Hi,
If I am using Oauth authentication for consuming the views by ODBC connections, I would check if Oauth Authentication is enabled at server level in Administration ->Server Configuration-> [Server Authentication](https://community.denodo.com/docs/html/browse/8.0/en/vdp/administration/server_configuration/server_authentication/server_authentication) section.
For consuming views from Denodo in Power BI using Single Sign On, Kerberos and basic authentication methods are supported. SAML authentication for consuming the Denodo REST services is not supported at this moment.
For further information about the custom connectors and the authentication methods, please refer to [Connecting Power BI](https://community.denodo.com/kb/en/view/document/How%20to%20connect%20to%20Denodo%20from%20Power%20BI) and [Denodo Power BI Custom Connector](https://community.denodo.com/docs/html/document/denodoconnects/8.0/en/Denodo%20Power%20BI%20Custom%20Connector%20-%20User%20Manual#:~:text=and%20Basic.-,Windows%20authentication,-When%20you%20decide) User Manual which explains the steps to connect Power BI with Denodo.
If you still need further assistance and if you are a valid support user, you can raise a [Support Case](https://support.denodo.com/cases/add), for further assistance from the Support Team.
Hope this helps!
