First and foremost, this is unsupported and will revert back to default upon upgrading or reinstalling. If stuff breaks, you're on your own so take a backup first!

Following my previous posts, Customizing the Tableau Server Login Screen, I have seen some admins wanting to allow the users in their company to automatically add themselves to Tableau Server upon first login (as opposed to pre-adding an AD group). Below I have added a simple web form to the login screen to get the user's information to add to Tableau Server via REST API.

The form will then call a PHP script I have running on a web server which takes the username that the user enters and adds it to Tableau Server via REST API and then sends the user back to this login page. Here's a few notes though:

- Unless you have a core license, users may quickly take up your interactor licenses.

- Instead of directly adding users, you can make the form send an email to yourself with the user's info to request access.

- This works great with Active Directory authentication. However, with Local Authentication, the version 8 REST API does not include a way to set the user's password (this can be accomplished in version 9 though).

- If you have AD auth and automatic logon enabled, this will be seemless for the user.

Let me know if there are any questions! Admin away!
