[Pkg-samba-maint] Bug#783658: All authentication fails with NT_STATUS_NO_SUCH_USER if server's NetBIOS name is >15 chars

[Christopher David Howie]

Package: samba
Version: 2:4.1.17+dfsg-2
Tags: upstream, fixed-upstream

Samba 4.1.17 appears to have a bug causing all authentication attempts
to fail (internal error NT_STATUS_NO_SUCH_USER) if the NetBIOS name of
the server is over 15 characters long.  This includes the inferred name
if "netbios name" is not set in the config file and the machine's
hostname is over 15 characters long -- therefore the config may not even
be "incorrect" but authentication still break.

This was reported upstream previously
<https://bugzilla.samba.org/show_bug.cgi?id=11008> and is fixed in a
newer Samba.  The fix may need to be backported.

A workaround is to set "netbios name" explicitly in smb.conf to a string
of 15 or fewer characters.  After restarting Samba, authentication
should work as before.
