Thank you for your answer
Let me give you more details. My client needs to have a single sign on between CRM and Tableau
CRM uses WS-Federation (saml 1.1) and Tableau uses SAML SSO (saml 2)
The problem if a user connects to CRM the relying party generate a token with a claim
<saml:Attribute AttributeName="username" AttributeNamespace="http://domain.com">
<saml:AttributeValue>Domain\User</saml:AttributeValue>
</saml:Attribute>
But Tableau expects
<Attribute Name="username">
<AttributeValue> Domain\User </AttributeValue>
</Attribute>
The problem is the AttributeNamespace=”http://domain.com” and in saml 1.1 the ClaimType is mandatory.
