Hi Florence,
I previously tried option a) and failed(need to find out why later), but
I was able to successfully reinstall the server and the client with
option b), thanks a lot! So when it says "Installing Without a CA", it
means without a "embeded CA"(the IPA's own CA), is that right?
Another main problem comes up for option b): now I am going to install
the replica server(ipa2), if I do the same as I did before:
[root@ipa1 ~]# ipa-replica-prepare ipa2.example.com
<http://ipa2.example.com>
copy the gpg file from ipa1 to ipa2
[root@ipa2 ~]# ipa-replica-install
/var/lib/ipa/replica-info-ipa2.example.com.gpg
Then I believe the Apache on ipa2(the replica server) will use the
Verisign certificate with the same hostname(DN): ipa1.example.com
<http://ipa1.example.com>, NOT ipa2.example.com
<http://ipa2.example.com>, hence the users who visit
https://ipa2.example.com will experience security warning from the
browser, as expected...
What could be a solution for this?
Thanks again!

Thanks for the quick response Florence!
My goal is the use a 3rd party certificate(such as Verisign
cert) for
Web UI(company security requirement), in fact we are not
required to use
3rd party certificate for the LDAP server, but as I mentioned
earlier, I
couldn't make the new Verisign cert to work with the Web UI,
without
messing up the IPA function(after I updated the nss.conf to use
the new
cert in the /etc/httpd/alias db, the ipa_client_install failed).
So I
tried to follow the Redhat instruction, to see if I can get the
Verisign
cert installed at the most beginning, without using FreeIPA's
own/default certificate), but I got the CSR question.
I did install IPA without a CA, by following the instruction at
https://www.freeipa.org/page/Using_3rd_part_certificates_for_HTTP/LDAP
<https://www.freeipa.org/page/Using_3rd_part_certificates_for_HTTP/LDAP>,
but failed to restart HTTPD. When and how can I provide the
3rd-party
certificate? Could you please point me a document about the
detail?
Hi,
you need first to clarify if you want FreeIPA to act as a CA or not.
The setup will depend on this choice.
- option a) FreeIPA with an embedded CA:
you can install FreeIPA with a self-signed CA, then follow the
instructions at
https://www.freeipa.org/page/Using_3rd_part_certificates_for_HTTP/LDAP
<https://www.freeipa.org/page/Using_3rd_part_certificates_for_HTTP/LDAP>
in order to replace the WebUI certificate. Please note that there
were some bugs in ipa-server-certinstall, preventing httpd from
starting (Ticket #4786 [1]). The workaround is to manually update
nss.conf (as you did) and manually import the CA certificate into
/etc/pki/pki-tomcat/alias, for instance with
$ certutil -A -d /etc/pki/pki-tomcat/alias -i cacert.pem -n nickname
-t C,,
- option b) Free IPA without CA
the installation instructions are in Installing without a CA [2].
You will provide the certificate that will be used by both the LDAP
server and the WebUI in the command options.
You'd need either a separate certificate or one with multiple subject
alternative names, one for each master. I also imagine you'd need to
provide this certificate at replica preparation time if you've installed
without a CA.
Yes, that's right. You can use the command ipa-replica-prepare with the
options --dirsrv-cert-file / --dirsrv-pin and --http-cert-file /
--http-pin to provide the replica's certificate and key. They will be
embedded in the replica file and used during the replica installation.
