Verify Error:num=27:certificate Not Trusted
favorite 3 I can not verify the certificate by openssl openssl verify cert.pem Gets something like this: cert.pem: / C = PL / O = DATA error 20 at 0 depth lookup: unable to get local issuer certificate The same cert from the machine on Centos - verified correctly.

If I understood: - From the Debian done command: openssl verify -CAfile ca-bundle.crt cert.pem where: - Ca-bundle.crt - ROOT CA of the certificate issuer (Unizeto / Certum - Poland) - Cert.pem - certificate obtained from the issuer (Unizeto / Certum - Poland) The result - test performed on a Debian system: openssl verify -CAfile bundle.crt ca-cert.pem cert.pem: OK openssl verify cert.pem cert.pem: / C = PL / O = data... error 20 at 0 depth lookup: unable to get local issuer certificate How to do that without indicating ca-bundle.crt - my certificate has a status of OK? –0chi0 Oct 9 '14 at 19:38 You can also set and export t

I tried using this: openssl s_client -connect the.server.edu:3269 With the following result: verify error:num=20:unable to get local issuer certificate I thought, OK, well server's an old production server a few years old. Maybe the CA isn't present. I then pulled the certificate from the output into a pem file and http://serverfault.com/questions/225449/ssl-certificate-error-verify-errornum-20unable-to-get-local-issuer-certificat 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 Jan 15 '13 at 15:23 add a comment| 3 Answers 3 active oldest votes up vote 2 down vote That error is openssl's way of saying, "I can't follow the certificate chain to a trusted root". I just did the same command to my own AD servers and I get a full cert-chain, but the top certificate has that exact error. If you have the pub-key of the CA that signed the cert you can specify it with the -CAfile or -CApath options share|improve this answer answered Jan 22 '11 at 0:40 sysadmin1138♦ 99.6k14124253 Ok, thanks for the respo
