Why is verification of SAML assertion using the IDP's certificate giving error"Failed to verify signature with cert"?

hi All,

We are migrating our AD provider to Azure AD, we generated the XML and cert file, and uploaded the XML via front end, its working for the login, but after validating, it lands on the below page, mentioning this error.

Verification of SAML assertion using the IDP's certificate provided failed. Error: failed to verify signature with certVerification of SAML assertion using the IDP's certificate provided failed. Error: failed to verify signature with cert

 In the authentication.conf i see the stanza getting updated with new entries, only 2 lines remain of the old config :
caCertFile = /opt/splunk/etc/auth/cacert.pem
clientCert = /opt/splunk/etc/auth/server_old.pem

I am not sure if client cert is being used at all, thinking something related to IDP chains, seeing other answers,

Not sure how to generate the certificate.

Cert generated from Azure has only one stanza, not 3 as described.

any leads would be helpful.
