PAM authentication is generally good - it also provides stuff like sessions and
other access control (for instance with login limits and the like), which pure
shadow access does not.

Okay, so what happens is that without PAM support, your shell startup scripts
that would normally fetch the system locale are probably not executed. Which one
exactly beats me, but that's probably not too important. You really shouldn't
disable PAM authentication on Linux.

Instead, you can edit /etc/pam.d/sshd. Disable the common-auth include line.
That should make it impossible to login with passwords - but still allow setups
with OTP's for instance, if ChallengeResponseAuthentication is enabled in
sshd_config.

Great!

Also good, but that's been LXDE's problem really.

Even better. It might look bad in single application mode, as explained before.

Let's assume that still to be the case, though. I'm retitling the bug report as
such and will leave it open for the time being.
