Reverse proxy from NGINX to Keycloak with 2FA

April 23, 2018 04:43AM
Hello all,

I have a problem with NGINX. In addition, I will provide you with a configuration file and a picture of the architecture schema ( https://ibb.co/jqvc8c ).

I want to access Keycloak via nginx and log in to it. I use it as an Identity Management where I have a login with a username and password and a certificate where I check the certificate, that is 2FA. My problem is that when I access the browser through NGINX, I do not get popup to submit my user certificate, but then go to the second step to enter a username and password, but after that, Keycloak tells me I'm missing a certificate.

Something I've tried and worked on is if I add these things to the configuration file, proxy_ssl_certificate and proxy_ssl_certificate_key will pass it on, but only for one user. An example if proxy_ssl_certificate and proxy_ssl_certificate_key are a certificate and a key from the user joncheski and log in to Keycloak with the user joncheski will pass successfully. But if I want to log in with another user, it will not pass, because the certificate and the username are not equal.
I need your help. How to set this up for more users to work.
