Environment

  • Tableau Server 
  • SAML

Resolution

It is possible to continue the sign in but an update should occur to complete the configuration in the IdP so that the request (AuthnRequest) is sent as https not http.

Please refer to your IdP vendor help page for specific configuration instructions.

 

Cause

Tableau Server sends a SAML request (AuthnRequest) as http to the IdP instead of https.  The request was judged by the browser to be insecure because it is an http request.
