allowing guests in via ssh

I recently setup a demo machine for a presentation on pxe boot, where I wanted people to be able to login and have a look around a demo pxe boot VM.

Lots of ways to do this, but the way I wanted to make this work was via ssh, without requesting a password.

To do this, I configured sshd with:

UsePAM yes
PermitEmptyPasswords yes

and configured /etc/pam/sshd, to allow members of the demo group access, by adding the following line:

auth sufficient user ingroup demo

then I just add users, and put them in the demo group if I want them to login without a password.. neat.
