      Hi jimp,

      bad news :(

      I did a complete fresh installation of pfsense and I am on 2.0-RC3 (amd64) built on Sun Jul 3 04:02:48 EDT 2011

      I created a new CA, created 2 certs (server + client) and configured a new OpenVPN server. I just can connect if I do not select any CRL in the OpenVPN Server configuration.

      I opened an other thread on friday because I didn't remember this thread. Perhaps this will help you a little bit to resolve this error.
      http://forum.pfsense.org/index.php/topic,38466.0.html

      Thanks for your help!

        So if you revoke a certificate on the CRL, does it work? Does it still just not like an empty CRL? (Well, it's a valid CRL, just doesn't have any certificates revoked in it)

          I know what you mean - and - you are right.
          I created a new certificate and revoked it - so the CRL isn't empty anymore.
          An now I can connect with an other certificate which isn't revoked.

            What if you then remove that certificate from the CRL so it's "empty" again?

              Sorry for my late reply.

              I created a new OpenVPN server, server cert, two user certs. One for use and one for putting into the crl.
              First try with the default empty CRL: FAILED
              second try with a revoked cert in the CRL: WORKED
              third try with cancelling the revocation and an empty CRL again: WORKED

                I have also tested with an empty CRL today, and the OpenVPN entity stopped. I have not tested with entries in CRL.

                  Is the CRL file it mentions empty (zero bytes) when it fails, or does it have something in it?

                    Yes, it seems to be 0 byte:

                    -rw–-----  1 root  wheel    0 Jul 13 16:27 server1.crl-verify
                    -rw-------  1 root  wheel    0 Jul 13 09:04 server2.crl-verify

                      That would be the problem then.

                      I thought I had committed a fix for that before, I'll have to look into it again. Might be a couple days though.

                        Try it with these changes:

                        https://github.com/bsdperimeter/pfsense/commit/2ce206b048e8496e84f732556219e18290c5481c

                        (Or wait for a snapshot that includes those changes)

                          Thanks jimp,
                          the CRL is no longer empty, and works as expected.

                            Did you try this with a new created CRL which has no certificates revoked in it ? (You remember, creating CRL, revoke a cert, cancel the revocation and then testing?)

                            I am at home for some days now and it wouldn't be fine, if I crash my OpenVPN and could not access the machine anymore untill I am back at work ;-)

                              I did, and the CRL is no longer empty even when it has no certificates in it.

                                Hi,

                                I am using amd64 snapshot from 15 july.

                                I know there were some fixes before this snapshot. I created a cert some days before this snapshot called "test". I revoked it with the according CRL and it worked. No I wanted to cancel the revocation and wanted to delete the Cert "test" from the according CRL. It couldn't be deleted. It still exists there if I am deleteing it from "certificates".

                                If I create a new cert with same CA and same CN called "test" it appears again and as revoked. Then I am still not able to delete this cert from the CRL.

                                  So you click the "x" on the CRL view, and what happens? Nothing? An error? Something else?

                                    There comes a question if I would like to delete the cert from the CRL. I click OK. Then the cert disappears from the list. If I click again on the "Certificate revocation" tab, then the cert is again in the crl.

                                    No visible error message.

                                      Should be OK now, I just pushed a fix.

                                        Hi,

                                        I did some tests with 2.0-RC3 (amd64) built on Thu Jul 28 05:40:09 EDT 2011.

                                        Deleting revoked certs of a CRL is working now as expected.
                                        Allow and deny access is working as it should. I tested it several times with revoking a cert and then deleting the revocation.

                                        Thanks jimp!
