IssueWhen logging into Tableau Online using SAML with Shibboleth the following error might occur:
The sign-in was unsuccessful. Try again. If you continue to get this message, capture the status information below, and send it to Tableau Support.
The site is configured to use the "..." attribute as the username. Login failed because this is not included in the IdP Response. To fix this problem, the site admin must either choose the correct attribute or clear it to rely on the NameID.
