Bonjour,

Hi,


So far it doesn't look like there was an IPA embedded CA signed by the external intermediate CA. Can you check the HTTP and LDAP server certificates with certutil? I would like to check who issued them. Since it's IPA 4.6.8, the HTTP cert is stored in /etc/httpd/alias. Find its nickname with
# certutil -L -d /etc/httpd/alias/ | grep "u,u,u"
*Server-Cert*                                                  u,u,u

IPA3                                                         u,u,u


Then get the subject and issue from the certificate:
# certutil -L -d /etc/httpd/alias/ -n *Server-Cert* | egrep "Issuer:|Subject:"

        Issuer: "CN=CNRS2-Standard,O=CNRS,C=FR"
        Subject: "E=sys...@lix.polytechnique.fr,CN=ipa3.lix.polytechnique.fr,
            Issuer:


For the LDAP server, same steps but at a different location:
# certutil -L -d /etc/dirsrv/slapd-LIX-POLYTECHNIQUE-FR/ | grep "u,u,u"
*Server-Cert*          u,u,u

# certutil -L -d /etc/dirsrv/slapd-LIX-POLYTECHNIQUE-FR/ -n *Server-Cert* | egrep "Subject:|Issuer:"

        Issuer: "CN=CNRS2-Standard,O=CNRS,C=FR"
        Subject: "E=sys...@lix.polytechnique.fr,CN=ipa3.lix.polytechnique.fr,
            Issuer:


If the issuer is an external CA, it's likely that your IPA deployment was installed CA-less.

Sorry I did misunderstood external CA.
Now if I am right, I am using an external CA to get certs but this CA is not installed on the server

How can I install an internal CA in a CA-less server ?


The output of ipa config-show would also show if there was a server installed with a CA.


Sorry it is in french
