Hello,
If you have servers available behind your SSO, you can use the rocker docker files to host shiny server on your network using Docker containers. Because our servers are behind SSO, I don't have to worry about having users log in, but with that said, all employees have access to my shiny app.

FYI, those containers are built on u be on ubuntu.
Thanks,
Alfredo
