Hi Jan,

I'm grateful for your help. I've researched how to follow your
recommendations above, but I'm not having a lot of luck. According to
old posts in this mailing list,
https://www.redhat.com/archives/freeipa-users/2013-May/msg00199.html,
the command ipa-server-certinstall is the way to go. That said, I
found an issue you've filed to allow for this, and it was implemented
in FreeIPA 3.3: https://fedorahosted.org/freeipa/ticket/3641
Unfortunately, this system is running FreeIPA 3.0:

# rpm -qa | grep -P "ipa[_-]"
ipa-pki-common-theme-9.0.3-7.el6.noarch
ipa-server-selinux-3.0.0-26.el6_4.4.x86_64
ipa-pki-ca-theme-9.0.3-7.el6.noarch
ipa-client-3.0.0-26.el6_4.4.x86_64
ipa-admintools-3.0.0-26.el6_4.4.x86_64
libipa_hbac-1.9.2-82.10.el6_4.x86_64
libipa_hbac-python-1.9.2-82.10.el6_4.x86_64
ipa-python-3.0.0-26.el6_4.4.x86_64
ipa-server-3.0.0-26.el6_4.4.x86_64
#

I've found these instructions:
http://www.freeipa.org/page/Howto/CA_Certificate_Renewal. I've read
those instructions, and I believe I may have a misconception about
this process. The procedure calls to:
# cp /root/ipa.crt /usr/share/ipa/html/ca.crt
# cp /root/ipa.crt /etc/ipa/ca.crt

Can you clear up what /root/ipa.crt ought to contain? I assume it
ought to contain *only* the root CA certificate which is the *first*
key in the bundle provided by the 3rd party Certificate Authority. Is
that correct?

The files /etc/ip/ca.crt already exists, but it is a single
certificate. The file I have, issued alongside with the certificate by
GoDaddy, is a CA bundle. It contains 3 public keys in sequence in a
single file. Could you please be more detailed as to how to accomplish
this: "you need to import the CA certificate to NSS databases at
/etc/dirsrv/slapd-DIRSRV_REDACTED, /etc/httpd/alias and
/etc/pki/nssdb, copy it to /etc/ipa/ca.crt and
/usr/share/ipa/html/ca.crt and update
cn=CAcert,cn=ipa,cn=etc,dc=example,dc=com in LDAP with it."

I certainly hope these are not inappropriate questions: I'd just like
to ensure this is done correctly. Thank you.
