Thank you for posting this in Microsoft Q&A.
I understand you are facing an issue with Azure Single Sign-On using SAML. Specifically, you are receiving an error message with the code IDX10214: Audience validation failed.
Can you please check audience and issuer values?
The Issuer
value, the Audience
value must exactly match one of the service principal names that represents the cloud service in Microsoft Entra ID. However, if the value of the Issuer
element is not a URI value, the Audience
value in the response is the Issuer
value prefixed with spn:

please refer this article: https://learn.microsoft.com/en-us/entra/identity-platform/single-sign-on-saml-protocol#audience
Hope this helps. Do let us know if you any further queries.
Thanks,
Navya.
