Puppet CRL Time Errors

Puppet is much loved for it’s clear meaningful messages when something goes wrong, made even more delightful when you combine it with the lovely error messages thrown out by OpenSSL.

Warning: SSL_connect returned=1 errno=0 state=SSLv3 read server
certificate B: certificate verify failed: [CRL is not yet valid for
/CN=host.example.com]

This error indicates that the certificate is failing to validate since the clock between the node and the puppet master differs. In my case, the clock on the node was far behind the master due to a VirtualBox clock drift issue.

In this case, it was a simple case of re-syncing the clock to resolve the issue. However if the master had been generating certs with the clock far in the future, I would have needed to re-generate my node certificates entirely as the certs would also be incorrect.
