Cause

Currently, there can only be one certificate in the SAML2 keystore referenced from the saml2.properties file.

When listing the keystore you should only see one key pair.

 

Environment

CA Performance Mangement

Resolution

Make sure the SAML keystore only contains the one key pair.

The root and any intermediates are imported into the Java cacerts keystore per the documentation
