When users request access to a project on Tableau Server, an email gets sent from tableau.prod.alert@purdue.edu on that users behalf to create a ticket for that request. This request will look like the following:
[USER] is requesting access to "[PROJECT]"
That user needs to reach out to the project leader(s) for the project they are wanting access to. The project leaders can be seen using the following dashboard: https://tableau.it.purdue.edu/#/views/ProjectLeaders/ProjectLeaders
