More OpenSSL

In this post, I stated that the errors, see below in red, were due to the linux server not trusting the TESTAuthority CA, which is true and false. It's true in the strictest sense of the word, it's false in the sense that unlike Windows, Linux does not have a central repository for certificates and thus the concept of a Linux server trusting a CA is not quite correct.

CONNECTED(00000003)
depth=0 C = US, ST = York, L = York, O = York, OU = York, CN = crmdevbox.dev.com
verify error:num=20:unable to get local issuer certificate
verify return:1
depth=0 C = US, ST = York, L = York, O = York, OU = York, CN = crmdevbox.dev.com
verify error:num=27:certificate not trusted
verify return:1
depth=0 C = US, ST = York, L = York, O = York, OU = York, CN = crmdevbox.dev.com
verify error:num=21:unable to verify the first certificate
verify return:1

Since Linux does not have a central certificate repository we need to pass the CA certificate file to openssl, which we can do with the following command (Note that there is a -CApath switch to pass a directory rather than a single file, in case you want to store multiple CAs in the same place.):

openssl s_client -CAfile testauth.cer -connect server.dev.com:443
