Hostnames and Active Directory



Hey all (sorry for starting a new thread about this, just subscribed)...

I'd just like to pitch in and say that having a valid hostname is also
needed for joining an Active Directory or FreeIPA domain from within
Anaconda.

A kerberos computer account principal is created based on the hostname
(as in gethostname()) of the machine. The keytab of the machine will
contain the hostname too.

So in order to join a domain from the Anaconda UI, we have to have setup
a host name before the post install configuration. This means that (for
the AD/FreeIPA use case) it's sufficient to have the hostname in the
progress 'spoke', as Chris pointed out:

https://www.redhat.com/archives/anaconda-devel-list/2012-December/msg00071.html

We would theoretically block on prompting for a the hostname if joining
a domain.

Somewhat related: In the case of kickstart, we currently assume that the
admin has setup some sort of way to distribute unique host names (either
via DHCP or munging the kickstart files as they're served). Perhaps this
can be fine tuned in the future.

Cheers,

Stef
