Issue

When using SAML to authenticate users automatically, and when logging in from Tableau Desktop, an empty "Sign in to SAML Identity Provider" screen is shown and the following error message might occur:

Unexpected error
Username or password incorrect

Browser login works as expected.

Environment

  • Tableau Server 8.2
  • Tableau Desktop 8.2
  • SAML identity provider with automatic login

Resolution

If current IdP is not form based, run the following commands to disable SAML for Tableau Desktop:
tabadmin stop
tabadmin set wgserver.authentication.desktop_nosaml true
tabadmin config
tabadmin start

Cause

Only form-based SAML IdP are supported by Tableau Desktop.
