Automatically Login Using Windows User Info

I have a web app that uses Keycloak to login and handle user permissions. It’s in a closed environment and everyone is on the same domain.

Current flow:
User logs in to windows.
User opens web browser and goes to the app’s URL. It redirects to Keycloak URL.
User logs in. It redirects them back to our web app.
They can get to work.

Desired flow:
User logs in to windows.
User opens web browser and goes to the app’s URL.
User is logged in automatically since we already know who is logged into Windows.
They can get to work.

Keycloak is currently set up to use Active Directory users, but I need them to log in automatically.

Is this possible? Also, I’m forced to use Keycloak 2.5.1 due to restrictions out of my control.

Thank you
