Issue
After configuring Tableau for SAML authentication, users are unable to login, and the following error occurs:Unable to Sign In
User account not found
If the username value on the IdP side does not match the Tableau Server or Tableau Cloud username, consider one of the following options to align the values.
If a value on the IdP other than username matches the Tableau Server username.
For example, if the display name matches the Tableau Server username you can do one of the following:tsm authentication saml map-asssertions --user-name displaynameNote: This command is case sensitive, so be sure to specify the attribute name exactly as it is shown on the IdP. For example, if the IdP attribute is "DisplayName", use
DisplayName
and not displayname
in the TSM commanC:\Program Files\Tableau\Tableau Server\<version>\bin
and enter the following command:
tabadmin set wgserver.saml.idpattribute.username displayname
DisplayName
and not displayname
in the tabadmin set command.If there is no value on the IdP side that matches the Tableau Server or Tableau Cloud username, or it is not possible to make changes to the IdP.
