[keycloak-user] Redirection issue with proxy behind keycloak

[Scott Rossillo]

What are you using as your proxy?

Spring Security needs to know it’s behind a proxy when generating login redirects.

If Nginx, set:

proxy_pass http://your-upstream-here;
proxy_http_version 1.1;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto https; # <- only set this if you’re using SSL

The adapter creates a `/login` endpoint in each of the services which redirects to the keycloak login page and then redirects back to the service when authentication is done. I also have a proxy service which I want to publish in the 80 port and will take care of routing all the requests to each service. The proxy performs a plain FORWARD to the service, but the problem comes when I securize the service with the keycloak adapter.

When keycloak sends the redirection, the url shown in the browser is the one from the service and not the one from the proxy. Do I have some choice to tell the adapter I want to redirect back to the first requested url?
