I  doubt that PAM is used, but I don't know for sure.

The script which is provisioning the system does a mere debootstrap of the latest Debian stable, installs a few additional packages (notably openssh-server and nfs-kernel-sever) and patches some configuration files. The patches which get applied on the configuration files were written by me, they contained no PAM-related settings. Hence, I don't think it is used.

The SSH connections are initiated not using password entry, but by key-authentication, in case that is important.

No, I can't. It asks me for a password as well. Pressing Enter yields a "Authentication failure".
