Thank you for your help and suggestions! Looks like there was a
problem in 8.2 but it is gone in 8.9. So this impacts Ubuntu 20.04
LTS. I can explore further if anyone has questions
I did a similar test, also on Ubuntu 20.04 with openssh-server
1:8.2p1-4ubuntu0.4
My main sshd_config has the following:
# egrep -v '^(#|$)' /etc/ssh/sshd_config
Include /etc/ssh/sshd_config.d/*.conf
PasswordAuthentication no
ChallengeResponseAuthentication no
UsePAM yes
X11Forwarding yes
PrintMotd no
AcceptEnv LANG LC_*
Subsystem sftp /usr/lib/openssh/sftp-server
As expected, password authentication is not offered.
(1) if I create /etc/ssh/sshd_config.d/brian.conf with
Match user brian
PasswordAuthentication yes
then this has no effect - attempting to login as 'brian' only offers
publickey.
(2) But if I add those two lines directly to the bottom of
/etc/ssh/sshd_config, then they *do* take effect.
(3) If I put those lines in /root/brian.conf and add
Include /root/*.conf
to the *end* of sshd_config, then has no effect - same as (1).
Regards,
Brian.
