Security update for Samba (important)

This update of Samba fixes one security issue and several
bugs.

The security fix is:

• Ensure that users cannot hand out their own
  privileges to everyone, only administrators are allowed to
  do that. (CVE-2012-2111

  > )

The non-security bug fixes merged from upstream Samba are:

• Fix default name resolve order. (docs-xml, bso#7564).
• Fix a segfault in vfs_aio_fork. (s3-aio-fork,
  bso#8836).
• Remove whitespace in example samba.ldif. (docs,
  bso#8789)
• Move print_backend_init() behind init_system_info().
  (s3-smbd, bso#8845)
• Prepend ‘/’ to filename argument. (s3-docs, bso#8826)
