Words are cheap.
I've just came back from work, where I'm ironing out last twists of recent
classic migration.
One of them been that krb5.conf on one of the gateway systems posed itself as
an authoritative KDC for a parent domain. Whole segment of client systems went
upside down and hanged in that pose until I actually began to match every
config line by line.

Not necessary as long as the domain names can be resolved correctly.

That's enough.

NM is a network manager in its own rights. What you think about is
network-manager-gnome, most likely, and that is only a part of it.
Headless or not, NM can still be used to control networking connections.
So, Rowland's question wasn't all that useless.

1. Recheck the realm description in /etc/krb5.conf
2. Double check that date and timezone are set correctly.
`date -u` being the most trustworthy source.

You should, like, REALLY clean up your smb.conf. At least half of it is just a
garbage. And 'socket options' is literally a shot into your own leg.
