The first step in setting up trusted authentication is to configure Tableau Server to recognize and trust requests from one or more web servers:
Open a command prompt as an administrator and navigate to your Tableau Server bin directory (for example, C:\Program Files (x86)\Tableau\Tableau Server\7.0\bin).
Next, type the following command:
tabadmin set wgserver.trusted_hosts "<Trusted IP Addresses>"
In the command above, <Trusted IP Addresses> should be a comma-separated list of the IP addresses of your web server(s). For example:
tabadmin set wgserver.trusted_hosts "192.168.1.101, 192.168.1.102, 192.168.1.103"
The comma separated list should be within quotes with one space after each comma. Host names are not allowed.
If you have one or more proxy servers between the machine that is creating the trusted ticket (step 2, above) and Tableau Server, you also need to add them as trusted gateways. See Configuring Tableau to Work with a Proxy Server for steps.
Finally, type the following command to restart the server:
tabadmin restart
Next, you need to configure your web server to receive tickets from Tableau Server.
