[Bug 1289318] [NEW] Samba dumps core if you try to export keytab in trusty

[Rowland Penny]

Public bug reported:

If you set samba up as an AD controller in trust and then run this
command:

sudo samba-tool domain exportkeytab /etc/krb5.keytab -U Administrator

Nothing seems to happen and the keytab is not exported.

Run 'sudo su' and then run the command again, you get:

Illegal instruction (core dumped)

Unlike most of your bug reports, I actually know the cure, firstly the
cause, On debian it was found that parts of samba were being built
against the wrong libs, this was discovered in version 4.1.3, a patch
was developed.

How to cure the problem, very easy, move to debian version 4.1.4 or
4.1.5

I know that you may say that it is a bit late now to upgrade a package,
but think about it, do you really want to ship an LTS version with a
badly broken major package, if it is a very easy fix???
