Thank you for the details.
Could you please go through the below details and provide your thoughts.
1. Our system is acting as Identity Provider.
2. Vendor system is acting as Service Provider.
As we are acting as Identity Provider, I have configured the below details in the federation partnership
1. Navigated to a partnership
2. Navigated to SSO and SLO section
3. Configured the below details within IDP Discovery section
Enable IDP Discovery : Yes
Service URL: https://idpsystem.dev.com/affwebservices/public/saml2ipd
Common Domain: .dev.com
I have referred the below CA Docs and made the configuration changes at IDP end
IDP Discovery Profile (SAML 2.0) - CA Single Sign-On - 12.7 - CA Technologies Documentation
Can you please confirm if we need to make further any changes at IDP end ?
Thank you again for your help.
Thanks & Regards,
Gopi.
