Thanks, but aren't some of these steps assuming that ipa-client has
been installed on the system? For instance, instead of "# ipa-join -s
ipa.example.com -b dc=example,dc=com -w Secret123", can't I instead
use kadmin to retrieve the keytab and then securely copy it over to
the client system? And, in the case of the ca.crt, if there if IPA
itself is not installed, the ca would not go to /etc/ipa/ca.crt, no? I
realize that I will lose functionality by not having ipa-client, but
just trying to build a case for supporting legacy systems that I would
never want to take the time to adapt ipa-client for.
