[Freeipa-users] Cmd-line Unprovision & OTP setting for a host

Sat Dec 8 03:15:04 UTC 2012

Sorry for the extremely late reply, rebuilds of clients, keytab and
configuration primarily but certs too would be nice.

What we currently do during our provisioning process is disable the host
and reset the password (as previously mentioned) during the kickstart setup
process so the server can successfully enroll (or in the situation I'm
thinking of re-enroll) later on. The problem that causes is when you need
to log onto the server to reboot it but you've just removed your account.
So we have to use a shared local account to log on, limiting the need to do
things like that was the exact reason we installed IPA on our network in
the first place.

So if there was a command like ipa-client-backup or ipa-client-restore that
you could run to generate/restore a gpg file with your clients info we
could safely restore the config after disk had been wiped. Another possibly
simpler option would be being able to reset the OTP without having to
disable the host first, so the first time the IPA server sees a new
ipa-client-install request with the right OTP it automatically disables the
host server side then enrolls the client that made the request. (Or even
simpler if there's any documentation on what files you would need to back
up)

I prefer option 2 :-)

Thanks,
Charlie
