inbound SAML, follow the existing procedures for your setup". Can someone please help me by elaborating those steps?
