Use `openssl crl -text < FILE` to pretty-print a CRL.

Use `openssl ocsp` to perform an OCSP request:


openssl ocsp -resp_text \
  -CAfile /etc/ipa/ca.crt \
  -url http://$HOST:8080/ca/ocsp \
  -issuer /etc/ipa/ca.crt -serial $SERIAL_IN_DECIMAL

To be sure, also check that the issuer certificate and any other
certificates in the chain have not been revoked.

Let us know how you go.
