After introducing the NGINx to my on-premise ADFS configuration (2 LB, 2 ADFS, 1 SQL server, 1 web server (claimapp*), and DC server), the authentication went fine from accessing the external URL of the website, then to the federation service page, entered
credentials, logged in, eventually to the Welcome page.
NGINx is on the DMZ zone
*claimapp is the test website page that I downloaded online for ADFS testing purposes.
However, i am not sure why the Welcome page doesn't display user name anymore. When I tested it all internally, the welcome page displays the username such as "Welcome <internaldomain>\<username>"
However, since I introduced the NGINx in with public facing URL and domain name, the authentication went through fine but the domain name and username doesn't show up on the Welcome page anymore.
Not sure if it is something in the code that I should look for troubleshooting this problem or it's somewhere else that I didn't update when switching to the public facing domain name.
Any idea would be greatly appreciated.
TIA!
