I'm looking for some guidance on how to investigate further the issue I have.
There's a web application (documentation web-site) on-prem that users should be able to access using a shared username and password providing them read-only permissions.
Application access link looks like this - http://servername.domain.com:81
Once accessed the browser redirects to something similar to:
Once loaded, I get a form with username/password fields and Logon button.
The goal to publish access the user through myapps portal.
How would I go about publishing such an app?
