Based on the provided context, it seems like you’re encountering a SAML WebSSO request processing issue. This could be due to a variety of reasons, such as incorrect configuration or issues with the SAML2 Authentication response protocol. In terms of checking the configuration, Pega doesn’t store this information in a specific table. Instead, it’s stored as instances of the Data-Admin-AuthService class. You can check these instances for any discrepancies in your configuration. If the issue persists, it might be beneficial to compare the configuration of the working authentication service with the one that’s not working to identify any differences.
