You can change the js and gz file of Tableau
Thank you for the suggestion. Have you done something similar before, editing these files? Do you know if they would get overwritten with each upgrade? I assume that would be the case.
I was able to add a custom message on the login screen, but here are the issues with it:
1. We have AD authentication enabled on the server. So when you go to the url, it pops up the credentials screen. You never see tableau login screen. If you logout, you see it, or any time you are kicked out after initial login you’d see it.
2. This is a hack and as such it is unsupported behavior. Each time tableau server is upgraded, this will need to be re-added. The problem also is that with each version upgrade, they change behavior and file locations. v 8 was different than v 9.2 and v 9.3 and 10 is also very different.
