For one my ISPConfig installations I've created SSL certificates with a passkey during setup. The host of that specific ISPConfig installion is a Xen host. My problem is that I can't reboot the server myself if necessary. My hosting provider has to type the passkey during startup of the server. So, I want to get rid of that. I want to recreate the SSL certificates, but I haven't got a clue where to look or where to start. For as far as I can see that's the solution for my problem.
You must regenerate ISPConfig's SSL cert like this: http://www.howtoforge.com/forums/showthread.php?t=121
