[keycloak-user] Issue Configuring HTTP Reverse Proxy to Keycloak

Hello, I am having trouble getting keycloak to work behind a reverse proxy. I have installed Keycloak on the same server as our existing web application running in Tomcat, with keycloak listening on 8081 and Tomcat listening on 8080. I have configured an HTTP reverse proxy in Tomcat using https://github.com/mitre/HTTP-Proxy-Servlet. I am forwarding /auth to the reverse proxy, which in turns connects to keycloak ( http://localhost:8081/auth). When I visit "http://localhost:8080/auth", the first page in this scenario works: the "Welcome to Keycloak" page appears. But when I click on the "Administration Console" link, the first redirect works, to "/auth/admin/master/console". But it then quickly redirects the browser directly to the keycloak port: http://localhost:*8081*/auth/realms/master/protocol/openid- connect/auth?client_id=security-admin-console&redirect_uri=http%3A%2F% 2Flocalhost%3A8080%2Fauth%2Fadmin%2Fmaster%2Fconsole%2F& state=a36dd30e-6268-4545-9a4f-a397169917b6&nonce=79d7099d- 10df-471f-96e9-b13a8da17b55&response_mode=fragment&response_type=code&scope= openid The reverse proxy sets the X-Forwarded-For and X-Forwarded-Proto headers. And I have configured keycloak according to https://keycloak.gitbooks. io/server-installation-and-configuration/content/topics/ clustering/load-balancer.html, setting the proxy-address-forwarding attribute. I am also seeing, on the final redirected page, the error "Invalid parameter: redirect_uri". Any help would be very appreciated. -- *Colin Ritchie **|* *Engineering Manager* *|* *Tasktop Technologies*
