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 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,
