dansmith, It's my understanding that verify = 4 should, theoretically, look only for the server certificate, and this is the way I've been using it with great success over the past year or so. Recently, however, I ran into an exception to that behavior. In my case, I only had to download and install one certificate; that of the signing CA. I simply pasted it directly below the server certificate in the associated .pem file. The CA certificate wasn't originally in .pem format, so I converted it beforehand. OpenSSL has conversion capability, and there are also online certificate tools available. Your mileage may vary. Good luck. Thomas On 7/8/2013 3:01 PM, dansmith wrote:
Could you kindly break it down for me. Are you saying that I need to have two CAs A & B. A signs the certificate of B and B signs the certificate of my server? Do I understand correctly that verify=4 is supposed to simply ignore any CAs and only look at the actual certificate, comparing it to the certificate in CAfile ?

You're not missing anything. I've experienced a similar issue. While verify = 4 generally works well in most cases and will ignore the CA chain, I've encountered a few isolated incidences in which I've had to append or "chain" the server certificate with the certificate of the CA. Give it a shot and see if it resolves your issue.

I would expect that level 4 only compares locally installed certificates, however I get the same behaviour as with level 3, stunnel expects a CA cert. Here'e the relevant log when on level 4

What am I missing in understanding verify's level 4 ?
