Environment

  • Tableau Server
  • OpenID Connect
  • KeyCloak

Resolution

Option 1:
Make sure the Client authentication in Keycloak is set to "client ID and secret". For more information, please refer to the third-party links below
2.1.14. Client authentication *
By default, there are three ways to authenticate the client: client ID and client secret, client authentication with signed JWT, or client authentication with signed JWT using client secret.

Option 2:
Make sure the vizportal.openid.client_authentication parameter is set to "client_secret_basic" (the Tableau default). For more information, please refer to Error 69: "Unable to Sign In".
  • tsm configuration set -k vizportal.openid.client_authentication -v client_secret_basic
  • tsm pending-changes apply

Cause

Tableau Server does not currently support a signed Json Web Token instead of a secret.
