Ouch. That would be rather disruptive I suppose. There is quite a lot of activity going to this
server, not to mention it's the primary ntp and dns server for the network.

Do you suppose this todo list will work ?

Firewall off the rest of the network, leaving the ipa server alone
Stop ntpd
Set date to 8th of January
Run the getcert resubmit command.
Change date back to correct date
Start ntpd
Remove the firewall rules


How many of the services is required to be restarted for the renewal to work after the date is
changed to the 7th?
