Tilte : SAML is returning Unknown Issuer when signature certificate is validated and without certificate validation the the assertion endpoint(ACS) redirection lead to Http 500
I am creating a request with the the signature certificate to the Okta Saml. The signature certificate type is ".pfx " at c# side code from where i am trying to connect to SAML. At OKTA end, I am not able to upload the certificate of “.pfx” type , so I have converted “.pfx” certificate to “.pem” type and uploaded the same. when I am validating the request by checking the checkbox “Validate SAML request with signature certificate” then it throw an error of unknown issuer. Attaching the screenshot for same.
if i uncheck this flag ( validate SAML request with signature certificates) , the redirection is happening to ACS endpoint but with http status code 500. Please guide me to resolve this issue.
