I am trying to configure SAML authentication for Zammad and I keep getting this fingerprint mismatch which does not make sense. I had compute the fingerprint using OpenSSL, both SHA1 and SHA256 and I'm still getting the fingerprint mismatch. I tried generated different certificates using SHA1 and SHA256 and computing respective fingerprints, still fingerprint error:
I, [2022-09-22T19:28:22.868683 #57117-109180] INFO -- : (saml) Callback phase initiated.
E, [2022-09-22T19:28:22.876176 #57117-109180] ERROR -- : (saml) Authentication failure! invalid_ticket: OneLogin::RubySaml::ValidationError, Fingerprint mismatch
Any idea what might be the problem? Can I turn on debug to see how the fingerprint is computed? I'm not Ruby savvy, so am not sure which knobs to turn.
