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

[Rowland Penny]

If it helps there is this in dmesg:

[   86.177156] samba-tool[1643]: segfault at 0 ip           (null) sp
00007fff780ce138 error 14 in python2.7[400000+2bd000]

this is after login as normal user, changing to root via 'sudo su' and
running 'samba-tool domain exportkeytab /etc/krb5.keytab'

the response on the command line is: Segmentation fault (core dumped)

You only get this response, if you run the command as root, if you run
it as a normal user, you get no response.

As I said, this was a known problem with the debian 4.1.3 package and it
went away with the debian 4.1.4 package.

Title:
  Samba dumps core if you try to export keytab in trusty

Status in “samba” package in Ubuntu:
  Confirmed

Bug description:
  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???
