I also ran into a problem looking like this one. My smb.conf global section looks like this:
[global] netbios name = SERVER realm = EXAMPLE.COM workgroup = EXAMPLE security = ADS kerberos method = system keytab mangled names = no log level = 2 I have a feeling Kerberos authentication worked since I could log in from Windows clients in the same domain but password auth failed using smbclient and also Windows from another network which does not have access to domain controllers. These packages were upgraded automatically a while ago: - libwbclient0 2:3.6.3-2ubuntu2.17 -> libwbclient0_2%3a3.6.25-0ubuntu0.12.04.2_amd64.deb - smbclient 2:3.6.3-2ubuntu2.17 -> smbclient_2%3a3.6.25-0ubuntu0.12.04.2_amd64.deb - samba-common 2:3.6.3-2ubuntu2.17 -> samba-common_2%3a3.6.25-0ubuntu0.12.04.2_all.deb - samba-common-bin 2:3.6.3-2ubuntu2.17 -> samba-common-bin_2%3a3.6.25-0ubuntu0.12.04.2_amd64.deb I decided to downgrade to older versions. But accidentally I restored samba instead of samba-common-bin from the backup server so my downgrade command looked like this: dpkg -i \ libwbclient0_2%3a3.6.3-2ubuntu2.17_amd64.deb \ samba_2%3a3.6.3-2ubuntu2.17_amd64.deb \ samba-common_2%3a3.6.3-2ubuntu2.17_all.deb \ smbclient_2%3a3.6.3-2ubuntu2.17_amd64.deb Anyway, after I ran that, authentication worked again. My package version are now as follows: # dpkg-query -l | egrep 'samba|libwbclient|smbclient' ii libsmbclient 2:3.6.25-0ubuntu0.12.04.2 shared library for communication with SMB/CIFS servers ii libsmbclient-dev 2:3.6.25-0ubuntu0.12.04.2 development files for libsmbclient hi libwbclient0 2:3.6.3-2ubuntu2.17 Samba winbind client library ii samba 2:3.6.3-2ubuntu2.17 SMB/CIFS file, print, and login server for Unix hi samba-common 2:3.6.3-2ubuntu2.17 common files used by both the Samba server and client ii samba-common-bin 2:3.6.25-0ubuntu0.12.04.2 common files used by both the Samba server and client hi smbclient 2:3.6.3-2ubuntu2.17 command-line SMB/CIFS clients for Unix -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1572824 Title: Samba Domain Member cannot check passwords against Samba AD DC after "Badlock" update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1572824/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
