please find enclosed the requested logs

The CA installation fails because it finds an existing entry in "cn=LIX.POLYTECHNIQUE.FR IPA CA,cn=certificates,cn=ipa,cn=etc,dc=lix,dc=polytechnique,dc=fr". It really looks like your topology used to have a self-signed CA at one point.

If you look at this entry, does it correspond to a CA known to you?
You can extract the certificate using
ldapsearch -D "cn=directory\ manager" -W -b "cn=LIX.POLYTECHNIQUE.FR IPA CA,cn=certificates,cn=ipa,cn=etc,dc=lix,dc=polytechnique,dc=fr" -LLL -o ldif-wrap=no
which should show a value for cacertificate;binary:: <content>

Then create a pem file with the format
-----BEGIN CERTIFICATE-----
<here paste the content>
-----END CERTIFICATE-----
and execute: openssl x509 -noout -text -in <pemfile>

You mentioned in a previous email that the server was originally part of a cluster but got "extracted" out of it to run the tests. Did this set of servers have a self-signed IPA CA? In the logs we can see reference to 3 different CA certificates for "CN=Certificate Authority, O=LIX.POLYTECHNIQUE.FR" (self signed, issued in june, june and july 2016). It's really a confusing situation, as it's the subject that IPA CA would use by default but it could also be a completely different origin.

Thank you very much for your help

It was part of a cluster but it is removed for the tests

As I am not able to use CNRS2-Standard, I need to use a different CA
authority

Ok, so you went through the right path by using ipa-ca-install. Now we need to understand why the command failed.
Can you share /var/log/ipareplica-ca-install.log? We may also need /var/log/pki/pki-ca-spawn.$date and /var/log/dirsrv/slap-LIX-POLYTECHNIQUE-FR/errors and access.

I thought using IPA as a certificate authority was logical (and should
also be easier)
but I can be wrong :-(
