I am wondering if there is any way I can configure Tableau so it all the AD users can access the portal using their domain credentials? Currently we have about 30 groups and 100+ users who are accessing the portal but we would like to open to the all the domain user can access it. We have Tableau Server Version: 10.1.0 (10100.16.1029.1829) 64-bit.
I think you're asking about adding users to Tableau Server, not the Tableau customer portal, correct?
If so, yes, you are able to do this, and this article should walk you through the steps needed. Please reply if you hit any snags.
Thanks for using Tableau!
