Hi,

My application uses NGINX as its web server and I am adding support for client certificate authentication. I have a requirement where after NGINX validates the client certificate and provides access to my application, I need to obtain the Subject field of the client certificate to parse certain certificate details from my application. Is there a way to obtain this information from the application level or does this information reside only on the NGINX layer? I tried using APIs like ngx_ssl_get_subject_dn from my application but that didn't work. Please provide some inputs or point me in the right direction if I'm missing something.

Thanks
