As a second person has confirm that the problem also effects Windows XP
clients I have update the title of the bug. In my experience it seems to
only effect domain functions, basic SMB file sharing seems OK.
** Summary changed:
- Samba upgrade break LDAP authentification only for my w7 clients
The subject of this report is way too narrow: A system of mine was
affected, downgrade worked immediately: The system is a PDC for an NT
style domain; Samba users are system users, no LDAP; windbind not
running; Clients are XP, W7 and W10.
Samba server logged quite often:
In the meantime I downgraded. (First time in 15 years ;-)
apt-get install samba=2:3.6.3-2ubuntu2 samba-common=2:3.6.3-2ubuntu2
smbclient=2:3.6.3-2ubuntu2 samba-common-bin=2:3.6.3-2ubuntu2 samba-
doc=2:3.6.3-2ubuntu2 libwbclient0=2:3.6.3-2ubuntu2 libpam-
smbpass=2:3.6.3-2ubuntu2

Another quick and dirty solution is to:
- unplug network cable from client computer (disconnecting machine from network)
- ask user to login (if it has connected recently he/her should be
authenticated via cache on local machine)
- once logged in and on Desktop, reconnect network cable, to allow
As a quick workaround, you can downgrade samba to previous version and
restart service, that is of course not a fix but will allow end-users to
connect/authenticate again for time being. After downgrade, client
workstation may need reboot before user can connect again. If it still
does not work,
Why is nothing happening? My users can't login and are beginning to lose
faith in Linux/Ubuntu. The first one started to ask for a windows
server..

I should mention that all the servers effected where using the LDAP
backend setup via smbldap-tools. Some server were running winbind but
not all. Machines were mix of 32-bit and 64-bit installs.
Clients with login problems were both Windows 7 and XP joined to a
domain. Sometimes a user could
In response to comment #6, all the Ubuntu 12.04 machines we upgraded to
Samba version 3.6.25-0ubuntu0.12.04.2 suffered from this problem and
none of them had "allow dcerpc auth level connect = yes" in the smb.conf
file. So I think you may be looking at a different problem.

But we still have the same problem, without "allow dcerpc auth level
connect = yes" in our configuration

Finally we have the solution:
The windows machines must be up-to-date, with the samba up-to-date,
without the configuration
allow dcerpc auth level connect = yes
If the windows machine is not up-to-date, the configuration "allow
dcerpc auth level connect = yes" does not permit to connect.
If it can help, we do not have the issue with package 2:4.3.8+dfsg-
0ubuntu0.14.04.2 from Trusty.
