Hello Stunnel maintainers, I try to use real certificates of my web server for stunnel. I combine private key, my site's cert, and ca-bundle into a pem file, and it works fine when the client doesn't verify any certificate. Then I specify CAfile which is the ca bundle file from my registrar, at client side and turn on verification and always get errors below, whatever level 2 or 3: Sep 15 14:53:28 y400 stunnel[11666]: LOG5[11]: Service [http-proxy3] connected remote server from 192.168.1.104:45746 Sep 15 14:53:28 y400 stunnel[11666]: LOG4[11]: CERT: Pre-verification error: unable to get issuer certificate Sep 15 14:53:28 y400 stunnel[11666]: LOG4[11]: Rejected by CERT at depth=2:
However, level 4 works. I want to prevent man-in-middle-attack, so can level 4 achieve that regarding to my current setup? Both server and client side use stunnel 5.17 which are fairly recent.
Are you sure the bundle has the entire certificate chain for the CA?
I usually use the CApath parameter. It requires each certificate in it's own file with the hashed name as explained in the howto.
Regards Jose
