Description
PREEMPT_DYNAMIC Debian 6.1.90-1
Using nginx to terminate TLS connections for different domains
I have the following configuration, to server different domains with individual TLS configuration:
stream { map $ssl_preread_server_name $name { default server_one; two.example.org server_two; three.example.org server_three; } map $ssl_preread_server_name $authen_cert { default "/etc/nginx/public.cert"; two.example.org "None"; three.example.org "None"; } map $ssl_preread_server_name $svc { default "on"; two.example.org "off"; three.example.org "off"; } server { listen 127.0.0.1:3128 ssl; ssl_protocols TLSv1.2 TLSv1.3; ssl_certificate /etc/letsencrypt/live/$name/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/$name/privkey.pem; ssl_client_certificate $authen_cert ; ssl_verify_client $svc ; <==== error happens here proxy_pass 127.0.0.2:3128; } }
I receive the error-message: invalid value "$svc" in /etc/nginx/sites-enabled/default:27//.
So I can't use the associated configuration to ssl_client_certificate, which renders my configuration unusable for targets needing cert auth.
Unfortunately if-conditions do also not work here, even, when I can read in documentation, that if-conditions should be available in server blocks.

why is it named PREread, when it happens AFTER termination?
I thought, that it reacts on the SNI Hello, so that the right configurations for TLS Termination could be identified, based on the hostname
ssl_verify_client
does not support variables:https://nginx.org/en/docs/stream/ngx_stream_ssl_module.html#ssl_verify_client
And even if it did, ssl preread happens after ssl termination anyway, so you wouldn't be able to use
ssl_preread_server_name
at ssl phase.
