Comment 3 for bug 1644428

I think the error message in the log is misleading. the problem is definitely not that /lib/security/pam_winbind.so is missing, since this file did not exist in 4.3.11+dfsg-0ubuntu0.14.04.1 which worked. The module is in the same place as before: /lib/x86_64-linux-gnu/security/pam_winbind.so

But instead I think that something went wrong with the statically linking patch which was the only change introduced there:
