As I recently posted in another thread, I just migrated my SME 9 installation to a virtual machine under Proxmox 4 by doing console backup, new install, console restore, yum update, and then reinstalling my contribs. Two of those contribs were openvpn-bridge and phpki.
Since then, I've been getting an email periodically stating that "CRL update failed". Google led me to the wiki page for openvpn-bridge, and that suggested phpki. When I went to the certificate management page on my server, I found that phpki does not appear to be configured--it's asking me to create a new CA.
...and as I was writing this, I read through the rest of the wiki page on phpki, and found this section:
http://wiki.contribs.org/PHPki#Re-install. It looks like I need the old config.php file, which isn't part of the backup and apparently isn't templated. Fortunately, my original drives are still available and haven't been altered. But before I hook one of them up to start pulling data off it, what else wasn't backed up that I will need to get phpki working again? Should I just copy the whole /opt/phpki directory?
