Yes, the auth0 documentation is either out-of-date or for another use-case. My auth0 configuration for Tableau Online looks like this:
{
"mappings": {
"email": "username"
},
"createUpnClaim": false,
"passthroughClaimsWithNoMapping": false,
"mapUnknownClaimsAsIs": false,
"mapIdentities": false,
"signatureAlgorithm": "rsa-sha1",
"digestAlgorithm": "sha1",
"lifetimeInSeconds": 43200,
"signResponse": false,
"nameIdentifierFormat": "urn:oasis:names:tc:SAML:2.0:attrname-format:basic",
"nameIdentifierProbes": [
"http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name"
]
}
and the “Application Callback URL” looks like this:
https://sso.online.tableau.com/public/sp/SSO?alias=someuuid
Hope that helps,
