Public bug reported:

I have been using Samba as a standalone server since many years and have
successfully gone through multiple Samba upgrades.

This week, I upgraded from Ubuntu 13.10 (saucy) to Ubuntu 14.04 (trusty).
This came with an upgrade from Samba 2:3.6.18-1ubuntu3.1 (saucy) to 2:4.1.3+dfsg-2ubuntu3 (trusty).
(NOTE: I did not use the samba4 package but was still sticking to Samba 3 in Ubuntu saucy)


After the update, I wasn't able to access the shares any more.

"smbclient -L localhost -U%" / "smbclient -L localhost -U user" resulted in various errors, including
* tree connect failed: NT_STATUS_ACCESS_DENIED
* (from session setup) not permitted to access this share (IPC$)
* NT_STATUS_LOGON_FAILURE
* string_to_sid: SID IPC_ is not in a valid format


I was neither able to properly browse the server/shares via smbclient nor via Windows 7 Ultimate nor Windows 8.1.

However, I was able to directly access a share from a Linux shell using
"smbclient -U user //server/share-c ls".

Not even purging samba, all related configuration, all folders,
including /etc/samba, /var/cache/samba, /var/spool/samba,
/var/lib/samba, and re-installing samba (Version  2:4.1.3+dfsg-2ubuntu3
from trusty) did the trick.


Only after installing all related packages from Debian jessie (Version 2:4.1.5+dfsg-1), everything worked out of the box again.

Thus, I think that something in the most recent Ubuntu Samba package
might be broken and kindly ask you to investigate, as there will be
several users who will upgrade and stick to this LTS release.

Thanks,
Raoul

PS. I did not try Samba 4.0 (Package samba4*) on Ubuntu saucy and
therefore cannot tell if these are working as expected.
