Splunk Cloud SAML SSO Signature Verification Failu...

Security

Hi Experts,

I'm trying to set up SAML SSO for Splunk Cloud against an external IDP.

I've loaded the IDP's SAML metadata into the Splunk SAML configuration. The metadata includes a self-signed signing certificate.

All the SAML authentication redirects are working, but Splunk complains that it could not verify the Assertion signature using the signing certificate.

What am I missing? Does Splunk Cloud not really support self-signed IDP signing certificates?
