I have some trouble with Nginx and Jenkins (Hudson). I am trying to use Nginx as Reverse Proxy for the Jenkins instance with HTTP Basic Authentication.

It works so far, but i have no idea how to pass the Header with the Authentication Username.

location / {
  auth_basic "Restricted";
  auth_basic_user_file /usr/share/nginx/.htpasswd;
  sendfile off;

  proxy_pass         http://192.168.178.102:8080;
  proxy_redirect     default;
  proxy_set_header   Host             $http_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-User $http_authorization; 
  proxy_max_temp_file_size 0;

  #this is the maximum upload size
  client_max_body_size       10m;
  client_body_buffer_size    128k;

  proxy_connect_timeout      90;
  proxy_send_timeout         90;
  proxy_read_timeout         90;             
  proxy_buffer_size          4k;
  proxy_buffers              4 32k;
  proxy_busy_buffers_size    64k;
  proxy_temp_file_write_size 64k;
}
