SAMLv2 Error (v1.26.1)
-
I have managed to successfully set up SAMLv2 with Azure AD, however one of my clients is using Ping Federate and the integration is throwing a 500 error when reading the SAML response:
Unable to parse or validate SAML response.

After futher investigation, I asked the client to
- include the x509 certificate in their reponse
- sign the assertion
This fixed the issue. But still, it would be nice for Fusionauth to handle this a little more gracefully.

Hi @stuart-auld!
I am glad you got this sorted out!
Feel free to log an issue if you feel there is room for improvement based on this experience! That way our dev team can consider this in future iterations of FusionAuth.

Thanks!
Thanks,

Interesting, not sure how this would happen. Thanks for the report @stuart-auld - I agree, this is not a good dev experience. We will identify this cause and try to failure better.
