Issue/Introduction

When setting up SAML, we are getting error:

ERROR 2023-08-19 13:52:23,564 [http-nio-80-exec-6] filter.SAMLFilter (clarity:xxxxxxxxx:-1:none) Error occurred authenticating with SAMLFilter
java.lang.RuntimeException: Unauthenticated SAML response received: XXXXXXXXXXXX is not a valid audience for this Response

Environment

Release : Any

Resolution

1. The EntityID in Clarity SAML Configs is not matching the EntityID in the IDP settings. 
2. Please check both and ensure both are set to something as follows:
   https://<Servername>/niku/nu#action:union.samlMetadata
3. Restart is not typically required, test again
