Hi!
It's been long since i looked into this neat appliance, some years for sure.
What stopped me from using Zentyal for my home server was that I couldn't make the CA import and use certificates I already had.
My intention: I'd like to import a cert from CAcert or LetEncrypt in order to have the CA use it to sign everything else OR in order to be used in all SSL-ciphered services Zentyal provides.
Is this possible in the meantime, now that 5.1 has been released?
