We have a certificate authority with Freeipa and I try to put in place a subordinate CA with Freeipa too.
I started the installation of the subordinate CA with the
ipa-server-install --external-ca command. The result is an ipa.csr file.
The Freeipa documentation says I have to have the certificate signed by the root CA:
This will generate a CSR in /root/ipa.csr. This is the file you need to provide to your CA for signing. You will also need to obtain a PEM copy of your CA trust chain.
Once you have both of these you can continue the installer
But there is no details.
ipa-getcert request command tells Certmonger to generate a signing request and to submit the request to for signing to a CA.
I would like just to sign the CSR by the root CA (because I already have the CSR automatically generated during the installation). How to do that please?
Thank you a lot!
