Hello.

I contact you because I have a problem of expired certificates on my IPA servers.

I'm still using IPA 3.0.0 for the moment.

Because of this, unfortunately, the commands ipa user-show etc.. does not work anymore. I wonder if IPA itself work well or not when we have this certificate problem ?

Anyway, I came back in time, to before the certificates expire :
###
service ntpd stop
date --set="2018-03-10 10:00:00"
###

And then I tried to renew these certificates with certmonger :
###
# ipa-getcert resubmit -i 20160321140609
Resubmitting "20160321140609" to "IPA".
# ipa-getcert resubmit -i 20160321140642
Resubmitting "20160321140642" to "IPA".
# ipa-getcert resubmit -i 20160321140750
Resubmitting "20160321140750" to "IPA".
###

But, it didn't change anything, the certificate are still expired :(.

I have the following error message in httpd log when I perform a resubmit.

The CA service is running :
###

I wonder what I could do ? Thank you in advance for your help.
