To be clear, all IPA servers are masters, some just run more services
than others. It sounds like you have at least one CA available which
should be sufficient.

Ok. I guess the place to start is to get certs for Apache and 389-ds,
then we can see about using these new certs.

In the thread you showed that the IPA 389-ds doesn't have a Server-Cert
nickname. You'll want to do the same for /etc/httpd/alias before running
the following commands otherwise you could end up with non-functional
server.

These should get IPA certs for 389-ds and Apache. You'll need to edit
these commands to match your environment:

# ipa-getcert request -d /etc/httpd/alias -n Server-Cert -p
/etc/httpd/alias/pwdfile.txt -C /usr/lib64/ipa/certmonger/restart_httpd
-N CN=ipa.example.com -K HTTP/ipa.example....@example.com

# ipa-getcert request -d /etc/dirsrv/slapd-EXAMPLE-COM -n Server-Cert -p
/etc/dirsrv/slapd-EXAMPLE-COM/pwdfile.txt -C
'/usr/lib64/ipa/certmonger/restart_dirsrv EXAMPLE-COM' -N
CN=ipa.example.com -K ldap/ipa.example....@example.com

I'd do them one at a time and wait until the cert is issued and tracked.
This will restart both Apache and 389-ds but it shouldn't affect
operation because the certs won't be used yet.

You then need to get the old CA cert and put it into the right places.
Since it is already in the PKI-IPA NSS database let's fetch it from
there. For giggles you should probably save whatever the contents of
/etc/ipa/ca.crt are before-hand.

# certutil -L -d /etc/dirsrv/slapd-PKI-IPA -n 'IPADOMAIN.COM IPA CA' -a
> /etc/ipa/ca.crt

Now add that to the Apache and 389-ds databases:

# certutil -A -n 'IPADOMAIN.COM IPA CA' -d /etc/httpd/alias -t CT,C, -a
-i /etc/ipa/ca.crt
# certutil -A -n 'IPADOMAIN.COM IPA CA' -d /etc/dirsrv/slapd-EXAMPLE-COM
-t CT,, -a -i /etc/ipa/ca.crt

Next add it to /etc/pki/nssdb if it isn't already there:

# certutil -A -n 'IPA CA' -d /etc/pki/nssdb -t CT,C,C -a -i /etc/ipa/ca.crt

Next, verify that the newly issued certs are trusted:

# certutil -V -u V -n Server-Cert -d /etc/httpd/alias
# certutil -V -u V -n Server-Cert -d /etc/dirsrv/slapd-EXAMPLE-COM

Both should return:
certutil: certificate is valid

Next is to configure the services to use the new certs. I'd stop IPA to
do this: ipactl stop

Edit /etc/httpd/conf.d/nss.conf and change the NSSNickname to Server-Cert

Edit /etc/dirsrv/slapd-EXAMPLE-COM/dse.ldif and set nsSSLPersonalitySSL
to Server-Cert

Now try to start the world: ipactl start

Run a few commands:

# ipa user-show admin
# ipa cert-show 1

Both should work.

Assuming all has gone well to this point, copy /etc/ipa/ca.crt to
/usr/share/ipa/html/ca.crt

Finally run: ipa-ldap-updater --upgrade

This should load the new CA certificate into LDAP.

This has the potential to break a whole bunch of your clients. It is
probably enough to just copy over the new CA cert to the right
location(s) on the clients. The mechanics of this depend on the OS.

No, has nothing to do with the CA at all. The client doesn't have (or
trust) the CA that issued the LDAP server cert.
