Openssl Error 20 Unable To Get Local Issuer Certificate
in iOS 6 Tutorial: Part 1/2. I created an AppID and SSL certificate and keys and PEM files in a local directory. Afterwards, I got to the step to test whether the certificate works, and I invoked the following command from this local directory: $ openssl s_client -connect gateway.sandbox.push.apple.com:2195 -cert PushChatCert.pem -key PushChatKey.pem This produced a lot of output. In the middle of the output was the following: verify error:num=20:unable to get local issuer certificate verify return:0 Is this an error, or is this a test for an error? If its an error, what would be the cause or what would you suggest to resolve it? Here is the complete output (less the certificate data): Enter pass phrase for PushChatKey.pem: CONNECTED(00000003) depth=1 /C=US/O=Entrust, Inc./OU=www.entrust.net/rpa is incorporated by reference/OU=(c) 2009 Entrust, Inc./CN=Entrust Certification Authority - L1C verify error:num=20:unable to get local issuer certificate verify return:0 --- Certificate chain 0 s:/C=US/ST=California/L=Cupertino/O=Apple Inc./OU=iTMS Engineering/CN=gateway.sandbox.push.apple.com i:/C=US/O=Entrust, Inc.

Maybe the CA isn't present. I then pulled the certificate from the output into a pem file and tried: openssl s_client -CAfile mycert.pem -connect the.server.edu:3269 And that didn't work either. What am I missing? Shouldn't that ALWAYS work? ssl openssl share|improve this question asked Jan 21 '11 at 22:24 Brian migrated from superuser.com Jan 22 '11 at 3:14 This question came from our site for computer enthusiasts and power users. For clarity sake, it appears that LDAPS, when served from Windows, does not present the CA certificate when a connection is made. Therefore, you should obtain the CA X.509 cert, export as base64 and assign as described in answers below. In my case, using python-ldap you assign it at GLOBAL scope (not your ldap.initialize() instance) as: ldap.set_option(ldap.OPT_X_TLS_CACERTFILE,'./ca_issuer_cert.pem') After this, I was able to use STARTTLS (within LDAP port 389) as expected. –mbrownnyc J

This should be straightforward - and it is - but Apple have found a way to make it trickier.Normal *nix SystemsOn unable to a normal unix system, openssl is pretty good at locating the root certificates, but it still doesn’t automatically reference them.
