Reproducing the Issue
- Try to logon to your system.
- SSO Error received.
This means that the SAML response being sent back by the IDP is enveloped into <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" , which is not supported.
You need to check the configuration at the IDP to ensure the response is sent in plain way instead of SOAP envelope.
