debug log error
Unable to do sso or federation. com.sun.identity.saml2.common.SAML2Exception: Provider's signing certificate alias is missing.


your IDP is missing certificate that is required by server to sign SAMLrequest.

solution:
configure idp with x509 certificate
reconfigure idp with pre-configure "Signing Key"(option you will get when configuring IDP)
