IDP Initiated SSO login is not working

I have okta as identity provider as Okta and using Keycloak as Identity broker between IdP and my application.

I have done SP initiated flow to get authcode to my app which is working fine.( I created saml identity provider, OIDC client in keycloak and app in Okta). I have also tried some configuration to achieve IDP initiated sso login as per the given documentation but got no success.

Please suggest correct working configuration to achieve IDP initiated sso login in keycloak.

Try the guide here Keycloak with Okta IDP Initiated SSO Login | Lisenet.com :: Linux | Security | Networking

It’s complicated, but it’s the best guide I’ve found for setting up IdP-initiated that I’ve found.
