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

Sat Jan 12 20:46:13 UTC 2013

Again apologies for the late reply, I've just discovered a new issue
regarding this but I'll answer the original question before asking a
new one. Yes being able to set the OTP without disabling the host is one of
the ways we could solve this problem and yes the longer we can keep a
server enrolled the better.

The reason why it would be hard to change the order to something similar to
what you described above is due to the batch nature of kickstarting
servers. Your new sequence "uninstall client, recreate the host and OTP on
the server side, re-install the client" effectively translates to "log on
to the client but don't do anything yet, log onto the provisioning server
and recreate the host and set the OTP, return to your client session
and reboot it thus starting the automated provisioning process" which
doesn't work very well when trying to provision multiple servers or
automating things.

The other option of being able to backup and restore the config in a clean
way is still a viable option as far as I'm concerned. I just thought the
OTP route would be easier to implement. I just noticed someone else asked a
similar question which prompted me to trawl back through my e-mails to find
this thread.

The other issue that affects automated provisioning is we have just
upgraded from IPA 2.1.3 to 2.2.0 and found that OTP password reuse has been
disabled. Is there any way around this as it has broken our automated build
process?

Regards,
Charlie
