Greetings;

Stunnel 4.56 running under Win 7 SP1 x86.

Recently, the owners of a server I regularly connect to updated their server certificate; the former had expired at the end of May.

As soon as that event occurred, I deleted the old certificate, then used the "save peer certificate" function of Stunnel to get the updated one.

However, the new certificate fails to verify, even with the verify = 4 option in Stunnel. The error message is similar to what I used to get when doing a verify = 3 with some certificates. The general error output of Stunnel is:

CERT: Verification error: unable to get local issuer certificate 2013.06.09 16:37:46 LOG4[608:2336]: Certificate check failed: depth=0

When I open the new certificate with:

openssl x509 -text -in certname.pem

and view the certificate details, I'm not seeing anything obvious. The certificate is within a valid date range, and contains the same basic elements as other certs I've viewed. The certificate appears to have been issued by Startcom LLC.

If I comment out the verify statement, I'm able to successfully negotiate an SSL connection with the server.

I realize that this may be more of an openssl issue than an issue with Stunnel. Nevertheless, I thought I'd start here and throw it out to the floor for comments.

Anyone have any ideas or have run into this issue?

Regards,

Thomas
