Login Prompt When Embedding Tableau Server in portals


Login Prompt When Embedding Tableau Server in portals


When embedding the Tableau Server interface in a portal, accessing pages of Tableau Server, such as http://[tableau-server]/views returns a login prompt.


This is the same information from Tableau Technote but I am saving for reference as I faced the issues and solved with the steps.

Environment

  • Tableau Server
  • Trusted authentication

Resolution

Tableau's tach note says that this could be due to trusted authentication is for only single view but there could be scenarios in which the browser rejects the tableau URL due to security settings.
If the case is with security settings it requires to add tableau web servers to the trusted sites which is also called Whitelisting.

Also this tableau requires allow third party cookies setting to be enabled in the browser.

To resolve this issue, enable unrestricted tickets. However, before you complete the following steps, see the cautionary note below them.

Unrestricted tickets can be enabled by using the Command Prompt from Tableau bin directory, and using the following commands in the order listed.

  • tabadmin set wgserver.unrestricted_ticket true
  • tabadmin config
  • tabadmin restart

Caution: Although trusted ticket is good for accessing one particular view, unrestricted tickets create a normal user session when redeemed. This presents a risk in that, if a user can obtain a ticket for an administrator account, the ticket will give the user unrestricted access to the Tableau Server. With a standard trusted ticket, even administrators can access only views.

Cause

This issue occurs when Tableau Server is configured to use trusted authentication. By default, trusted authentication works for single views only.

Additional Information

When wgserver.unrestricted_ticket is set to true, it mimics a single sign-on (SSO) authentication. This allows a user to authenticate on Tableau Server through the trusted ticket process until the user logs out, or the session expires.

Adding “Apply” Button to A Filter Menu In Tableau

Adding An “Apply” Changes Button To A Filter Menu In Tableau Sometimes when a user is changing the options they want on a filter in Tableau, the chart updates as they change each option. This might not be the best user experience if they are changing many options and don’t want the dashboard to redraw the view until they have completed their selection. It is very simple to fix this – Tableau includes an “apply” changes option, which when enabled, means the dashboard won’t redraw to reflect the new filter choices until the user presses the “apply” button. Simply click the drop down arrow on the filter menu > go to “customize”, then click “show apply button”.

Using Special Characters in Tableau URL Parameters

Using Special Characters in Tableau URL Parameters When we try to use special characters in URL parameters, the URL parameter might not do anything, or an error might occur. The issue can be resolve by:  Use one of the following workarounds: Replace the special character with the URL encoding sequence for backslash (\) (%5c) followed by the URL encoding sequence for the special character. The backslash is needed to escape the special character. For example, the URL encoding sequence for backslash and comma (\,) is %5c%2c.  In the data source, separate comma-delimited field values into separate columns that can be filtered independently. In Tableau Desktop, use a calculated field to replace the special characters, such as commas or spaces, with hyphens (-). Cause The browser cannot parse the special characters used in the URL. Additional Information The error varies depending on the browser and special character being used. Networ...
