replacing the certificate everywhere

[hboetes]

I just replaced the certificate and noticed I have to manually replace the used certificate entry in the web interface, in the radius server, in the OpenVPNs. And since I forgot about the radius server the company couldn't use WLAN until I fixed that.

Wouldn't it be nice if you could simply designate one certificate as the default certificate and that after that all services that depend on it use the default certificate and get restarted if needs be?
