[certtest] OCSP validation of the SSL certificate for https://certtest.ripe.net is failing


in case you have problems connecting to https://certtest.ripe.net with
Firefox3, have a look at Preferences/Advanced/Encryption, Button Validation.
If you have the option "When an OCSP server connection fails, treat the
certificate as invalid" enabled, you will get the following error message
from Firefox:

Secure Connection Failed

An error occurred during a connection to certtest.ripe.net.

Invalid OCSP signing certificate in OCSP response.

(Error code: sec_error_ocsp_invalid_signing_cert)

As far as I can tell the OCSP servers at the registrar who issued the
certificate for certtest.ripe.net claims that the cert is unknown to him.
