Yes, use the ngx_headers_more module's more_set_input_headers
directive or ngx_proxy module's proxy_set_header directive in your
auth server's proxy location.

http://wiki.nginx.org/NginxHttpProxyModule#proxy_set_header

BTW, by default, the main request's headers will be forwarded to your
subrequest destination locations. If that's not what you want, use the
proxy_pass_request_headers directive to disable that:

http://wiki.nginx.org/NginxHttpProxyModule#proxy_pass_request_headers

For now, setting subrequest headers from within Lua is not implemented
yet in ngx_lua. But it's on our TODO list :)
