SP Init fails with POST not valid

Friends,

We use SiteMinder federation Services for SAML integrations.

I am trying to setup SP Initiated authentication with Tableu Server. Entities are created, partnership is enabled with  HTTP-POST binding. When user access service, they get redirected to IDP SSO Service via POST.

Header shows: POST /affwebservices/public/saml2sso HTTP/1.1

There is no Query String. POSTData shows relaystate and SAMLRequest parameter. Decoding SAMLRequest points to correct SPID and some other info.

 

SPS fails with a 403.

FWS log shows:
