Tableau Views do not load for some users in Lightning Web Connector embed in Salesforce

Publish Date: Jun 3, 2026
Description

Customers may experience a partial authentication failure when using the Tableau Lightning Web Component with seamless authentication in Salesforce. In environments where users authenticate to Tableau via UPN (User Principal Name) — common in Microsoft Entra-federated setups — the LWC's default field mapping may pass the user's email address instead of their UPN. When a user's email address and UPN are the same, authentication succeeds. When they differ, that user cannot access Tableau content through the LWC.

This produces a situation where some users see Tableau content normally while others receive authentication errors or a blank view, with no apparent pattern from the end user's perspective. The issue is environmental and configuration-based, not a product defect.

Key conditions:
- Tableau is embedded via the standard Tableau Pulse Lightning Web Component
- UPN and email address are not identical for all users in the IdP

Resolution

1. Have the Salesforce Admin identify the Salesforce user record field that contains the value matching each user's Tableau username. In UPN-based setups, this is typically a dedicated UPN field on the User object — confirm with the IdP/directory team which field holds the exact string Tableau expects.

2. In Salesforce, navigate to the page or app builder where the Tableau Pulse LWC is configured.

3. Open the LWC component properties. Locate the field used for username mapping passed to Tableau for seamless auth. Change this to the field identified in step 1 (e.g., a custom UPN field rather than the standard Email field).

4. Save the configuration. Test with a user whose UPN and email address differ — they should now authenticate and see Tableau content successfully.

5. If a custom UPN field does not yet exist on the Salesforce User object, work with the Salesforce admin to create one and populate it via the IdP sync or user provisioning process before remapping.
