--- Comment #3 from nroach44 at gmail.com ---
Just performed a test using the /etc/pam.d/sudo file from debian.

Using buildroot's sudo file a password is prompted for, but it's always wrong

cat /etc/pam.d/sudo
auth        sufficient   pam_rootok.so
auth        required     pam_wheel.so use_uid
auth        required     pam_env.so
auth        required     pam_unix.so nullok

account     required     pam_unix.so

password    required     pam_unix.so nullok

session     required     pam_limits.so
session     required     pam_env.so
session     required     pam_unix.so
###

Using debian's sudo file a password is not prompted for and simply fails three
times:

cat /etc/pam.d/sudo
#%PAM-1.0

@include common-auth
@include common-account
@include common-session-noninteractive
###

[nroach44 at charon ~]$ sudo bash
Sorry, try again.
Sorry, try again.
sudo: 3 incorrect password attempts

The following shows in journalctl:

Jan 01 09:01:25 charon sudo[1094]: PAM (sudo) illegal module type: @include
Jan 01 09:01:25 charon sudo[1094]: PAM pam_parse: expecting return value;
[...common-auth]
Jan 01 09:01:25 charon sudo[1094]: PAM (sudo) no module name supplied

So it seems like the format is different for whatever reason.
