We have set up access to Tableau Server (9.0.4) to off-shore people to come through Aventail on their local machines. I am hearing there is no single sign on with Aventail and so users must log into the Tableau Server once validated through Aventail. They can get to the Tableau Server links - they then get prompted for credentials. Tableau Server is not taking the credentials. Is there something I need to do to allow Tableau Server access to people coming through Aventail? I can find nothing anywhere about this. I have had the users try putting the domain first before their nt id and still it does not work. Anybody have any suggestions?
