We are using ComponentSpace.SAML2 DLL libraries for SSO authentication in one of the MVC based WEB application.
Currently we are using One login(SSO) as IDP and we are planning to move to OKTA(SSO) as IDP.
For this purpose we are testing it first with OKTA after configuring required changes related to SP metadata and IDP metadata.
We are facing one issue while receiving and processing the SAML assertion contained in the SAML response from OKTA(IDP) after logging into the OKTA SSO portal.
We are getting below exception at this method :
Method: SAMLServiceProvider.ReceiveSSO(Request, out isInResponseTo, out partnerIdP, out loginUserEmail, out attributes, out targetUrl);
Exception type: SAMLBindingException
Exception message: The message is not an HTTP POST.
Please help us in tracking what will be the possible reason for this error.
Thanks & Regards,
