[Bug 1644428] Re: Unable to log in with AD account after update

[Launchpad Bug Tracker]

This bug was fixed in the package samba - 2:4.5.8+dfsg-2ubuntu2

---------------
samba (2:4.5.8+dfsg-2ubuntu2) artful; urgency=medium

  * Add extra DEP8 tests to samba (LP: #1696823):
    - d/t/control: enable the new DEP8 tests
    - d/t/smbclient-anonymous-share-list: list available shares anonymously
    - d/t/smbclient-authenticated-share-list: list available shares using
      an authenticated connection
    - d/t/smbclient-share-access: create a share and download a file from it
    - d/t/cifs-share-access: access a file in a share using cifs
  * Ask the user if we can run testparm against the config file. If yes,
    include its stderr and exit status in the bug report. Otherwise, only
    include the exit status. (LP: #1694334)
  * If systemctl is available, use it to query the status of the smbd
    service before trying to reload it. Otherwise, keep the same check
    as before and reload the service based on the existence of the
    initscript. (LP: #1579597)
  * Remove d/p/fix-1584485.patch as it builds a broken pam_winbind
    module. There is a fixed version of that patch attached to
    #1677329 but it has not been vetted yet, so for now it's best
    to revert (again) so that pam_winbind can be used.
    (LP: #1677329, LP: #1644428)

Title:
  Unable to log in with AD account after update

Status in samba package in Ubuntu:
  Fix Released
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
