tableau_trusted_authentication_api

Introduction

This work is to simplify the Trusted Authentication work for Tableau Server by Node.js.

What's Tableau ? Tableau is one of well known Business Intelligence Tools.
More Info

Trusted Authentication is a Single-Sign-On method for user to retrieve views (so call viz) from Tableau Server to a Web Server using HTTP/HTTPS protocols. No matter your Web Server is built by which programming languages, as long as the program can use HTTP/HTTPS protocols you can do Trusted Authentication. In this case I use Node.js.

Begin works

First, you need to have a Tableau Server, then make some configurations on Tableau Server side. eg: tell Tableau Server to trusted your Web Server ...etc, you can either use TSM CLI or TSM web interface.

tsm authentication trusted configure -th "<trusted IP addresses or host names>"
tsm pending-changes apply

References about this setup.

Additionally, there is one thing to know, Tableau Trsuted Authentication has a default restriction, which is :

• if using this way to implement Single-Sign-On, user can only access views only. If you want to access whole Tableau Server resources, use tsm configuration set to disable this restriction as follows :

This step is optional and not recommended!

tsm configuration set --key wgserver.unrestricted_ticket --value true
tsm pending-changes apply
