I cannot ssh with kerberos from a Samba AD DC, but I can ssh with
kerberos to a Samba AD DC.
The ssh client (devstation) has this in /etc/ssh/ssh_config
SendEnv LANG LC_*
# It's best to limit this option to only trusted hosts:
The ssh server (rpidc2) has this in /etc/ssh/sshd_config
There is just this in /etc/krb5.conf
default_realm = SAMDOM.EXAMPLE.COM
dns_lookup_realm = false
dns_lookup_kdc = true
This all leads to this:
rowland at devstation:~$ ssh -K rpidc2.samdom.example.com
Linux rpidc2 5.10.52-v7l+ #1440 SMP Tue Jul 27 09:55:21 BST 2021 armv7l
