Re: [Openvpn-users] Delete certificates

Ok, I think I have actually misunderstood the revoke thing then. Correct me, if I am still wrong:

./revoke-full <certname>

a ctl.pem file is automatically created in /etc/openvpn/keys

in openvpn.conf, I add:

crl-verify <path>/crl.pem

Then when a revoked certificate connects, it is disallowed, right?

But... Doing so, I am not allowed to connect even with certificates not being revoked. I get a:

CRL: cannot read: ...... : Permission denied.

The file is there, tried to grant all access to the file, but no change...

OpenVPN runs on OpenBSD 4.1 as user nobody.

How to solve this?

Regards, Lars.

You don't need to delete the certificate, this is the whole point.
Just make OpenVPN use the CRL, and create a script that regular copy
the CRL into the location OpenVPN watches.
This way, when a revoked certificate tries to authenticate, it will fail.

I create certificates for OpenVPN with ./build-key-pass, I revoke them with

... but how do I delete them - I mean if I want to disallow a certian
certificate. I can probably delete the file, but it will still be in the
list. What is the right approach?
