[oe] [Yocto 1.6] PAM _pam_load_conf_file: unable to open /etc/pam.d/system-auth

[Kevyn-Alexandre Paré]

Hi,

Just trying to found what's missing for PAM to work so ssh will stop
exiting with Broken pipe? Quick fix to solve ssh broken pipe is to
change in /etc/ssh/sshd_config "UsePAM yes" to "UsePAM no". But this
does not remove my PAM error?

Here the log for PAM:
root at ka:~$  journalctl | grep -i PAM
Jan 01 00:00:11 ka systemd[1]: systemd 211 running in system mode.
(+PAM +LIBWRAP -AUDIT -SELINUX +IMA +SYSVINIT -LIBCRYPTSETUP -GCRYPT
+ACL +XZ -SECCOMP -APPARMOR)

/lib/systemd/systemd: Operation not permitted

So my image contain pam:
bitbake -e nirs-console-image | grep ^DISTRO_FEATURES=

                                libc-posix-wchar-io largefile opengl
ptest multiarch wayland pulseaudio systemd pam"

Any clue or advise on how to fix this and why it's not working?

BR,
