Title:
  Unable to log in with AD account after update

Status in samba package in Ubuntu:
  Invalid
Status in samba source package in Trusty:
  Fix Released

Bug description:
  After performing a system update one of my users was no longer able to
  authenticate against Active Directory. This is on a Ubuntu 14.04 on
  amd64.

  The error in /var/log/auth.log was:

  Nov 24 15:08:06 haggerstone lightdm: PAM unable to
  dlopen(pam_winbind.so): /lib/security/pam_winbind.so: cannot open
  shared object file: No such file or directory

  I tried rebooting thinking something broke during the update, but I
  got the same error.

  I checked against my PC and saw that there were updates pending for
  the samba packages. I used the version numbers on my PC to perform a
  downgrade to 2:4.3.11+dfsg-0ubuntu0.14.04.1 and the problem went away.

  The affected version is 2:4.3.11+dfsg-0ubuntu0.14.04.2
