When site-SAML is enabled, the following error message might occur:  
Sign in failed.

Additionally, the following error will show in the samlservice log file: 
Unable to create SiteSAMLUserDetails
result not unique

  • Site SAML for Tableau Server


  • Ensure no other user account has an email address that matches the username of the user that cannot login (other than the user themselves).
  • If a second user has an email address that matches the username of the impacted user, change the second user's email address or delete their account.


The username entry is duplicated in the "site_saml_users" table of Tableau's internal repository.

Modifying a user's email should not modify their username in the site_saml_users table as this can cause duplicate username entries in the table, our team is aware and investigating this issue.
