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

[Rowland Penny]

18th Mar 19:00
OK, just downloaded an update and I am now on 2:4.1.3+dfsg-2ubuntu4, I still cannot get a keytab, same reason. Another user has also reported the same problem on the samba mailing list. I can confirm that this problem is easily repeatable, just install a fresh version of Ubuntu 14.04, install samba and provision as a DC, then try and get a keytab, I can confirm that you will not get it!!!

The only way that I can get a samba AD server to work on Ubuntu 14.04 is
to download all the samba packages from debian jessie and install these,
then it works, so could I please plead with you to stop messing about,
drop version 4.1.3 and update to version 4.1.5 from jessie, Please, I
beg you, I am down on my bended knees ;-)

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

Status in “samba” package in Ubuntu:
  New

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???
