* SECURITY UPDATE: arbitrary file disclosure via wide links
  - debian/patches/security-CVE-2010-0926.patch: disable wide links when
    UNIX extensions are enabled in source3/include/proto.h,

* WARNING: This changes the default samba behaviour. For security
  reasons, it is no longer possible to use wide links and UNIX
  extensions at the same time. After applying this security update, wide
  links will be disabled automatically as UNIX extensions are turned on
  by default. If wide links are required, you may re-enable them by
  adding "unix extensions = no" to the [global] section of
  the /etc/samba/smb.conf configuration file.
