Hi Martin,

As far as I understood your description what you need is additional
authentication of web application sessions, rather than authentication
of individual TLS connections.

I guess you need a specialized reverse HTTP(S) proxy.  Stunnel is a
generic TCP/TLS proxy.  It has no understanding of HTTP and web
applications.

Best regards,
	Mike
