Hi @Hari Nair , please review this document for details on this error.
"Azure AD wasn’t able to identify the SAML request within the URL parameters in the HTTP request. This can happen if the application is not using HTTP redirect binding when sending the SAML request to Azure AD."
Most often, the error is due to one of the following issues:
- Ensure that single-sign on is enabled on the application side.
- The application must support service provider-initiated single sign-on (sometimes known as SP-initiated SSO). When entering a sign-in URL for an application that only supports identity provider-initiated single sign-on can lead to a bounce back from the application without a SAML response.
- Verify that the sign-on URL is correctly configured.
Please let me know if you have any questions.
If this answer helped you please mark it as "Verified" so other users can reference it.
Thank you,
James
