Comment 32 for bug 1677329

zesty verification

Confirming the problem with libpam-winbind:amd64 2:4.5.8+dfsg-0ubuntu0.17.04.4:

Aug 4 20:37:21 zesty-pamwinbind-1677329 sshd[4008]: PAM unable to dlopen(pam_winbind.so): /lib/security/pam_winbind.so: cannot open shared object file: No such file or directory
Aug 4 20:37:21 zesty-pamwinbind-1677329 sshd[4008]: PAM adding faulty module: pam_winbind.so

Updating to the package in proposed:
$ apt-cache policy libpam-winbind
(...)
libpam-winbind:
  Installed: 2:4.5.8+dfsg-0ubuntu0.17.04.5
  Candidate: 2:4.5.8+dfsg-0ubuntu0.17.04.5

        100 /var/lib/dpkg/status

/var/log/syslog doesn't complain about the module anymore. I added "debug" to the pam_winbind lines in /etc/pam.d/common-session and got this:
Aug 4 20:41:27 zesty-pamwinbind-1677329 sshd[6192]: Accepted publickey for ubuntu from 10.0.100.1 port 42160 ssh2: RSA SHA256:V7D2Jzg2FqANPnGlbAJWXMc/7AR0AidE7Rl86Bbqais

Aug 4 20:41:27 zesty-pamwinbind-1677329 systemd-logind[428]: New session c6 of user ubuntu.

Which confirms the pam_winbind.so module was loaded.
