Comment 26 for bug 1644428

Not sure if this should be a new bug, opening a zesty task for now until we are sure.
Summary: pam_winbind.so fails to open
Related: bug 1584485
Repro:
 $ apt-get install samba winbind libnss-winbind libpam-winbind
 $ sed -i -e 's/^passwd: compat/passwd: winbind compat/' /etc/nsswitch.conf
 $ systemctl restart smbd nmbd winbind
 $ tail -n 5 /var/log/auth.log

May 5 06:32:08 zesty-test sudo: PAM unable to dlopen(pam_winbind.so): /lib/security/pam_winbind.so: cannot open shared object file: No such file or directory
May 5 06:32:08 zesty-test sudo: PAM adding faulty module: pam_winbind.so

Also the path is different as outlined before:
dpkg -S pam_winbind.so
libpam-winbind:amd64: /lib/x86_64-linux-gnu/security/pam_winbind.so

Confirmed at least on zesty for now, but I'm no windbind/pam expert so I struggle to see what is going on without diving much deeper - this might even be just the wrong way to set it up ... ? :-/
